ventral premotor cortex
Acronym:
The term ventral premotor cortex refers to one of three areas of premotor cortex defined on the basis of internal structure, connections and function in the human and the macaque ( Matelli-2004 ). In the human it is located in the caudal parts of the inferior frontal gyrus including portions of the triangular part of the inferior frontal gyrus and the opercular part of the inferior frontal gyrus. It is identified with the inferior part of area 6 of Brodmann (human), area 44 of Brodmann and possibly area 45 of Brodmann. In the macaque the ventral premotor cortex is located in the inferior portion of the precentral gyrus. It is identified with the inferior part of area 6 of Brodmann (guenon) that is not occupied by primary motor cortex, and it is composed of two parts: the rostral part of ventral premotor cortex (PMVr) and the caudal part of ventral premotor cortex (PMVc). These structures are involved in: 1) the motor aspect of speech,as Broca's area in the human; 2) hand movements in both human and macaque; and 3) recognition of hand movements made by another individual ( mirror function ) in both species. The other components of premotor cortex are the dorsal premotor cortex and the mesial premotor cortex.
