An electroencephalogram (EEG) tests your brain function. Healthcare providers order EEGs to diagnose conditions that affect your brain. Providers may use the term EEG for the test itself and what it shows. In an EEG, electrodes placed on your scalp track your brain activity. The electrodes send information to a machine that records brain activity.
