From Wikipedia, the free encyclopedia
In the human subcentral area 43 is a subdivision of the cytoarchitecturally defined postcentral region of cerebral cortex. It occupies the postcentral gyrus and the precentral gyrus between the ventrolateral extreme of the central sulcus and the depth of the lateral sulcus at the insula. Its rostral and caudal borders are approximated by the anterior subcentral sulcus (H) and the posterior subcentral sulcus respectively. Cytoarchitecturally it is bounded rostrally by the agranular frontal area 6 and caudally, for the most part, by the caudal postcentral area 2 and the supramarginal area 40 (H) (Brodmann-1909). One of the functions is as the "gustatory cortical area".
[edit] Guenon
Brodmann area 43 is a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. Described but not labeled on the map of cortical areas in Brodmann-1909, it was regarded as cytoarchitecturally homologous to area 30 of Mauss-1908 in the guenon and subcentral area 43 of the human (Brodmann-1909). The Vogts found no distinctive architectonic area of corresponding location in the guenon (Vogts-1919).
