fMRI (Functional Magnetic Resonance Imaging) | Used to study functions using magnetic fields and radio waves to display oxygen laden areas. |
EEG (electroencephalogram) | Used to study brain function using amplified recordings of waves of electrical activity. Can be used to diagnose sleep or seizure disorders. |

Medulla | Sits at the base of the brain stem and controls heartbeat, breathing, swallowing, and circulation. |
Pons | Located above the medulla and control motor control and relays information to cerebellum. |
