Parts Of The Cerebral Cortex

The absence of clear anatomical boundaries has encouraged the development of numerous approaches to the subdivision of the cerebral cortex. The most commonly used map is based on Korbinian Brod-mann's parcellation of the cerebral hemispheres into more than 50 areas, each characterized by a specific pattern of neuronal density and lamination (Fig. 1). These cytoarchitectonic areas can be divided into five major functional zones: limbic, paralimbic, heteromodal association, unimodal association, and primary sensory-motor. The principal factual base for this functional categorization is derived from experiments in macaque monkeys. The homologies to the human brain have been inferred from comparative cytoarch-itectonics, electrophysiological recordings, functional imaging, and the behavioral effects of focal lesions.
