A "defective corollary discharge mechanism"...
Hi, I have just read Current Research Investigations of Corollary Discharge by Michelle Coleman ( http://serendip.brynmawr.edu/bb/neuro/neuro03/web2/mcoleman.html ) and would like to share some of my own ideas...
Is one of the most influential cognitive models of auditory verbal hallucinations correct in its claim that “a failure to adequately monitor the production of one’s own inner speech leads to verbal thought being misidentified as an alien voice”?
A self-monitoring mechanism (or “corollary discharge” mechanism) is needed to generate an act of will and what "should correspond to nothing less than the experience of will or intention" can be assumed to attenuate and "tag" a self produced experience by accurately predicting the sensory consequence you are about to produce.
Quote: “...Before someone talks, a neural signal travels from speech production areas to auditory cortex. It carries a prediction of the speech sounds based on a copy of the motor command and triggers a “corollary discharge.” If the corollary discharge matches what the speaker hears, as it should when the sound is self-produced, the sensory experience is reduced. The sensory experience thus carries a tag declaring it “self-produced,”... ” Source: Schizophreniaforum.org
http://www.schizophreniaforum.org/new/detail.asp?id=1343
Irwin Feinberg was the first scientist to propose that these discharges "are themselves conscious" and "correspond to nothing less than the experience of will or intention"!
Quote: "...motor commands are monitored and evaluated as they occur, before the effector have been actuated... ...Whereas internal feedback associated with simpler motor act is below the level of consciousness, one might postulate that the corollary discharges accompanying conscious thought are themselves conscious. If so, the subjective experience of these discharges should correspond to nothing less than the experience of will or intention..." Source: Schizophrenia bulletin (VOL. 4, NO. 4, 1978) Efference copy and corollary discharge: implications for thinking and its disorders, Irwin Feinberg
http://schizophreniabulletin.oxfordjournals.org/cgi/reprint/4/4/636.pdf
For whatever it's worth, my own attempt to understand: To consciously control covert speech with regards to a certain goal by adequately monitor the production of one’s own inner speech may in competition for limited attentional resources attenuate all features matching the sensory consequence you are about to produce. ("...motor commands are monitored and evaluated as they occur, before the effector have been actuated...") The effect when you are forced to divide your attention between two similar tasks can, sustained for a short period of time, be assumed to attenuate the sensory consequence you produce while an act of will tags a self produced experience with the help of a corresponding prediction! (All features matching the sensory consequence you are about to produce (exafference) and the sensory consequence you produce (reafference) are attenuated!) Incentive motivational signals ("a type of motivationally-biased attention") can be assumed to shift the allocation of processing resources from what generates the ability to consciously control covert speech to what you are able to select with a corresponding top-down sensory expectation...

OCD
Hi Serendip, and Thank you so much for the great job that you are doing here,
actually, I do have OCD, with compuslions and unwanted thoughts etc,
but what you said at the end of your paper seemed to make so much sense, about the amygdala playing the part
actually mine started after a period of an inward and very intense fear and anxiety about something that I really loved to do but thought was wrong, I remember being very stressed and very emotionally entangled then, the symptoms started from then, and only, only times when I try to be in peace, and be my former self again, and try to think that none of my thoughts are normal or true, for those moments my compulsions completely, COMPLETELY disperse, I really think it should be the amygdala, it's all a saved emotive reaction of my brain and no thoughts interfering in it anymore...
I still believe in and pray for peace, for me and for all the others like me out there....

Epilepsy, your report
Hello; Your report on Epilepsy coment on how modern we are, then the odd injuries to the tongue and mouth are backwards. These injuries are caused by ones, as fools, sticking spoons in the mouth and injuring then! Sometimes even ripping the tongue out. They still think one will swallow their tongue and then not be able to breath. They, normal people, are too dump to realise 1. We have noses! 2. The throat can Not be blocked! If they pushed they own tongues back and even stuffed their fingers in, the throat area can Not be blocked!
Wow! This website is AMAZING!
I'm a grade 8 student and I have recently just started a science fair study on whether the cat or the mouse is more intelligent. I tried searching up my research questions on other websites and they were just to complicated for me to understand. Until I found your website I didn't even understand the parts of the brain!! I just want to thank you for making this amazing website and making the information accurate and readable! This website saved my science fair project and I will definitely be using it for future reference:) I only have one complaint and that is that I sort of got lost on certain page because I couldn't go back to the page I wanted. Other than that I can't say enough about how awesome this website is!

For a few years ago I had a vision, like a flash on the
Retina. I saw a very detailed image of jesus with a crown
Of thorns. It happened during a prayer and up to
That day it was the only vision I can remember ever
Having. Last week I was scared and prayed for
Protection. Only a few seconds later I saw a vision
Of an angel with wings, cross and a bow. Apart from
These two events I have never had any visions.
I have never seen another face, image, food, sky, tree or
Anything on my retina or I am awame.
Can my brain make up these images and why have I
Not seen other things?

Huntington's Info
Hello, my name is Luke Saldana and my family has HD. I'm the oldest of five children. All from different mothers. My three youngest siblings are sick or have already passed away from the disorder. My youngest half- brother died at age 14. He showed symptoms at age 7. The next in line was my half-sister, who is 23 and is confined to a bed due to the disease and my other kid half-brother, who is 27 was diagnosed last year and is showing signs of chorea. I have another half-sister, that is older than 27, but younger than me. I don’t know where she is or if she is sick. I am 40 years old and am a material engineering student who is writing a bio paper for class.
I want to know about his DNA having long CAG repeats as he gets older and spreading it to his offspring as he aged. Can you share with me any links that might help in my search, or do you have any nuggets of info for me.
Thanks you for your time. Luke Saldana

lead in water
There is another culprit in the story of lead in our water: the lead industry. For decades after the lead companies knew that lead pipes could cause lead poisoning they continued to sell and promote lead pipes. (see The Lead Industry and Lead Water Pipes: "A Modest Campaign"; Am J Public Health. 2008;98:1584–1592)
Forced Bias
In your Free Will behavior experiment there are several problems with anyone who might 'try' to see left pointing arrows at first glance. First, since the right-pointing arrows are green and darker than the yellow left-pointing arrows your eyes are attracted to those arrows first. Also, because the yellow left-pointing arrows are the same color as the background/border, your brain ignores the background and focus on the green arrows because they stand out from the background (which includes the left pointing arrows). In order to avoid a forced bias, the background should be a white or a black and both directions of arrows should be neutral, non-competing colors. Lastly, there are almost twice as many right-pointing arrows, and therefore twice as many chances for your eyes to see a right-pointing arrow. Just something to think about when considering the brain's real free will in the situation.
Hi,My name is Kathryn and
Hi,
My name is Kathryn and I'm the author of a new book called Crochet Saved My Life. The book is about the mental and physical health benefits of crochet (and some other crafts). It includes my personal story of crocheting to cope with depression as well as the stories of many other women who healed from a diverse range of ailments thanks to crafting.
I just wanted to let you know that your site was mentioned in passing (with proper reference of course) in this book. I referred to some of the information that was shared in the article on your site titled "An Incomplete List of Cognitive Skills".
Have a great day,

Dopamine and Addiction by Imran Siddiqui
Please forward this comment to Imran Siddiqui. My father was a gambler his entire life. In January of this year, he informed me that he was depressed because he had very little money left. He was beating himself up and calling himself a loser as he has done several times in the past. He called me his "little psychiatrist" because I always listened and tried to get him to focus on all of the positive things in his life. His wife was also a gambler. It is the following powerful statement he made to me in January that haunts me. He said, "If I can't gamble, then I might as well die!" He went into a depression, ate very little, and a rapid decline in his health became evident including a diagnosis of Parkinson's disease. He died last Sunday, August 5, a few days after reaching his 75th birthday. Please contact me if you want to do any more research in this arena. Thank you.
Vegan Diet
I just read your article on veganism. I am a vegan, and I would have concluded from your article that it is a healthy way to live, so I was surprised by your conclusion that it is not. The reason you gave was that it takes careful planning to be successful. I would offer that it should take careful planning to be successful on any diet. Most of our diseases come from the way we eat. American diets are notoriously bad and there is rampant obesity in our society. I take a daily regimen of probiotics to keep up my immunity and one of the benefits of that is a healthy vitamin B12 level that my body provides me. I don't do fads like all fruit or all anything. I eat mostly green and colorful vegetables, some fruit, beans, nuts, and seeds. I supplement my diet with plant based protein powders, vitamins, and minerals and antioxidants to stay young. I am 69 years old and feel better than I ever have in my life. I am sensitive to a lot of foods so have to be careful about what I eat as well. I stay away from processed foods as much as possible and eat as close to nature as possible with the exception of the protein powder. Most of my food is organic as well. I never get sick anymore either. Finally, my weight is what it was in my 20s, another benefit.
i did not sleep for one month n hardly ate a thing
please help i did not sleep for one month. and it was not due to drugs my brain just exploded from too much stress and an over active thyroid that i did not know i had levels being double what should be. Now I cant manage my day to day life cant do a thing but sit online looking for some miracle cure that is just not out there. THis is hell. Nothing on the net is offering hope for a cure! PLEASE helpme
Alice in Wonderland Syndrome
Hi. This is for anybody on Serendip, but specifically to Caroline Feldman. This is a video mini-documentary I made about my possible experiences of Alice in Wonderland Syndrome. I was motivated to make it because my recent experience did not meet really any of those listed by AiWS's Wikipedia article, so it's puzzling. I just wish for scientists who are knowledgeable about the condition to see this nine minute video and share their opinions. (and subscribe to my channel, if you care to.)

Lead Poisoning
Hello,
I read your article on Lead Poisoning: http://serendip.brynmawr.edu/bb/neuro/neuro00/web2/Patel.html
I am wondering if I can speak to the writer of that article: Anjali Patel.
My question is: After lead and mercury has been removed from a person's system, can myelin be regenerated when scars already exist from lead poisoned (during childhood) and mercury poisoned (during adulthood)?? or is that a permanent damage?
Thanks!

Need Help
I am a research scholar from India.I went through the resources available on interactive chemistry. I really find them quite useful. The great thing about them is that they are free. Actually, i would like to use some of these resources particularly tutorials and quizzes for teaching secondary school students. But unfortunately the schools here don't have internet connection. Are these resources freely downloadable? Can you people please help me out?

High BDNF Production In Children Due to Physical Labour
If what you pose in your article is true:
High BDNF production would occur for children under the age of 10 if subjected to physical labor.
E.g. Working on a farm, Logging, weight-training.
Does this increase in neurogenesis represent a higher neurological function, but limit an ability to focus, retain social memory, and derive pleasure from any activity other than physical stimulus?
Would it be possible to alter the occurring performance with drugs developed to focus the hippocampus?
drug babies syndrome
MY name is Allie and I have many problems due to the drugs that my parents took while she was pregnant with me in her tummy my teeth did not grow properly my cells in my brain did not form properly my mom smoked weed and did drink and more other drugs doctors did not know the real cause of which drug did what damage to me. I am now 38 my knees are that of a 90 year old because i have been diagnosed with tmj in my joints not just in my jaws i have joint, ligaments and tendons that are slowly not working properly you say weed is good or it don't harm any one but it does if you take while your having a baby sure the baby looks normal but when they grow up its harder for them to learn to keep information in apply their there smarts they are different in the way they think to them its rational to those around them they are considered weird and different. its hard to make friends when my teeth did not grow right they said i needed braces but come to find out i have teeth in my nose cavity and still have baby teeth because the adult teeth behind them are laying side ways in my facial structure you would not know this if you looked at me you would just see me smile and wonder why my teeth are broken and bucked but exrays wow even i was surprised I have no idea what it would take for me to just have a pretty smile to much money that i don't have i did get a quote one time to have them pull my teeth and replace them but my smile would still not be straight teeth and no thank you they cant just pull the baby ones because the adult teeth are laying side ways on top of the babies its really hard to explain but here is the deal all drugs are bad especially if you think you may be come a parent it is the child that suffers and is the child that is going to have an abnormal life and looked at stupid because she or he thinks different looks normal for the most part but suffers from many complicated ailments like depression anxiety A D D Adhd all together and when they take pictures of your brain it never grew normal Now i don't want sympathy from any one it is no ones fault but my parents thc levels in the sperm and thc levels in my moms blood all played a role in how i developed and my brain is still not right I am a mother of 2 kids both girls I did not drink nor smoke nor do drugs and to this day I do not do any of those things because i live the consequences of someones choices on a daily basis. what you do with your life is your choice but when you are having to be part of someone else your life no longer belongs to you it belongs to the one inside that you are responsible for. I have been trying for many years to find out what drugs and what kinds of drinking did this to me but I am not a statistic I have not had a family but the one i created my mom let me be raised by the state because she was to busy being selfish and not caring towards me but I have one question that no one can answer why would you risk your life and the quality of the life one has inside what does one gain by making these choices its not fun any more its more of a chore then any thing my whole life i have ended up being friends with drug users trying to make them change their mind on getting high drunks trying to get them to a point in their life where being sober is more productive but I have yet to suceseed in this problem. for all the ones that drink and smoke weed and do hard drugs no one in your life benifets from your choices it hurts the ones that care for you the most and eventually you will have nothing to show for the life you lived for in the end you will own nothing have nothing because for what you thought was a good time turned into a really bad habbit that has consumed your life and the life of those around you. and in the end no one wins kids loose parents that they really need in their young life and parents loose kids due to the abuse and lies and demons that they have chased and found and now they belong to them not you any longer when in reality as parents we do our best to love them guide them show them but when in due time it becomes their choice of what they are going to do and were all accountable for our own actions its just sad when it s the kids in the middle that suffer the most because we did not ask to be born in to it
alisson and the lithium article
I have to say that lithium has given my 10year old back his life. He is happy for first time in 5 years. He has very little hand tremor and is back to being a typical kid.

Women in Walled Communities
Very interesting idea - Women in Walled Communities, 360 course cluster: But imagine my surprise when I discovered that colleges and prisons are the communities in question! Notably missing are women's monasteries, many of which are indeed homes of silence, voice, and vision, certainly as much as and maybe more than the above. They also are in a deep sense “penitential” communities, not in the sense of punishment but in the sense of perfecting the heart/mind. Although religious traditions (Quaker, Mennonite, Buddhist) are mentioned, walled contemplative communities are not. Study of these communities would I think offer very interesting and useful insight.
Tacit Knowledge
I was browsing on internet for tacit knowledge and stumbled at your article ! Its really great read .I still wonder how can one make use of the tacit knowledge they have for their own development? If one do not know, what they know, is there a way school can help one to make the maximum use of the tacit knowledge they posses to make an individual dream/ imagine and grow ? Is there a way where school's / companies can contribute to help and individual grow ? I understand that every individual born has the tacit knowledge within him/her and we make use of it unknowingly under different circumstances. Is there any way we can capture how we think of under certain circumstances? Is there any more research done on this subject ? I am really interested to know more on if a school can help an individual make use of the tacit knowledge he/she posses. Any feedback from you will be greatly appreciated.
RE: Some thoughts on science education, education, Ameri
I realized this is an old post (1991), but I just stumbled upon it..and I must say I loved it and related to every bit of it! It was thought provoking and articulated nicely. I find it relevant and to the point, maybe even more so today than in 1991. In the same way "telling the truth is a revolutionary act!", thinking is vigilantly discouraged. In my experience, many people--sometimes your own family, really get "put off" when you bring up things that make them think. I admire and respect you PAUL GROBSTEIN [ DEPARTMENT OF BIOLOGY BRYN MAWR COLLEGE ], for your honesty, integrity, and perseverance in the face of adversity; as well as your insight and wisdom. Thanks for pointing out the 'elephant in the room'...and thanks for "thinking so much" and writing this great article. It is now on StumbleUpon. :) love and blessings! ~ Linda

Jesus.....back
and to prove I'm the real deal I explain (in all languages as promised) how I performed 2 miracles feeding the 5000 and the miraculous catch in my key video "the announcement". More will be revealed in due course over the next few months as the world wakes up slowly to the reality I am back. Of course some will say I am an imposter but the reality is no one will wonder how the miracles were performed anymore as my truth will be embedded in the minds of man and everyone will know it's the truth even if they deny me intheir hearts. Spread the video (facebook-Jayzus Christo, twitter-@themessiahme, email etc) if you want to speed up the coming of a world free of oppression, violence, paedophilia etc it's going to happen but you can help speed it up. to doubt is normal but condemn me at your peril your name shall be noted. Those who muster faith and pass on the video shall be rewarded (perhaps despised by many but cherished by me).
Love Jesus

A Failure of Will—A new way of thinking about Depression Eliza
My husband just sent me the article : A Failure of Will—A new way of thinking about Depression, by Elizabeth Diamond
My husband is the only person I have ever met that doesn't just "snap out" of his depression. Its debilitating and often causes me to
become depressed as it is his only mood for long periods. This article clearly articulated the way he feels and encouraged him
in his depression. He has been on anti-depressants which seems to inevitably invite guilt, as if taking them is admitting that there
is in fact something wrong 'with me'. But reading this has helped us both to see that there is more at play than just my husbands
failure to be productive and the ability to will himself to happiness. We recently moved and he ran out of anti-depressants before we could get
him more. Its a terrible reminder of how well the anti-depressants stabalize his moods, although they do not fully cure him. After
reading this my husband seems open to not just the medication but support from a counselor. The article has helped me to see
what he is "feeling" and how/why he can't simply "snap out" of his depression. Thank you for this well written and researched paper.

Free will experiment
I would like to make a comment about the free will experiment. Let me begin by talking about flipping a coin - something that seems "random", but in truth is entirely predictable. The coin is subject to the laws of physics, and will follow them - the result of the toss is directly a byproduct of the particular way it was flipped.
In much the same way, your brain is in a particular state, a very complicated one that is a result of your biology and your history, combined into a vortex of neuronal connections. The state it's in is predetermined to see the arrows pointing one way or the other - perhaps a result from being left or right handed, being color blind, growing up in a particular way, or any other factors, etc. Either way, the moment before you loaded the web page you were going to see the arrows pointing either left or right at first. Your brain has learned to parse through visual data coming from the eyes, and it will do as it has always done upon first glancing the arrow image. There was no free will, there was a brain that had learned to make sense of incoming data, and had learned to do it in a particular way. Back to the coin - it is a fallacy to assume that a complex manifestation of seeing an image is beyond the laws that made it happen.
And then you read the statement about whether they are pointing left or right, and you again look at this image, this time more closely. You notice the arrows pointing to the other direction from which you first noticed. Now we are beyond whether the arrows point left or right, and onto the second part. Do you choose the direction you originally saw the arrows pointing, or do you choose the new direction?
I still believe this is not free will. You have a particular history of being tricked on the internet, and probably didn't care too much about what you chose, as you just wanted to see the results of the experiment. However complex your thoughts, they too were a result of your raising and your particular state of mind at the moment before you loaded the page.
If you didn't feel like reading all of that, here's my two cents: you could go back in time, load the web page again, and you would choose the same things again. You have raised your brain a certain way, and it behaves as it does. To believe in a conscious choice that is "above" the physical domain is silly - the coin toss was not random.
This isn't to say your choice was predictable - quantum mechanics indicates that there ARE truly random occurrences, and so perhaps a theoretical perfectly reconstructed model of your brain would not make the same decision as you. But to mistake quantum randomness for free will is a bit of stretch, and certainly a fallacy of the human perspective
Split- Brain Behavior by Maria Vasiliadis
First of all let me start of by telling you a little story. I sustained bruising to the right side of my brain from getting hit by a car, and as a result, grew up with the effercts of slight clumsiness on the left side of my body. I am 34 years of age now (will be 35 years of age in the month of June, 2012) and have grown up with various difficulties with balance and coordination; one of my difficulties is with developing a good touch typing speed, although I do my best. The question that I would now like to ask regarding split brain behaviour is; if I had been given the split brain procedure when I was young or even if I was given this procedure now, would it give my right brain a chance to heal better and/or faster, when not beeing connected to my left brain? I am just curious as to whether the split brain procedure could have ever been used for someone like me.
Thankyou, and I look forward to your response....

ECT and Memory Loss
You fail to expound on the memory loss after bilateral ECT. I had 27 ECT treatments between April and August 2011 and about half were bilateral. I have had a lifetime of depressive episodes. I have had extensive memory loss which hasn't yet resolved. It follows what I am just now finding out is the typical pattern, spotty and mostly for the past. I have lost the whole last year, but is OK since it has been pretty bad, but what distubs me is that I have lost most of my professional knowledge. This is glossed over in most current articles. Even now while I am trying to regain my knowledge and reread my old textbooks, the information is very hard to digest and remember. I am a Masters level counselor and RN and I am very motivated to return my career, and my depression was addressed so it isn't that I am malingering or that there are are other problems. I must say though that I am becomming discouraged that my problems are being discounted and glossed over. I can find documentation of these difficulties in the older research, but the newer stuff is so enthusiastic about ECT that it stops cold when it comes to problems and just says there aren't any. Well you guyes are in denial. There are problems. The studies I have found are small and narrow. There is a real bias. My depression is coming back and I am scared to tell my doctor for fear he will insist on more ECT. There will be no more ECT. I am finding other ways to deal with it. It did help me, but these other ways were there then and I wish he had helped me with them then, but he didn't want to take the time. I think doctors like ECT now because it is quick and easy for them. Doesn't take the personal time with the patient that life stlye important change take. We should be looking at those and return to humanity instead of a lifetime of ECT treatments that remove the patient from our care even further. Where is our humanity going?

Comment for "Chocolate on the Brain"
To Kristen Coveleskie:
I read your paper "Chocolate on the Brain" http://serendip.brynmawr.edu/bb/neuro/neuro04/web1/kcoveleskie.html and wanted to let you know that your research is dead on. My massage therapist kept telling me over and over how I ate too much chocolate and that I needed to stop because of the sugar content. So I spent last spring semester tapering off "the chocolate" and quite all together this past summer. Want to know what happened? Over the summer I became lethargic, gained 15 pounds, became stressed out, and had problems with migraines.
I have four diagnosed disorders -- essential tremors (symptoms like parkinsons but without brain degeneration), anxiety, hypothyroidism (causes fatigue, mood imbalance, etc), migraines (which cause pain, seeing "auras", mood imbalance, etc). All of my symptoms for these disorders were exacerbated.
So around August I went back on chocolate... I figured if I was gaining weight anyway I might as well be eating chocolate. Since then my moods have evened out, my energy has increased and I've lost 10 pounds. It has also helped during the beginning stages of a migraine.
My body is extremely sensitive to "mood altering" substances which is why my doctors cannot give me medication for my disorders (they are all too strong and make me really sick/out of it), I can't drink alcohol or do drugs. Turns out that there is just enough of the chemicals I need in chocolate to have the same effects my doctors would like to see with traditional medication. Missing my daily "dose" of chocolate has the same effect on my body as missing a daily dose of physician prescribed medication. So, for some of us chocolate isn't just a comfort food ... it is a cure.

Ataxia
The Ataxia article from this site is one of the most accurate and heart-felt sources of information that I've read. My ataxia was diagnosed only 4 years ago, but I have a hunch it has been around far longer. Kudos to the authors and developers involved in creation of this piece. I think it deserves required reading status for all providers of health care.
"Free Will"
I think it is important to clarify that this "free will" is not the same as the free will that is used in the context of determinism and indeterminism. Whether or not we can make a decision to see an arrow one way or another does not prove that we actually made that decision for ourselves, as the term free will implies.
Art Sight
I am a practicing artist of six years now in traditional realism. When I draw/paint I look at something and time seems to stop and I rely on an 'instinct' to tell me if my drawing/painting is accurate or not. I paint for hours and it feels like a very short period. In fact my feet often fall asleep from not moving. I am imagining this to be similar to blindsight. I experience a timelessness and I experience a discomfort when my image is incorrect spatially or in value. But color doesn't register and it must be consciously considered before hand. There is speculation that art is a right brain activity but I'm not sure I agree because I use both eyes to paint/draw. I feel certain there is an subconscious element to what I do. And perhaps the subconsciousness is unaware of time. I'm convinced the images I create have a subconscious origin and that much information in the image is 'unseen' but there all the same.

Wowed by your Website
I came upon your site today as I questioned Google, "What part of the brain processes visual stimuli?" Google took me to a typically wishy-washy "answer" Website, but happily one of the writers referenced a page on Serendip.
AHHH, it felt so good to encounter such well-written, witty and ACCURATE info! This Website does its job better than anything comparable, and I do a lot of health writing, so appreciate it all the more. Write on!
The Abstract Concept: "I Think, Therefore I Am"
Fellow Toastmasters & Guests, the words of René Descartes have remained to haunt thinking men and women like you and me for three and a half centuries. I say “haunt,” because many of us are still trying to come to terms with the meaning of this lofty, elusive expression. I must confess that it is intrigue that I feel – a compelling, fascinating curiosity to resolve abstract thought into tangible meaning. My purpose is to convince you that I think; therefore, I am...capable of cracking this one!
If I were to offer you a basic explanation of Descartes, it would probably go like this: “I am able to think, therefore I exist.” But there’s an instant shortcoming to this interpretation, because there are many entities in existence that do not enjoy the faculty of thought; there are even human beings who do not actually think (I pray that all toastmasters do!). Do they exist? If you insist that any claim to existence is dependent on the capacity to think, then I beg your pardon, but you must be sitting squarely on your heads right now, because those chairs do not exist – they are incapable of thought!
What is your opinion; do you exist because you think? Or do you think, because you exist? I daresay, there are those who do neither, and so they neither exist, nor do they think. If you do not have a life of your own, you just as well do not exist, because you serve yourself no purpose. And if you do not have thoughts or opinions of your own, you certainly are short of a mental plane on which to perpetuate an existence. I put it to you that I think because I exist. In other words, “I exist, therefore I think.” Now that’s a complete reversal of “Descartesian” philosophy. It means that mind follows body, fattened by the assumption that wherever there is a body there should be a mind.
Let’s get personal: I look at this toastmaster’s audience, and I see you – or so I think; but what I really see are your shapes and forms (your bodies). It is mere assumption that, because your bodies are sitting in this room - on chairs that may not even exist, since they do not think - then your minds are also here. But it is not even a safe assumption; for some of you, while sitting here well-dressed in body, are mentally elsewhere planning tomorrow’s meal menu or wondering how to get the rest of your day’s work done after this meeting.
If we were to reverse the principle to its original state – “I think, therefore I am” – Descartes would be pleased, because, to him, the body was less real than the mind. According to his reasoning, "the mind and body were two separate and distinct entities, but even the body was not so certain a thing as the mind, because, like everything else in the world, the body could only be sensed because there was a mind to sense it." Shall we then reason that body follows mind, so that wherever there are robust minds there must be wonderful bodies?
I-don’t-think-so! Doesn’t Descartes himself insist that “the mind by which I am what I am, is wholly distinct from the body, and is even more easily known than the latter …”? It is neither ideologically logical nor conscientiously consistent to make truth of the notion that mind and body must always swoon in matrimonial bliss. After all, the body may very well be on the decline whenever the mind is on the uprising, because bodily emancipation must be the antithesis of mental liberation.
That’s brain and brawn fighting for supremacy. Descartes could scare find his own body, because the mind by which "he was what he was" had attained such sophistication and elegance that any other form of existence was, for him, immaterial. To be complete in mind was to have no need or care for a body: “I think, therefore I am.” It is enough to know that I think, because that makes me real. And as long as I can think, I can also conclude that this mortal shell, which I can sense by seeing light, hearing sound, feeling heat, smelling the roses, and tasting Jamaican jerk, is my body.
By extension, give me a mind, and I can “think” myself a body; but give me a body, and I may not necessarily be able to grow myself a mind. The body cannot do what the mind can accomplish. Descartes contends that the body could only be sensed because there was a mind to sense it. My contention is whether the one can exist without the other. Would you be happy with a mind that found no refuge in its own material tenement? Or would you find contentment in a physical frame that had no capacity to fathom whether it was a zombie or a corpse?
Where there are no bodies, I do not look for minds, for I perceive that the one must coexist with the other. According to Asian philosophy, Yin-Yang is the balance that coincides and coexists in all things to make life complete – dark and light, female and male, low and high, cold and hot, and, by the same token, body and mind. In truth and in fact, Descartes’ “I am” cannot be limited to mind only, but must embrace both mind and body, because we all exist on a physical as well as a mental/spiritual plane. For you and for me, it is a tripartite equation that may resolve this issue: body (b) + mind (m) ≡ behaviour (bh) or bh≡b+m. Body is the tangible, earthly, physical representation of my “I am”; mind is my perception of sensations that impact my body – the think symbol of my “I am”; and behaviour is change in me resulting from what I perceive as sensations impacting my body as well as my thoughts.
Let’s apply this formula to Descartes’ theory: I think (behaviour), therefore I am (body + mind, i.e., human). It then becomes an exclusive claim that only human beings can make. Body without mind makes me corpse or vegetable, and mind without body makes me spirit; but body with mind makes me human. “I think; therefore, I am [HUMAN].

NB The above is the text of my Toastmasters Speech Project, "The Abstract Concept," from the "Speaking To Inform" Manual.

Contacting Sarah Ledoux
To Whom it may concern,
I am a playwright from Perth Western Australia, currently writing a play exploring post natal depression and sleep deprivation. I would like to get in contact with Sarah Ledoux about the possibility of transcribing a section of her paper, and quoting it in the play. If someone could let me know how to get in contact with her, or what the right channels would be to explore this idea that would be fantastic.

Someone may have mentioned
Someone may have mentioned this, but after looking at your arrows experiment it reminded me of some of my earliest thoughts on the subject of free will. I would like to point out that you are born with the ability to see the arrows either way, so that is not free will. Also, while you do choose which way, you do not choose what you choose. Meaning that you do not choose what your natural inclination will be, and while you can choose to go with the opposite of your natural inclination (I did, I went left), then you did not choose to have the idea to go with the opposite of your natural inclination. You can talk yourself down that loop all day, but eventually it will come to something you were either born or raised with.

Holding off Improbability by Zack Gunau
My mother passed away on Saturday evening June 4 2011. I wanted my family (sisters and brother) to consider AGR (Anatomical Gifts Registry)specifically because our funds were low and it means our mother contributes to another life. My sisters were appalled and wouldn't hear of it. My 17 year old son knew his aunts wanted to do a viewing of his grandmas body. So he looked up embalming proceedures...specifically this artical. He's a sort of environmental advocate, specifically when it comes to death. He said, "Ma you need to read this article on embalming. See if your sisters...my aunts would consider freezing the body for viewing... We're looking into it to see if it's possible.
Gunau's story is a great article and incredibly informative (http://serendip.brynmawr.edu/biology/b103/f05/web2/zgrunau.html). I don't know if my sisters would have been ready to read this. I wish we had seen this article before my mom died. They're caught up in the emotion of loss...having a hard time being rational. In my mind it doesn't make sense to go in a hole for funeral expenses. I am the oldest in our family and also trying to let go of my need to make them do what I say. She was their mother too. However, I'm having a hard time with polluting the earth with my mother's body just because I need to see her in her pre-death state. It all seems to by into an illusion that she will always look this way. In anycase, good article. I hope my sisters will consider the freezing process or a direct cremation.

Blood Acohol Level of 300.0
First I would like to say thank you for giving me the ability to ask this question and receive an answer! I am very worried about my husband. He is a 52 year old African American, approximately 155 pounds and was taken by ambulance to the hospital tonight for blacking out after drinking with his "friends". The doctor found his blood alcohol level to be 300.0. My question is how much alcohol did he have to drink for his level to be so high? I am in need of this information due to the fact that he is borderline "wet brain" and sclerosis of the liver. As you can see, I am in dyer need of your assistance at this time.
Thank you in advance

Schizophrenia article
I did not like how the author of the schizophrenia article said that this is the "only world that exists." That is precisely what's wrong with most people's interpretation of schizophrenia. Look up The Many Worlds Theory of quantum physics. It explains almost everything that schizos go through and it explains how free will exists and how the mind is capable of anything.

cephalization, and intelligence.
In a blog I recently wrote, analyzing the meow of a cat, I noticed that there was a chance for me to prove my theories that Dogs, are in fact superior to cats, and that there might be non subjective data to prove such a theory. I do not believe it is up for interpretation. I believe dogs DO in fact have superior nervous systems to cats. They are a more evolved animal. They are social animals, which means they have need, and are capable of more intricate ways of expression, which they would need in a pack. Whether it be a dog/human pack, or the traditional dog pack. Cats are singular predatory animals that while being super efficient hunters, have much fewer social skills, and are much less capable of expression. I set out to find data to prove this. I first looked for size ratios of brain to body size, but as your data suggests, that proves nothing. so then I thought about the intricacy of the physical brain. Is is smooth, or does it look like a maze. I believe your cephalization, may be indirectly related to how intricate the surface and depth of the brain may be. I believe a more intricate brain, with more "channels" for lack of a better word, would be more dense, thus more cephalized.
I would like to get your thoughts on this for one, and two, I would like to ask permission to re-post your findings on cephalization along with some of my theories, and whatever data I can find, as I would like to set out to informally prove that dogs are in fact Superior to cats, using empirical data.
The original blog post that spawned the idea is below.
thank you!

married to spouse with panic disorder
I've been reading much on your website on the brain and trying to figure things out. My husband suffers horribly from panic disorder, which as you've aptly stated before, can cause a recreation of reality. When he suffers from a panic situation, it immediately goes to rage and screaming for what I've done (or my 5 year old) to cause it. We're not perfect, but the majority of the time, we weren't even involved with what may have occurred, so within seconds, he realizes what he's done and then re-creates the reality of what happened. He changes the situation and words that were said, to being entirely not what occurred.....but to his favor so it appears that he was calm and loving when asking us something.
I'm not a bitter wife pointing fingers, but one who is desperate for help on where to go. He's been on meds that were listed in previous postings, has done hypno-therapy, cognitive therapy and marriage counseling. My daughter and I live in fear daily from his rage and are worn down by his need for continual reassurance that he's accepted and not rejected.
I'm lost and am unsure of what to do. If anyone out there has a suggestion, I will try anything to have a kind, loving husband/father for my daughter and I to come home to, and for him to have confidence in himself and not re-create his reality because of his fears. Thank you for anyone who can help!
Sleep paralysis
Good day,
My name is Danielle and for years I suffered nightly with sleep paralysis, only at the time I had no name for it and even consulted a neurologist about my condition. My friends and family, while sympathetic, could not understand what I was talking about at all. I had all of the classic symptoms, footsteps leading up to my door, awareness of my surroundings, having a dark creature/figure perch at the end of my bed. My paralysis and associated fear last anywhere from one minute to several, and if I didn't wake myself thoroughly, upon falling back to sleep I would fall right back in to the paralyzed state. After awhile I learned how to manage my fear, but I tell you, that first night it happened I was just a teenager and this scared me to no end. Eventually my it was dog who caught on to theses episodes and she became very protective and would lay with me very close at night, and when she noticed I was beginning to try to move, moaning and showing discomfort, she would come and pounce on me and wake me up. Eventually these episodes were witnessed by my family, and they came to watch over me if I should fall asleep beside them or on the couch.
These episodes resolved miraculously on their own about a year ago. I can't think of any factors that contributed to this. But I am glad that they have stopped. I am glad I wasn't 'losing my mind'. Thank you to researchers like you who take the time to investigate this strange and terrifying experience.
Thank you
Danielle

Brains...
Dear all at Serendip
I have very much enjoyed looking around your website, especially your section on the brains of different animals. I am currently studying for my Masters in psychology, focussing my research on how educating children about their brains can aid their education. I can't find any copyright information on your website, so I wanted to ask whether I could use your picture of a frog's brain for my project. If successful, the resources created by my project will be available for everyone to use (in a non-profit capacity, of course!).
Many thanks

With regards to melatonin, and some notes on the 'Nocebo'-effect
I have just read Kathryn K. Ho's experiment using melatonin. The article in question gave a broad account of the effects of melatonin, before Kathryn went on to "conduct an experiment" where she, her parents and her younger siblings took melatonin for a single week and found no effects.
Melatonin has been shown to have several beneficial effects, including its use as an anti-cancer agent, and is certainly marketed to aid with sleep. However, it is strongly believed in the field of circadian research that melatonin is only useful as a supplement in the elderly (at least over 60). Kathryn rightly stated that melatonin production declines with age, and explains, at least in part, some of the sleep disruption that the elderly suffer from. It is logical that melatonin supplements would help those with a melatonin deficiency, in much the same way that someone with a perfectly balanced diet has no need of a multi-vitamin.
However, it would be interesting to know, if Kathryn and her parents (and maybe a larger sample population) took melatonin chronically every night, are they less at risk of developing certain cancers? (such as those associated with night-shift work: breast and colorectal cancers being named examples). There is some evidence now that melatonin may protect those at risk of developing neurodegenerative disease as well.
I find it interesting that Kathryn mentioned the 'Nocebo' effect. While it was probably the case that the melatonin was not doing anything for her as I assume she is not over the age of 60, there are recent studies to suggest that the Nocebo-effect is particularly relevant in chronic pain management. A very recent study (Irene Tracey's lab in Oxford, UK) connected patients to an IV drip of a well-known efficacious pain medication. They turned on the drip without telling the patients, and monitored their pain on a brain scan. The pain decreased somewhat without the patients knowing about the drug. When the doctors told the patients they were turning on the drip (even though it was already on), the pain decreased dramatically (remembering that the pain measured was not even reported actively by the patients). The doctors then told the patients that they were turning the drip off (even thought they left the drug running) and the pain measured in the patients was actually worse than before the experiment.
I hope that this highlights some of the importance of taking the right supplements for your age and diet (for example, often, taking vitamin C is a waste of money, as most of the drug is released into the urine anyway). Consult your GP about the right supplements for you. I'm not sure I would report melatonin as quite the wonder-drug that Walter Pierpaoli does in his pop-science book 'The Melatonin miracle:...' but there are almost certainly no detrimental effects of taking melatonin at night before sleep, so it can't do too much harm (except the hole in your wallet!) I also hope that you realise the importance of keeping an open mind with taking medications, as the placebo effect is physiologically very strong, as are the negative effects of feeling negative about a treatment! As a final note, I would like to say that there are some people who are 'larks' and some who are 'owls'; our circadian rhythms do not all run at the same time. All you can do for this in order to get more sleep is plan your day better and begin a regiment of trying to shift to the average 12pm-8am sleeping pattern. It is also vital for your body systems that you are exposed to a good amount of strong light (think sunny daylight) during the day - even going outside on a cloudy day is better than sitting at a computer screen all the time!

Rain On My Brain
Thoughts spinning like a vortex;
a tornado in my cerebral cortex
No damage was done to my intellect
attributed to how my skull protects
So no matter how life's weather
tries to drive me insane
Typhoons full of doom
are nothing more than rain on my brain
Responsible for my highest brain function
is my cerebrum
It's the largest part of my brain,
therefore making a spacious thought plain
for the falling of smart rain
The place of thought and action;
divided into four sections
The skies of men's minds
send out probes
to inquire of my lobes
like the production of crystals
from sweet sugar cane
Little liquid miracles
are the rain on my brain
Associated with reasoning is my frontal lobe
The realm of planning on my mental globe
Where speech, movement, and emotions abide
Solutions to problems this brain part provides
When movement, orientation, and recognition is vital
along with the ability to perceive stimuli
There is a portion of my brain that is not shy
which is a lobe called parietal
There is a section of my brain that is highly visual
Processing sight; it is the lobe called occipital
Interpreting the images of sight
like a translator in the mind's eye
and with it I see
all things vividly
Infinite photos in aquatic frames
are visions of rain falling on my brain
My temporal lobe speaks volumes
perceiving and recognizing the auditory
It is like the ears that inhabit my brain's columns
and holds captive experiences in my memory
It is auditory sensory
further speech capability
An acoustic receptor singing the refrains
of life's multiple songs
over and over all day long
Just like the melody of rain on my brain
My cerebral cortex is highly efficient
due to the wrinkles that increase its surface
Tons of neurons are held within it
making its gyrencephalization
or cortical folding relevant
My cerebrum has two halves
which are the right and left hemispheres
of my brain's potent mass
Each side functions differently
While the left hemisphere is associated with logistic abilities
the right hemisphere is all about creativity
These two hemispheres are divinely connected
by what is called the corpus callosum
a truly brilliant bundle of axons
There is a gray surface of the cerebrum
a little thicker than the average thumb
The white nerve fibers underneath
carry signals within the brain
and between the brain and body
To me, it is similar to the rain
carrying signals from high places to the ground
Almost as profound
as rain in drought drizzling on parched grain
or as phenomenal as rain on my brain
Man is considered an animal
classified as a mammal
Our animalistic instinct is not hid
when we don't keep a lid on our psychological id
And though at times we can be savage
our intelligence gives us an advantage
We have a neocortex
for processing information that is complex
Just like dolphins and primates
but superiorly, I hope you can relate
On the level of our exceptional DNA
by which we are both wild and tame
In an asphalt jungle and concrete rain forest
where rain falls upon our brains
Even though the cerebellum is known as the, "little brain,"
It is not small in concept by any means
It's the center of posture, balance, movement, and coordination
It is the mind's Mecca of regulation
And then there is the Limbic System
buried in the cerebrum
Known as the "emotional brain"
The thalamus, hypothalamus, amygdala, and hippocampus
it contains...
More than that it has
a much welcomed clashed
Guarding it from things insane
known as rain on the brain
Finally, there is the Brain Stem
underneath the Limbic System
Responsible for basic vital life functions
breathing, heartbeat, and blood pressure
are some of them
Made of the pons, medulla, and midbrain
And while poetry, wisdom, insight, and intellectuality
are not considered anatomical parts of the brain
they are and always will be
the refreshing ambiance in every season
Falling with reason
as rain upon our brains

Time to update your 'research', buddy.
This article is outdated and full of fallacies.
Sides of the Brain
Our names are Alexalis and Nicole, and we are doing a research project in our school. Our project is based on the brain. We have been studying the left and right side of the brain specifically. We have found a lot of information on each side, for example how the left hemisphere controls the right side of the body and the right hemisphere controls the left side of the body. We also did research on how the left and right side of the brain affect illusions.
On your website we found a lot of interesting facts on it and we were wondering if you could answer some questions:
- Which hemisphere of the brain is affected by illusions the most?
- What are some other differences between the hemispheres?
- How does illusions work ?
If any informative kits, we would really appreciate it. Thank You.
Frontal Lobe Cancer
Boyfriend is a former navy seal and was exposed to muster gas in first gulf war. I took him to the hospital other day because he was shaking. Was told he was having a grand mal seizure. His legs and feet sometimes gets numbs. He sometimes has short term memory problems, sometimes he does not "see" items that are right in front of him. We are looking for info about what is occurring as well as quality of life issues, given, that he was told he has a year or so to live. Any info appreciated
Life Science
Reply to woman whose boyfriend is sick with cancer: Recently reading about nutrition and although the information does not claim any cures for disease or cancer it has alot of eye-opening info. There is no date or address or publishing info on this book which is very unusual it only has Published by LIFE SCIENCE. It was bought this summer at a book fair and is actually six books in a volume called: Vol III: THE BASIC HEALTH LIBRARY it is in paper back style and old enough that some of the pages are yellowing around the edges. What it does stress is having a life style of eating Fruits and Vegetables, but not in our usual way of cooking but in their natural state, consumed raw. "Cooking destroys the nutritive values of food. It renders all foods INORGANIC in short order! Cooking destroys enzymes totally within moments of the application of heat. The constituent minerals (mineral salts) are broken down by heating into their inorganic components. Cooking coagulates proteins, renders them largely indigestible and de-aminizes the amino acids. It renders proteins inorganic---Cooking destroys co-enzymes (vitamins) though not as readily as it destoys enzymes and proteins." The book makes alot of good points and does refer to Rodale Press Inc for info on Organic Food directory. Some of the articles are penned by MD's. I myself am taking the suggestions of this info and eating raw fruit one kind maybe with alittle leaf lettuce or celery. (these two are compatable with fruit) no breakfast as the body has enough to go on from supper. So for lunch fruit fresh not cooked or canned or processed in any way and supper a large salad with bibb or romaine not iceberg, with 3 other fresh vegetables. It's worth a look, you learn things you didn't know before (unless u r already into it) They say not to use any condiments of any sort and to feel better on this way of eating with out any loss of nutrients, the carrot has 20 out of 24 amino acids! and celery has 13! It takes awhile for the body to adjust because of all the good things it gets into the body it starts passing out all the garbage, but after awhile your whole body and brain feels way better. Good luck don't forget we have a kind and loving heavenly Father who we can go to the throne of grace thru Jesus our Savior. The book also states that research said that Schizophrenia is a disease of protein imbalance in the brain and that witness the near 100% restoration to mental wholesomeness thru fasting. If you have not read Hulda Clark PHD book on cancer that would be worth getting also. Take care good luck! You can go to AmazingFacts.org for some really good scripture study lesson from the King James Bible press the free button!
Enjoy
Website offer easy, clear explanations. It is a joy to use as a study cortical plasticity. Thank you!
hello
i think your website is interesting. please fix the gramatical errors. this is a very large and well put together database and i appreciate your contribution to my knowledge.

perfect!
i cant even explain how great your article was in explaining what truly goes on in a "trip" internally and externally. This article must reach the masses of the youth, cause it explains both truth's of a trip. the amazing feeling and its horrible cost. I can honestly say this is the greatest article i've read about this subject. i hope one day this can be shown to all the youth to prevent this sad epidemic.
