<P> Within the brain , the autonomic nervous system is regulated by the hypothalamus . Autonomic functions include control of respiration , cardiac regulation ( the cardiac control center ) , vasomotor activity ( the vasomotor center ) , and certain reflex actions such as coughing , sneezing , swallowing and vomiting . Those are then subdivided into other areas and are also linked to ANS subsystems and nervous systems external to the brain . The hypothalamus , just above the brain stem , acts as an integrator for autonomic functions , receiving ANS regulatory input from the limbic system to do so . </P>
