EEG Electro Encephelogram
EEG) is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp. It measures voltage fluctuations resulting from ionic current within the neurons of the brain. In clinical contexts, it refers to the recording of the brain's spontaneous electrical activity over a period of time, as recorded from multiple electrodes placed on the scalp.
