PSYB65H3 Chapter Notes - Chapter 9: Striatum, Supplementary Motor Area, Premotor Cortex
Document Summary
Psyb65 chapter 9: note fig 9. 4, 9. 11, 9. 15 not included print out and include in notes* can consider the entire nervous system to be the motor system = functions to move the body. Four general regions of the neocortex produce our skilled movements. Posterior cortex specify movement goals and send information to the prefrontal cortex by a number of routes. Indirect routes through the temporal cortex are used for movements requiring conscious control. Premotor cortex contain a repertoire of movements a lexicon that allows it to recognize the movement of others and select similar or different actions = lie anterior to motor cortex. Brodmann"s area 6 = which includes a ventral region and a dorsal region called the supplementary motor cortex. Because the body is symmetrical, each hemisphere contains an almost mirror- image representation of this homunculus homunculus has very large hands with an especially large thumb. It also has very large lips and a large tongue.
