Cortical Column - Mammalian Cerebral Cortex

Mammalian Cerebral Cortex

The mammalian cerebral cortex, the grey matter encapsulating the white matter, is composed of layers. The human cortex is roughly 2.4 mm thick. The number of layers is the same in all mammals, but varies throughout the cortex. In the neocortex 6 layers can be recognized although many regions lack one or more layers, fewer layers are present in the archipallium and the paleopallium.
