Berger and the Breakthrough: A Centennial Celebration of the Human Electroencephalogram

A century ago, it was a challenge for neuroscientists to decipher the mysteries of human brain functioning until German psychiatrist Hans Berger discovered what is now one of the most well-known electrophysiological recording techniques to examine brain function, EEG. He is rightly regarded as the Father of The Electroencephalogram (EEG), since he performed the first human electroencephalogram in 1924. Berger attempted to investigate the connection between psychology and physiology and to solve the "psychic energy" enigma. Despite turbulence in his professional life and slow progress in his research, he persevered and succeeded in giving humankind an indispensable technique that is now widely used in clinical and research practice. His publications on EEG provide valuable insight into our current understanding of several of the brain's responses to physiological and pathological phenomena. In July 2024, it will be 100 years since Berger recorded the first human EEG, and that calls for a celebration among EEG researchers, neuroscientists, psychiatrists, and neurologists. This article presents a brief account of his journey and commemorates Hans Berger's contributions to the field of neurodiagnostics.
