Document Summary
Connection of different brains to complexity of thought and behaviors. Difference in complexity not due to variation in size, but comparison of brain weight relative to body weight. Large proportion of brain devoted to cortex complex behaviors. No one-to-one brain mapping (each function corresponds to one area) System in which some parts work together for a function and are more crucial for some behavior/thought than other areas. Can"t say that one person can"t perform an action just because a particular area of brain is damaged. Electrical stimulation action potential as basis for communication. Animals choose option for stimulation of these centers over food even if they have to endure pain to get to pleasure. Patient turns electrode on when they need it. Initially used to treat parkinson"s patients who could no longer take medication. Overall successful, so used to treat other diseases.
