WebbInvestigating the protomap hypothesis in the primate cerebral cortex; EPH A receptor expression The cerebral cortex, the seat of consciousness and intelligence, is mapped out into functional areas; for instance vision, movement control and language are controlled by distinct areas that are the same across normal individuals. WebbThis hypothesis is in agreement with the protomap hypothesis (the CP or SP areal destiny and size are determined early during fetal development). Our second hypothesis was that within periods there are significant differences in the relative growth rate (i.e., percent increase per GW) between neighboring regions.
