===Types of cortex===

Based on the differences in [[laminar organization]] the cerebral cortex can be classified into two types, the large area of [[neocortex]] which has six cell layers, and the much smaller area of [[allocortex]] that has three or four layers:<ref name="Strominger"/>

* The neocortex is also known as the isocortex or neopallium and is the part of the mature cerebral cortex with six distinct layers. Examples of neocortical areas include the granular [[primary motor cortex]], and the striate [[primary visual cortex]]. The neocortex has two subtypes, the ''true isocortex'' and the [[proisocortex]] which is a transitional region between the isocortex and the regions of the periallocortex.
* The allocortex is the part of the cerebral cortex with three or four layers, and has three subtypes, the [[paleocortex]] with three cortical laminae, the [[archicortex]] which has four or five, and a transitional area adjacent to the allocortex, the [[periallocortex]]. Examples of allocortex are the [[olfactory cortex]] and the [[hippocampus]].

There is a transitional area between the neocortex and the allocortex called the [[paralimbic cortex]], where layers 2, 3 and 4 are merged. This area incorporates the proisocortex of the neocortex and the periallocortex of the allocortex. In addition, the cerebral cortex may be classified into four [[Lobes of the brain|lobes]]: the [[frontal lobe]], [[temporal lobe]], the [[parietal lobe]], and the [[occipital lobe]], named from their overlying bones of the skull.
