[Babinski's legacy].

Joseph Babinski may be considered as a founder of modern neurology. Based upon a strict neurological examination, he was able to clarify a clinical distinction between hysterical and organic symptomatology. Besides his observation on the Sign, which made him world famous, his description of new concepts in cerebellar signs, his studies on reflexes constituted important landmarks in clinical neurology. But he was also a therapist, moving from palliative treatment to give a great impulse in the development of French Neurosurgery.
