ventral secondary motor cortex

The term ventral secondary motor 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.

Also known as: ventral premotor cortex, area PMV, ventral secondary motor cortex

Models Where It Appears

Topographic Model of Human Cerebral Cortex

The topographic model of human cerebral cortex is a closed partitive hierarchical model of cerebral cortical structure in the human. The cerebral cortex is segmented on the basis of internal structure, connectivity, and/or functions of cortical areas. It is designed to update the comprehensive early twentieth century parcellations of Brodmann and of von Economo and Koskinas and their successors. A work in progress, it integrates the most authoritative, comprehensive, and recent parcellations and nomenclatures from peer-reviewed publications and neuroanatomical texts. For an equivalent model in the rodent, Search BrainInfo for ' Functional CNS Model - Rat '. This segmentation of the human cerebral cortex, based on a combination of internal structure, connectivity, and function, complements the classical segmentation of the cerebral cortex into lobes, lobules, and gyri based on sulcal patterns: For the classical segmentation, see ' cerebral cortex ' and click 'Locus in Brain Hierarchy'.
