WebbAllocortex. The allocortex or heterogenetic cortex, and neocortex are the two types of cerebral cortex in the brain. The allocortex is the much smaller area of cortex taking up just 10%; the neocortex takes up the remaining 90%. [1] It is characterized by having just three or four cortical layers, in contrast with the six layers of the neocortex.
