Brodmann area 29, also known as granular retrolimbic area 29, is a cytoarchitecturally defined portion of the retrosplenial region of the cerebral cortex. Cytoarchitecture is the cellular composition of a bodily structure The retrosplenial region is a brain area and part of the Cingulate cortex. The cerebral cortex is a structure within the Brain that plays a key role in Memory, Attention, perceptual Awareness, Thought, In the human it is a narrow band located in the isthmus of cingulate gyrus. Cytoarchitecturally it is bounded internally by the ectosplenial area 26 and externally by the agranular retrolimbic area 30 (Brodmann-1909). Brodmann area 26 is the name for a small part of the Brain. Human In the human this area is called ectosplenial area 26. Brodmann area 30, also known as agranular retrolimbic area 30, is a subdivision of the cytoarchitecturally defined Retrosplenial region of the Cerebral
