[The basal ganglia. A clinical and physiopathological approach (author's transl)].

Clinical, anatomical and physiological observations reveal four principal syndromes in the pathology of the basal ganglia: a nigral or putamino-nigral syndrome, a caudate nucleus syndrome, a pallidal syndrome and a luysian syndrome. It seems necessary to make a distinction between those lesions of the neostriatum which are predominately of the putamen.
