Hans Berger

Hans Berger was a German psychiatrist best known for inventing the electroencephalogram (EEG) in the early 20th century. This device measures electrical activity in the brain, allowing scientists and doctors to study brain waves and diagnose conditions like epilepsy and sleep disorders. Berger's work laid the foundation for modern neuroscience, enabling deeper understanding of brain function, mental health, and the impact of various disorders on neural activity. His pioneering research has had a lasting influence on both psychological and neurological fields, opening avenues for treatment and understanding of the human brain.
