Preferred Label : Brodmann (1909) area 6;
Uberon definition : Brodmann area 6, or BA6, is part of the frontal cortex in the human brain. Situated
just anterior to the primary motor cortex, it is composed of the premotor cortex and,
medially, the supplementary motor area, or SMA. This large area of the frontal cortex
is believed to play a role in the planning of complex, coordinated movements. Brodmann
area 6 is also called agranular frontal area 6 in humans because it lacks an internal
granular cortical layer (layer IV). It is a subdivision of the cytoarchitecturally
defined precentral region of cerebral cortex. In the human brain, it is located on
the portions of the precentral gyrus that are not occupied by the gigantopyramidal
area 4; furthermore, BA6 extends onto the caudal portions of the superior frontal
and middle frontal gyri. It extends from the cingulate sulcus on the medial aspect
of the hemisphere to the lateral sulcus on the lateral aspect. It is bounded rostrally
by the granular frontal region and caudally by the gigantopyramidal area 4 (Brodmann,
1909).;
