The term area 3 of Brodmann (human) refers to a subdivision of the cytoarchitecturally defined postcentral region of cerebral cortex. In the human it is located primarily in the rostral portion of the postcentral gyrus including the caudal bank of the central sulcus. At either end of the sulcus it can extend beyond the depth of the sulcus into the precentral gyrus. Cytoarchitecturally it is bounded rostrally by the area 4 of Brodmann (human) and caudally by the area 1 of Brodmann (human) ( Brodmann-1909 ).
