\shȧr-kō\, Jean–Martin (1825–1893),
French neurologist. One of the fathers of modern neurology, Charcot created the greatest neurological clinic of his time. An eminent clinician and pathologist as well as a neurologist, he practiced the method which correlates the moribund patient's symptoms with the lesions discovered during the autopsy. He was the first to describe the disintegration of ligaments and joint surfaces, the condition now known as Charcot's joint or Charcot's disease, caused by tabes dorsalis. He did pioneering work on the determination of the brain centers responsible for specific nervous functions. He demonstrated the clear relationship between psychology and physiology, and his work on hysteria and hypnosis stimulated Sigmund Freud, one of his students, to pursue the psychological origins of neurosis.
