Definition of Brachial Neuritis: Inflammation of nerves in the arm causing muscle weakness and pain.

Definition of Cervical Radiculopathy: A dysfunction of a nerve root of the cervical spine resulting from a disk herniation or an acute injury causing foraminal impringement of an existing nerve.

Definition of Pinched Nerve: A term for pain or impaired function of a nerve that is under pressure. It happens to nerves that control muscle movements or relay sensations to the brain.

The following sites are research literature references which will assist in my quest to better understand and develop a wholistic healing plan for a pinched nerve, cervical radiculopathy, and brachial neuritis.

brachial neuritis

pinched nerve

cervical radiculopathy

According to the authors, Miller, Pruitt, & McDonald., Acute Brachial Plexus Neuritis.( November,2000) & Gerald A Malanga., Cervical Radiculopathy.(April, 2005,the differentiation of Acute Brachial Plexus Neuritis from Cervical Radiculopathy may be problematic in some patients but can be distinguished by conducting a careful patient history and performing a neurologic examination separating the single nerve root finding in Cervical Radiculopathy from the "multliple nerve" findings of a brachial plexus lesion.

The authors further describe causes of cervical radiculopathy and pinched nerves are disk herniation, impingement of an existing nerve, buldging discs, or degenerative disc disease. Other causes include compression of a nerve at the elbow or wrist, a prolonged cramped posture, job injury, or a tumor.

Additionally, the authors report when a nerve gets pinched, the flow of tiny electrical charges begin to loose a healthy ability to transmit up and down the bundled nerve fibers that leave the spinal cord, eventually cease working, or die causing the skin to feel numbness or the ability to contract.

Suggested Medical Treatment

physical therapy,rehabilitation programs, non steriodal, anti-inflammatory drugs, aspirin, acetaminophen, use of ice/heat,medications,non operative treatment to reduce pain and inflammation, manual traction, cervical collar, cervical pillow, cervical epidural steroids, selective nerve blocks, and acupunture.

Implications for this Author's Scientific Journey

Internet use has proven extremely useful in my quest to create a new set of observations in the storytelling of symptons characteristic of a pinched nerve, cervical radiculopathy, and brachial plexus neuritis.

The sites and articles provided succinct similarities and differences of a multi-sympton nerve condition existent in my health life.

Further, the internet research provided clear definition, explanation, and information regarding a topic of interest and multiple treatment plans to assist in resolution of my health issue.

The ability to research the aforementioned conditions has enabled me to make informed decisions. My physician and I will collabortively develop a wholistic plan for healing brachial neuritis, cervical radiculopathy, and a pinched nerve.

robot brain evolution

I submitted my final project html, but I don't see where they are going to be available for viewing. I hope a link is added so I read them all. Since a couple of people asked me to post the code from my project so they could fiddle with the robots, I posted my final project page (with links to the code) in my public folder. Hopefully, there's all the info you'd need to run it. Happy evolving!

does emergence matter?

Earlier on in the semester, doug wrote "I think the study of "emergence" can be seen as a luxury topic. People may see it as non-critical, and do not see it as a field of inquiry that will immediately solve real problems. (I beg to differ). I suspect that the few women and other underrepresented groups are attracted, first, to the major topics, and slowly diffuse into "fringe" areas." This sentiment rang all too true to me. Emergence may attempt to explain and describe the physical world, but constructing computer models does not feel like solving everyday problems. It feels like playing games.

Neural networks to make emergent simulations more efficient?

I wrote a short essay for a related class about how neural networks might (or might not) be able to help speed up emergent simulations, and I may try and test this idea in my tree simulation project. Here is my essay if you are interested; please let me know what you think!

Assessments of Emergence

Throughout this course, I've found one aspect of our discussions and readings to be somewhat troubling. There is a tendency proclaim emergence as a penultimate field, emergent phenomenon as universal and terribly important...in short, emergence as not just a new kind of science but the coming messiah of science. It could just be that the field, in particular the content matter, is inherently of a universal and penetrating sort. So if emergence itself claims to be the end-all, be all of reality, then our conversations and emergent literature should similarly describe it as such. I think this is true to a certain extent. In my eyes, however, there is also a some aggrandizing in our conversations and the literature.

Emergence talk at Haverford

Dr. Ursula Goodenough (Professor of Biology, Washington University, St. Louis, MO, author of The Sacred Depths of Nature): "EMERGENCE: NATURE'S MODE OF CREATIVITY" She'll be speaking as part of a larger forum on Saturday, April 8th from 1PM-5PM in Sharpless Auditorium Ursula Goodenough is currently Professor of Biology at Washington University in St. Louis MO. She was educated at Radcliffe and Barnard Colleges (B.A. Zoology, 1963), Columbia University (M.A. Zoology, 1965) and Harvard University (Ph.D. Biology, 1969), did 2 years of postdoctoral at Harvard, and was Assistant and Associate Professor of Biology at Harvard from 1971-1978 before moving to Washington University.

Book commentaries

Are now available (at least some of them).

Potential for computers to be as intelligent as humans

Here is the paper I mentioned in class during our discussion of whether or not computers will ever be able to achieve behavioral complexity comparable to that of humans: When will computer hardware match the human brain, by Hans Moravec in 1997. "This paper describes how the performance of AI machines tends to improve at the same pace that AI researchers get access to faster hardware. The processing power and memory capacity necessary to match general intellectual performance of the human brain are estimated. Based on extrapolation of past trends and on examination of technologies under development, it is predicted that the required hardware will be available in cheap machines in the 2020s." That soon? It sounds a little bit crazy, but the general idea is pretty solid, in my opinion: that eventually, in the not-too-distant future (maybe not quite so soon as 2022) computers will easily rival or surpass human intelligence. I would be interested to know whether or not Moravec can convince Professor Grobstein.

Cockroach Behavior

I found an article on Slashdot today about the decision making patterns used by cockroaches. It echoes many of the same ideas in the book I read for my project (Emergence, by Steven Johnson). It's a very short article and it demonstrates how cockroach/ant/etc colonies can function without a centralized authority dictating the behavior of the group.
