Premotor Cortex

@@Home -> BiologicalLifeResearch -> BrainCenterNC_PMC

This page covers biological details of component group Premotor Cortex. Component group is part of aHuman target integrated biological model.

Top-down path to center: Cortex -> Anterior Lobe (NC.LOBE.ANT) -> Premotor Cortex (NC.PMC) (see Mind Maps)
Function: Selection of appropriate motor plans for voluntary movements
