Brodmann area 34

From Wikipedia, the free encyclopedia

This area is known as dorsal entorhinal area 34. It is a subdivision of the cytoarchitecturally defined hippocampal region of the human cerebral cortex. It is located in the entorhinal area on the medial aspect of the temporal lobe. It and the entorhinal area 28 together constitute approximately the entorhinal area (Brodmann-1909).

Some categorizations are approximations, and some Brodmann areas span gyri.
