Hans Berger (1873–1941): the German psychiatrist who recorded the first electrical brain signal in humans 100 years ago

Abstract

In 1924, at the University Hospital in Jena, Hans Berger first recorded human brain electrical signals, revolutionizing clinical neurophysiology and neurotechnology. He developed the electroencephalogram (EEG) and identified alpha waves in the human scalp. Although initially met with skepticism, his work was later recognized as fundamental. Berger’s perseverance and conviction in his research serve as an inspiring example of dedication for students and scientists in neuroscience.
