Brodmann (1909), a student of Cécile Vogt-Mugnier and Oskar Vogt, who worked on cercopithecus (and not much in human Bailey and von Bonin), elaborated a system of numeration that had unfortunately no typological logics (1, 2 and 3 are sensory, 4 is motor, 5 is parietal, 6 is premotor and 7 is again parietal!).
