What is an EEG?


An EEG records the electrical activity of the brain. Highly-sensitive monitoring equipment records the activity through electrodes that are placed on the patient’s scalp.


Through this painless test, physicians are able to diagnose a variety of neurological problems, from common headaches and dizziness to seizure disorders, strokes and degenerative brain disease.
