Electrical stimulation of the caudate nucleus on one side induces a contraversive lateral fixation of the neck which is often followed by postural asymmetry and circling in the cat and other species. Caudate-induced HT (Cd-HT) can be regarded as being closely related to a process of the postural control exerted by the basal ganglia. Conversely, lesions in the striatum of the rat produced by both kainic acid and 6-hydroxydopamine resulted in impairment in sensory-motor orientation of the head to contralateral stimuli. Hassler and Dieckmann recorded that eye and head movements in the same direction were induced by stimulation of the pallidum of the cat. The effects of stimulation of the caudate nucleus on eye movements, however, have not been analyzed systematically.
