Brodmann area 33
Encyclopedia
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
. Cytoarchitecturally it is bounded by the ventral anterior cingulate area 24 and the supracallosal gyrus
(Brodmann-1909).
Cerebral cortex
The cerebral cortex is a sheet of neural tissue that is outermost to the cerebrum of the mammalian brain. It plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness. It is constituted of up to six horizontal layers, each of which has a different...

Supracallosal gyrus
The supracallosal gyrus consists of a thin layer of grey matter in contact with the dorsal surface of the corpus callosum and continuous laterally with the grey matter of the cingulate gyrus....
