Hypothalamus: The hypothalamus lies at the base of the cerebrum. It controls the sleep and wake cycle of the body. It also controls the urge to eat and drink.
Cerebellum: Cerebellum lies below the cerebrum and at the back of the whole structure. It is responsible for the voluntary actions of the body and helps in maintaining the equilibrium of the body.
