The cerebellum is a portion of the brain that is responsible for fine motor movements including posture, balance, motor learning (like learning to kick a ball), and speech. Located at the base of the skull, the cerebellum contains about half of all neurons in the brain, though it represents only 10% of the volume. Losing partial function due to injury or disease isn’t completely unprecedented, though lacking a cerebellum from birth is exceedingly rare.
