Cerebral Cortex: The cerebral cortex covers the outer portion (1.5mm to 5mm) of the cerebrum. It is the layer of the brain often referred to as gray matter. The cortex (thin layer of tissue) is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white.he cortex also covers the cerebellum. The cerebrum is the most highly developed part of the human brain and is responsible for thinking, perceiving, producing and understanding language. Most information processing occurs in the cerebral cortex.
About 90% of all the brain s neurons are located in the cerebral cortex, mainly in the grey matter , which makes up the surface regions of the cerebral cortex, while the inner white matter consists mainly of myelinated axons, over 170,000 km of them.he cerebrum (or forebrain), which makes up 75% of the brain by volume and 85% by weight, is divided by a large groove, known as the longitudinal fissure, into two distinct hemispheres.
