Although spontaneous electrical discharges in the brains of animals were reported as early as 1875, the first recordings from humans were attributed to Hans Berger in 1929. Over the next decade he wrote a remarkable series of papers confirming previous animal studies and showing that the electrical activity was derived from neuronal tissue, that it responded to sensory stimulation, and that abnormal discharges occurred during epileptic seizures (Berger, 1929; Berger, 1938). He used the term electroencephalogram (EEG) to refer to his recordings of this electrical activity.
