passages.text: Levodopa-induced dyskinesia of the limbs in thirteen cases of Parkinsonism, which was choreic, ballistic or dystonic in type, was alleviated almost completely by stereotaxic surgery using a microelectrode technique for the ventralis oralis anterior and posterior nuclei of the thalamus, but much less by the ventralis intermedius nucleus. Control of levodopa-induced dyskinesias by thalamic lesions in the course of routine treatment of Parkinsonism is discussed.
