Allocortex

Any of the regions of the cerebral cortex that have fewer cell layers than the isocortex, especially the olfactory cortex and the hippocampus. Also called heterotypic cortex.

The phylogenetically older part of the cerebral cortex and includes the cortex of the paleopallium and the archipallium. The newer part of the cortex is the neocortex or isocortex.

The allocortex is a part of the cerebral cortex characterized by fewer cell layers than the isocortex, or 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 input

The allocortex is also referred to as the "heterotypic cortex."
