Electroencephalography

Electroencephalography is the process of recording, by electrodes placed on the scalp, a graphic chart tracing the electrical potentials produced by the brain cells and is commonly abbreviated as EEG.

Hans Berger (born on May 21, 1873 and died on June 1, 1941) is credited to be the first to record electroencephalograms from human subjects and is the discoverer of the rhythmic Alpha waves in the brain.
