Document Summary
Foundations in neuroanatomy: the geography of the mind. Human brain most complex structure in the universe (includes genetic code, computer central processing units, molecules) Volume of human brain 1300 cm^3 or 1300 cc. Width of a nerve cell 10 m or 10 x 10^-6 m. 100 billion nerve cells (10^11: scientific notation, 100 = 10^2, 1000 = 10^3, 10 = 10^1. ~10^3-10^4 connections per neuron: 10^11 x 10^3 = 10^14. Your brains are pretty identical: differences are represented in unique differences in connectivity. Our receptors are not able to see many electromagnetic fields (ex. infrared ad ultraviolet) Of all the information you are experiencing, you are only aware of a small amount of it. If you understand the hepatocyte, you understand liver function. If you understand the nephron, you understand kidney function. If you understand the neuron, you do not understand brain function (yet) Dopamine is released when you see a pleasurable stimulus.
