The cerebral cortex is a structure within the brain that plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness. In dead, preserved brains, the outermost layer of the cerebrum has a grey color, hence the name 'grey matter'. Grey matter is formed by neurons and their unmyelinated fibers, whereas the white matter below the grey matter of the cortex is formed predominantly by myelinated axons interconnecting different regions of the central nervous system. The human cerebral cortex is 2–4 mm (0.08–0.16 inches) thick.

Birthplace of man's higher mental functions. It receives signals via the thalamus from all sense-organs and sends signals to the lower parts. Each neuron of its receptive areas represents some external feature and those of its motor areas represent movements of muscles.
