The term area PEp of Bonin refers to a subdivision of the parietal lobe of the macaque defined on the basis of cytoarchitecture. It lies caudal to area PEm of Bonin. It is identical to area PEm except for a lack of the very large pyramidal cells seen in the internal pyramidal layer (V) of PEm. The authors labeled it simply PE in their cortical map. They regarded it as a part of area 7 of Brodmann (guenon); the other part was distinguished as area PG of Bonin ( Bonin-1947 ).
