ABSTRACT
The classical cytoarchitectonic maps of the human cerebral cortex published by Brodmann (1909), Campbell (1905), Elliot Smith (1907), von Economo and Koskinas (1925) and the Vogts (Vogt and Vogt, 1919) have recently gained considerable attention, since they present mandatory structural data for the microanatomical interpretation of functional imaging data. These maps, however, do not fulfil the requirements of an anatomical reference system for functional human brain mapping. For instance, they present only schematic, simplified drawings of a single, individual brain or hemisphere in a two-dimensional view without any descriptions of the intersubject variability of cortical architecture. The same is
maps differ between each other with respect to the number, location and extent of cortical areas (Zilles, 1990).
