part of part of cingulate cortex Brodmann (1909) area 33 Brodmann area 33, pregenual SCTID:384788005 pregenual area 33 Wikipedia:Brodmann_area_33 Brodmann area 33, also known as pregenual area 33, is a subdivision of the cytoarchitecturally defined cingulate region of cerebral cortex. It is a narrow band located in the anterior cingulate gyrus adjacent to the supracallosal gyrus in the depth of the callosal sulcus, near the genu of the corpus callosum. Cytoarchitecturally it is bounded by the ventral anterior cingulate area 24 and the supracallosal gyrus (Brodmann-1909).
