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. The pregenual area 33 is heavily involved in emotions, especially happy emotions.
