Document Summary
*sensory cortex informs the motor cortex of the event occurring: basal ganglia (under frontal cortex) = produce appropriate amount of force, cerebellum = regulate timing & correct errors. The neocortex & initiation of movement: posterior sensory cortex: Specify movement goals & send info to : prefrontal cortex. Indirect routes = movement requiring conscious control: premotor cortex. Recognize movement of others & select similar/different actions: motor cortex. Executes/produces specific, appropriate movement: movement hierarchy, simple : controlled by motor cortex (push a button, sequence : additionally controlled by premotor cortex, complex: controlled by prefrontal, temporal, parietal cortex (maze) Identifying the motor cortex with the use of electrical stimulation: wilder penfield. Used brief electrical impulses to map cortices of human patients (about to undergo neurosurgery) Most movements triggered by stimulation of precentral gyrus (primary motor cortex) Movement can be produced by stimulating dorsal part of premotor cortex (supplementary motor cortex)
