In 1924, Hans Berger was the first person on record to record waves made by the human brain., for which he invented the electroencephalogram, or EEG machine. He also discovered the alpha wave rhythm known as "Berger's wave". He named the band "alpha" because its flagrance made it the first electrical signal he encountered during his initial experiments.
