Babinski, Joseph-Franois-Felix (1857-1932), French neurologist. One of the leading neurologists of his time, Babinski published more than 200 papers, making many important contributions to clinical neurology. In 1896 he made his most famous contribution, his original description of the plantar reflex. He is also known for his critical analysis of cerebellar physiology and symptomatology. He introduced the concept of asynergia and described adiadokokinesis, the inability to perform rapid alternating movements.
