What is an electroencephalogram (eeg)?

EEG: An EEG is a test that records the various brain waves emitted from the brain. The test is done by placing tiny electrodes all around the head and scalp, and recording the electrical activity emitted by the brain and recorded by tracing the waves onto recording paper.

Tests brain activity: A noninvasive, painless exam where electrodes are placed on scalp and electrical activity is recorded via computer. Patient usually sits in a chair, or lays on a stretcher. Indications include seizures and other causes of brain dysfunction. May be used to both diagnose and monitor a seizure disorder.
