Electroencephalography (EEG) is a neuroimaging technique utilized to record the brain's electrical activity from the surface of the scalp. Between the smooth, sinusoidal EEG rhythms of regular brain waves and the clearly pathological abnormalities seen in epilepsy lies a controversial and brief aberration called the sharp wave. A sharp wave, also known as an epileptiform or paroxysmal discharge, is time-limited electrical event that represents several thousands of excitable neurons firing synchronously. While some researchers and clinicians approach sharp waves as important factors of...
