Document Summary

Premotor ( before motor ) and supplementary motor cortex (secondary motor cortex) Frontal lobe described in terms of planar perspectives. Executive functions: controlling cognitive processes so appropriate movements are chosen to be performed at the right time in the right place. The target for the projections of the dorsomedial nucleus of the thalamus. Motor functions enable the organism and underlie the execution of all motivational goals. In many ways the brain"s goal-initiated regulation of the motor system determines the emotional and social well-being of the organism. Goal-directed and improve with practice as result of feed-forward (anticipatory) and feedback mechanisms. Active during both preparation of a movement by self and while watching someone else perform a similar movement. Major point of convergence for cortical sensorimotor information. Critical for learning motor skills, organizing sequences of movement, automatic behaviors, and new habits. Diseases that affect the bg are notable by virtue of the dramatic change in motor performance.
