The term prefronto-dependent motor areas refers to a composite structure in the precentral gyrus defined on the basis of connectivity in the macaque ( Matelli-2004 ). It consists of areas in the rostral part of the gyrus that receive their primary input from the prefrontal cortex (macaque): presupplementary motor area (F6) and the rostral part of dorsal premotor cortex (F7). It is contrasted to the parieto-dependent motor areas, which receive primary input from the parietal lobe.
