cerebral cortex

n.
The extensive outer layer of gray matter of the cerebral hemispheres, largely responsible for higher brain functions, including sensation, voluntary muscle movement, thought, reasoning, and memory.

cere′bral cor′tex


n.
the outer layer of gray matter in the cerebrum associated with the higher brain functions, as voluntary movement, sensory perception, and learning.

cerebral cortex

The outer layer of gray matter that covers the cerebral hemispheres in the brain of many vertebrate animals and is composed of folds of nerve cells and fibers. The cerebral cortex is responsible for higher functions of the nervous system, including voluntary activity and the senses of hearing, vision, and touch. In humans, it is the center of learning, language, and memory.

cerebral cortex

The cerebrum’s thin outer layer of gray matter. It consists of neurons’ cell bodies and dendrites.
