English: First published Electroencephalogram of a human.

This image is one of the first EEGs, appearing in Berger's First Report. It is a portion of fig. 13 from Berger's first publication on EEG:

• Berger H. Über das Elektrenkephalogramm des Menschen. Archives für Psychiatrie . 1929; 87:527-70.

This was later translated into English and republished:

• Berger H. On the Electroencephalogram of Man. Electroencephalogr Clin Neurophysiol . 1969;Suppl 28:37-73. PMID 4188918

It appears on page 58 of the translated version. The top trace is the EEG recorded from a young boy, the bottom trace is a 10 Hz frequency reference.
