Best Answer: The cerebral cortex is a structure within the brain that plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness.The human cerebral cortex is 2-4 mm (0.08-0.16 inches) thick.he bumps or ridges on the surface of the brain are called gyri (singular = gyrus). The folding of the cortex increases the cortical surface area.
