| What does the cerebellum do? | Receives information from the muscles, skin, joints, ears and eyes and motor cortex about our movement. It then coordinates movement and may be involved with some forms of learning. |
| What does the brain stem do? | Maintains blood pressure, heart rate and breathing rate. contains the reticular formation |
