Brain electricity writing

Human brainwaves were first measured in 1924 by Hans Berger, at the time an unknown German psychiatrist. He termed these electrical measurements the “electroencephalogram” (EEG), which literally means “brain electricity writing”.
Berger published his brainwave results in 1929 as Über das Elektrenkephalogramm des Menschen (“On the Electroencephalogram of Man”). The English translation did not appear until 1969.
