Brodmann area 6

Brodmann area 6 is a cytoarchitecturally defined portion of the frontal lobe of the guenon. Brodmann-1909 regarded it as topographically and cytoarchitecturally homologous to the human agranular frontal area 6 and noted that, in the monkey, area 4 is larger than area 6, whereas, in the human, area 6 is larger than area 4. Distinctive features (Brodmann-1905): It is thick relative to other cortical areas; the transition from cortex to subcortical white matter is gradual; cell layers are indistinct; and the internal granular layer (IV) is absent. ==Image==
