Brodmann area 29, also known as granular retrolimbic area 29 or granular retrosplenial cortex, is a
cytoarchitecturally defined portion of the
retrosplenial region of the
cerebral cortex
The cerebral cortex, also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. It is the largest site of Neuron, neural integration in the central nervous system, and plays ...
. 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 has this to say about area 29, amongst his other comments on it:
"An unusual regression of layer II together with layer III is found in the granular retrosplenial cortex, illustrated in Figures 38 to 41 for four different animals. Here, in addition to the regression of layers II and III, there is fusion of the original layers V and VI and at the same time an isolated massive increase of the inner granular layer, that is particularly prominent in Figures 38 and 39;..."
