The term area 43 of Brodmann (guenon) refers to a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. Described but not labeled on the map of cortical areas in Brodmann-1909, it was regarded as cytoarchitecturally homologous to area 30 of Mauss-1908 in the guenon and area 43 of Brodmann (human) ( Brodmann-1909 ). The Vogts found no distinctive architectonic area of corresponding location the guenon ( Vogts-1919 ).
