Electroencephalography1 ElectroencephalographyAn EEG recording net (Electrical Geodesics,Inc.[1] ) being used on a participant in a brainwave spike and wave discharges monitoredwith (EEG) is the recording of electrical activityalong the scalp produced by the firing of neurons within the brain.[2] Inclinical contexts, EEG refers to the recording of the brain'sspontaneous electrical activity over a short period of time, usually20 40 minutes, as recorded from multiple electrodes placed on thescalp. In neurology, the main diagnostic application of EEG is in thecase of epilepsy, as epileptic activity can create clear abnormalities ona standard EEG study.[3] A secondary clinical use of EEG is in thediagnosis of coma, encephalopathies, and brain death.
