The cerebellum is responsible for coordinating body movements during activities such as catching a ball, by aligning the movements of the eyes, head, and hands.
The part of the brain that is responsible for coordination during movement, such as catching a ball and coordinating head and eye movement, is the cerebellum. The cerebellum, often referred to as the "little brain", is located below the cerebrum and behind the brainstem. It plays a crucial role in balance, movement, and learning new motor tasks. When a person catches a ball, the cerebellum works to help coherently align the movements of the eyes and head with the hands to perform the catch efficiently and accurately.
