Leokris [45]

Answer: Difficulty with communication

Explanation: The cerebral cortex is the thin layer of the brain that covers the outer portion (1.6mm to 5mm) of the cerebrum. It is covered by the meninges and often referred to as gray thing . The cortex is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white. The cortex also covers the cerebellum.

The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and <em><u>speech</u></em>, resulting in smooth and balanced muscular activity
