Comparative Neuroanatomy and Intelligence

Comparative Neuroanatomy and Intelligence


Brains inside Space inside Brain


Have you ever wondered what makes us humans different from, say, a rat? Have you ever wanted to see a cerebellum up close and personal? Have you ever looked at a frog and thought to yourself - hmmm, I wonder if he has neocortex? Have you ever wondered how intelligence is defined?

If so (or even if not!), you have come to the right place. While no "answers" will be given, we will explore together the intricacies and wonder of the brain. We will ponder questions about cognition and attempt to link brain to behavior.

You need not have any previous science experience to explore this website or participate in the thought exercises within!

This exhibit is organized into four main parts, and if you ever find yourself lost you can use the index on the left to guide you back:

  1. Comparative Brain Sizes and Body Sizes of Various Different Animals

  2. Details (and Slicing) of Brains

  3. Neurons and the Nervous System

  4. The Question of Intelligence

First, you may ask why are we studying comparative neuroanatomy? What is the use? Let's think about that... click here for a discussion of the relevance of this type of study.

eating raw cat...thats the cats meow!

Pardon the really bad pun (P-U), its affects nothing. Its pure protein, fat and ligaments. All animals, if you watch closely are either predator or prey. Cats are prey to bigger animals, and predators to rodents, horses are prey, dogs, mostly predators..I have it all. I watched them carefully since one of my hobby is anthropology. They care, they cry, they get hungry, they get angry. They have emotion, contrary to popular belief

How does eating raw cat affect your brains?

brain systems & behaviur

I'm 83yrs and having a problem with my 79yrs wife and 49yrs son who seem to be in what is described as a co-dependent relationship. This relationship doesn't so much exclude me and others as define us emotionally in a way that results in exclusion. Their defining of us seems less based on fact and more on imagined subjectivity of fact. Example: My son had a device looking like a plyers about 15" long and a 'C' shaped bit. He calmly speculated what it was made to do. I suggested frivilously that it might be used to circumsize horses. He immediatly went into a rage, among other things approaching and threatening to brain me with the device. (I later remembered the device is used to leaver nails from horseshoes.)
I became aware many years ago my body needs to be used or it begins to atrophy, hence a continued exercise program. I'm wondering if the brain also needs exercising and in some cases will demand that exercising spontaneously if it isn't provided in the environment. In my son's case I'm wondering about his limbic system needing a workout that isn't available in his present life-style and used to be. Some people seems to get an emotional workout vicariously in our passive culture by reading or watching emotional events such as sports. Some people are satisfied with water; some prefer alcohol.
This highly emotional response on the part of my son isn't limited to me. It has happened so often with other family members excluding his mother that they avoid him and with friends such that he no longer has any.
