In humans, the cerebellum is a peach-sized, lobed structure located near the base of the brain. It is primarily involved in controlling bodily movement and the development and recollection of physical skills. In order to function properly, the cerebellum must receive information from several parts of the body, such as the eyes, the ears, the limbs, and the cerebrum. The cerebellum, the name of which means “little brain” in Latin, then coordinates all incoming information and makes fine adjustments in motion at the subconscious level. This is how good tennis players can meet the ball in the right place at the right time and return it with appropriate force without having to willfully consider the motions of their muscles.
