Brain Scans

• Electroencephalogram (EEG)

  records brain's electrical activity, measures waves via electrodes -> scalp, identifies seizures/abnormalities
• Magnetoenceplalography (MEG)

  measures magnetic activity from brain's electrical activity; neurons -> electrical impulses -> magnetic fields
• Computed Tomography (CT)

  examines brain structure via x-rays, determines the shape/position of brain structures
• Position Emission Tomography Scan (PET)

  exposes brain region activity & observes its metabolic activity -> brain function
• Magnetic Resonance Imaging (MRI)

  magnetic pulses visually depict the brain, exposing potential damage
• Functional MRI

  measures blood flow/oxygen to examine brain function
