The term
area 8a of Brodmann refers to an area located on the posterior "lip" of the
middle frontal gyrus that was defined on the basis of cytoarchitecture in the
guenon. In comparison with
area 8 of Brodmann (
guenon),
area 8a showed more pronounced layers of large pyramidal cells (layer IIIb in the
external pyramidal layer (III)) and of ganglion cells in the
internal pyramidal layer (V); the
internal granular layer (IV) was less pronounced. The internal structure of the area was illustrated in
Brodmann-1905. It was not mentioned or illustrated in the map of
