Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used in specific applications. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain.
By Reza Shouri, MD. Updated February 09, 2016. An electroencephalogram, or EEG, is one of the available tests used to diagnose epilepsy, and it's used quite commonly when doctors suspect someone has epilepsy. The electroencephalogram, or EEG, measures and records the electrical activity of the neurons in the brain. An EEG can tell your healthcare provider if there is abnormal electrical activity in the brain and, in some cases, the types of seizures you might be experiencing.
