The cerebral cortex plays a key role in memory, attention, perception, awareness, thought, language, and consciousness. The human cerebral cortex is 2 to 4 millimetres (0.079 to 0.157 in) thick. In large mammals, the cerebral cortex is folded, giving a much greater surface area in the confined volume of the skull.n the human brain more than two-thirds of the cerebral cortex is buried in the sulci. The cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries.
Functions of the brain. The brain is made up of several parts. Thought , voluntary movement , language, reasoning and perception are the major functions of the cerebral cortex. Cortex literally means bark (of a tree) in latin and is so termed because it is a sheet of tissue that makes up the outer layer of the brain.
