The brain controls "lower", unconscious activities such as heartbeat, respiration, and digestion - these are known as autonomic functions. The brain also controls "higher" order, conscious activities, such as thought, reasoning, and abstraction. The human brain is more capable of these higher order activities than any other species' brain.
