Cerebellum

Controls and coordinates involuntary, rapid, fine motor movement

Pons

Plays a part in sleep, dreaming, left-right body coordination, and arousal

Medulla

Life sustaining functions (breathing, swallowing, and heart rate)

Computed tomography (CT)

Brain-imaging method using computer controlled X-Rays of the brain

Magnetic resonance imaging (MRI)

Brain-imaging method using radio waves and magnetic fields of the body to produce detail images of the brain

Electroencephalograph (EEG)

Machine designed to record the brain wave patterns produced by electrical activity of the surface of the brain

Positron emission tomography (PET)

Brain-imaging method in which a radioactive sugar is injected into the subject and a computer compiles a color coded image of the activity of the brain with lighter color indicating more activity

Functional MRI (fMRI)

functional MRI measures brain activity by detecting changes associated with blood flow
