Abstract
A prominent feature in the evolution of neocortex in higher mammals is the appearance of multiple areas of cortex which function in the hierarchal and parallel processing of sensory input and motor output. One way each of these areas can be identified is by their characteristic and specific patterns of connectivity with cortical and subcortical areas. How axonal growth cones from neurons in the thalamus and other cortical areas recognize which presumptive cortical area is an appropriate target and enter it to form connections is not known. In the cat, the earliest born neurons of the neocortex form a transient structure termed the “subplate” (Luskin and Shatz,’85) which has been reported be necessary to allow thalamocortical afferents to enter the cortical plate of area 17 (Ghosh et al.’90).
