The term area 3 of Vogts refers to an area of the cerebral cortex defined on the basis of myeloarchitecture and cytoarchitecture in the guenon. It consists of two subdivisions, area 3a of Vogts and area 3b of Vogts. The authors regarded it as cytoarchitecturally and myeloarchitecturally the same as area 3 of Brodmann (guenon), though Brodmann drew it on the surface of the postcentral gyrus rather than in the caudal bank of the central sulcus ( Vogts-1919 ).
