Document Summary

Devoted to processing a particular type of information. All have 3 things in common: topographic representation. Information/control from the body is mapped specific at an area in the cortex: contralateral control. Left side of the cortex controls the right side of the body, etc. Not sure why this happens: functional assignment of space. The more important/control an area on your body is, the more space (more representation) it gets in the cortex. Glucose is taken up by active areas, and since its radioactive, it can be tracked. Allows us to see how active an area is. Fine tune inputs from higher brain functions. Communicate between left and right hemisphere of the brain. Can be severed without too much trouble. Lack of dopamine in this area-> movement disorders (parkinson"s) Work on processes that terminate transmitter action. Does not allow movement (paralysis) but retains full consciousness. Caffeine (antagonist - blocks the release of neurotransmitter)
