Hans Berger (1873–1941), a German neuro-psychiatrist, was the first to publish the human electroencephalogram, the recording of the electric activity of the human brain. The method kindled wide public interest for its alleged potential to read foreign minds. After its scientific soundness was confirmed, the method was quickly introduced in research for investigating the neuronal activity within the brain. In addition, it still is an important clinical tool, for example, for diagnosing epilepsy or other neurological conditions.
