mesial secondary motor cortex

The term mesial secondary motor cortex refers to one of three areas of premotor cortex defined on the basis of internal structure, neurochemistry, connections and function in the human and the macaque ( Matelli-2004 ). In both species it is located on the mesial surface of the rostral part of the precentral gyrus and caudal part of the superior frontal gyrus. It is associated with the mesial part of area 6a of Vogts (mesial part of area 6 of Brodmann). It is divided into two parts: presupplementary motor area, which is involved in the sequencing of movements and supplementary motor area proper, which is involved in the execution of movements. The other components of premotor cortex are the dorsal premotor cortex and the ventral premotor cortex.

Also known as: mesial premotor cortex, supplementary motor area, mesial area 6, mesial premotor area, mesial 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'.
