The term Vogts' areas refers to a classification of human cerebral cortex into more than 200 subdivisions based on cytoarchitecture and myeloarchitecture by Cecile and Oskar Vogt ( Carpenter-1983 ). It also refers to a classification of lateral and dorsal cortical areas of the frontal lobe, the parietal lobe and the lateral temporal lobe of the guenon (Cercopithecus) into some 36 areas ( Vogts-1919 ). Cecile and Oskar Vogt worked in the same institute as Brodmann and Mauss ( Brodmann-1905, Brodmann-1909, Mauss-1908 ). Their classification scheme for cortical areas in the guenon was an extension of the segmentations produced by those authors. While the maps of Brodmann and Mauss were based on three brain specimens each, the Vogts' study included some 100 specimens. Their illustration of cortical areas differed from those of Brodmann in that they subdivided many of Brodmann's areas, they did not draw boundaries hidden in sulci on the surface of the brain, and their report included an extensive description of the character of the transitions from one cortical area to another.
