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.During an EEG, a technician places small metal disks (electrodes) on your scalp. The electrodes attach to a machine that monitors the electrical signals that your brain cells (neurons) make to communicate with each other. Monitoring that communication shows how well the different areas of your brain are working.
