| What does the cerebellum control? | Balance, posture and movement |
| What processes does the medulla control? | Breathing, heart rate, arousal and sleep |
| State any 3 functions of the cerebral cortex | Centre of conscious thought Receives sensory information Coordinates voluntary movement Recalls memories Alters behaviour in the light of experience |
