Hans Berger has been credited with the invention of the EEG. His first EEG was recorded in July 1924, during neurosurgery on a 17-year-old boy. Following development of non-invasive EEG recording and its use in males and females of different ages he concluded that brainwaves change during mental activities and sleep.1 In 1932, he published the first report of an EEG following a generalized tonic‒clonic seizure.2
