rostral SMA proper

The term rostral SMA proper refers to an area located caudally on the mesial surface of the superior frontal gyrus in the human. It is defined on the basis of internal structure and function ( Matelli-2004 ). It is the more rostral of two parts of the SMA proper. It is activated when one imagines making a movement, such as a finger tap; observing another person make the same movement; or performing the movement repeatedly in a rhythm unassisted by external stimulation, as by a metronome. The other part of SMA proper is caudal SMA proper.

Also known as: area SMAr, rostral SMA proper

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'.
