The cerebral cortex plays a major role in all of the following except d. circadian rhythm
The cerebrum is split into the left and right hemispheres, while the cerebral cortex makes up the outer layer of the brain and is comprised of gray matter. Gray matter is made up of unmyelinated neurons.
The cerebral cortex is described as having motor, sensory and association areas, and is involved in thought, memory, perception, awareness, and language. Overall, it is associated with voluntary movement, thus the circadian rhythm, involved in homeostasis and the autonomic nervous system, is unrelated to its function.
