    Abstract

    The developmental mechanisms underlying the subdivision of the neocortex into structurally and functionally distinct areas is central to our understanding of the development of human cognitive capacity and the pathogenesis of congenital disorders of higher brain functions. The protomap hypothesis suggests how the cytoarchitectonic pattern of the cerebral cortex may be generated by a combination of intrinsic and extrinsic influences during embryonic development. Although little is known about the genetic and molecular mechanisms underlying this individual and species-specific diversity of cellular and synaptic architecture, experimental manipulation of development in the primate embryo provides a glimpse into the cascade of cellular events involved in the control of cell numbers, specification of neuronal phenotypes, their apportions into cytoarchitectonic areas, and establishment of area-specific synaptic circuitry.
