noun

1. the furrowed outer layer of gray matter in the cerebrum of the brain, associated with higher brain functions such as voluntary movement, learning, memory, coordination of sensory information, and the expression of individuality.

cerebral cortex Scientific  

1. The layer of gray matter in vertebrates that covers the cerebral hemispheres and is composed of folds of neurons and axons. The cerebral cortex is responsible for higher functions of the nervous system, including voluntary muscle activity and learning, language, and memory.
