 The histological structure of Area 43 was initially described by Korbinian Brodmann, but it was not labeled on his map of cortical areas.In the human "subcentral area 43", a sub area of the cytoarchitecture is defined in the postcentral region of the cerebral cortex.It occupies the postcentral gyrus, which is between the ventrolateral extreme of the central sulcus and the depth of the lateral sulcus, at the insula.
