It is also involved in balance and in the processing of both visual and auditory information: cerebellum contains neurons that coordinate muscular activity. Part of the brain that controls balance and muscular coordination. One of the most primitive brain structures. Accounts for 10. 5% of the adult brain weight. Governs balance and is involved in general motor behavior and coordination. Brain lesions in the cerebellum can cause irregular and jerky movements, tremors, and impairment of balance and of gait.
