The brainstem is the corridor for information transmission within the body between the cerebrum, the cerebellum, and the rest of the body.
The brain stem controls many important biological processes in the human body, including regulating the heartbeat, breathing, sleeping, and eating.
The nerve pathways coming from the body towards the brain stem carry nerve impulses that transmit sensory pathways such as the sensation of temperature, pain, and pressure.
The brainstem has integrative functions including control of the cardiovascular system, control of the respiratory system, control of pain sensitivity, alertness, and awareness.
