Document Summary
Motions vary with objects and events: 3 fundamental problems. Multiple effector sets to accomplish a goal. How does the brain figure out in which order to do things. Can prepare for one response before the stimulus. Its not one stimulus leads to one response, one stimulus leads to one response: da brain. Tools:directions: coronal - study lateral aspects, horizontal - good for studying layers of brain (top to bottom, sagittal - focus on specific areas in certain areas on left and/or right area (side to side) Primitive responses are handled in the spine. Arousal, tuning, emotions etc: cerebral cortex. The big cheese: cerebellum talks to brain stem and cortex (connected to both) Was not aware of 3 fundamental problems. Thought all brain structure developed to maximize processing of reflexes. Connects outer surface of body to spinal cord. Cortex connects through tracts down through spinal cord to surface of muscles. Connect left side of brain to left side of body.
