[Electroencephalography - from the past to the present - the development during the 100 years after Berger].

Abstract

In 1924 the German psychiatrist Hans Berger made the first electroencephalographical (EEG) recording of cerebral activity in humans. Worldwide, EEG developed into a widely used diagnostic method and was introduced in Sweden in 1937. Today EEG is an essential diagnostic and monitoring standard in epilepsy, sleep disorders, neonatology and intensive care, and provides prognostic information after perinatal asphyxia and cardiac arrest. Like ECG, EEG is an old electrophysiological method that today, and in the future, provides unique diagnostic information.
