Document Summary

Parietal lobe- paying attention, not only one job (visual, hearing, touch, etc) Studies done on monkeys help with knowledge of human brain. Macaque (rhesus monkey) studied most because of its similarity of the brain with humans. Right-handed 95% chance language area is in left hemisphere. We need the cortical tissues to be bundled up to be able to fit into our head. White matter: myelin-bound neurons, decreases with ms or aging. No relationship between brain size and cognitive abilities. Gov"t agencies used these wow, much surprise. Had about as much credibility as handwriting analysis. Made a small lesion in different parts of a rat brain. Created the idea that there was an action potential. Key to learning about motor and sensory cortices. Can join forces to see if one part of the brain affects another part of the brain. Broken part may not be direct reason for something going wrong.
