An EEG is a non-invasive test that records brain electrical activity. It involves wearing a cap with small metal discs (electrodes) attached with gel on the scalp. Brain neurons communicate through electrical impulses and remain active all the time, even during sleep. This neuronal activity is captured by the electrodes and translated into EEG waveforms.

EEG is one of the main tests used to diagnose epilepsy, and may also have a role in diagnosing other brain disorders.
