The allocortex (also known as heterogenetic cortex) is a part of the cerebral cortex characterized by fewer cell layers than the neocortex (i.e. fewer than six). The specific regions of the brain normally described as part of the allocortex are: the olfactory cortex which mediates olfaction the hippocampus which mediates limbic inputAllocortex is heterogenetic cortex because during development it never has the six-layered architecture of homogenetic neocortex.
