Anatomical terms of neuroanatomy

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.[1] Cytoarchitecturally it is bounded by the ventral anterior cingulate area 24 and the supracallosal gyrus (Brodmann-1909). The pregenual area 33 is heavily involved in emotions, especially happy emotions.[2][3]
