cerebral cortex JUST WRITTEN FOR YOU

/səˈriːbrəl ˈkɔːrtɪks/ · ce·re·bral cor·tex
noun
  1. The grey, folded, outermost layer of the cerebrum that is responsible for higher brain processes such as sensation, voluntary muscle movement, thought, reasoning, and memory. The neurosurgeon examined the patient's cerebral cortex for signs of traumatic injury.
Did you know? The term ‘cortex’ derives from the Latin word for ‘bark’, because early anatomists thought the brain’s outer layer resembled the bark of a tree.
