An improved rotometer is described which accurately records circling behavior (rotation) in rats with an imbalance of the nigrostriatal pathways. Results of circling induced by apomorphine in rats with unilateral 6-hydroxydopamine lesions of the substantia nigra and circling elicited by electrical stimulation of the nigrostriatal pathway are presented. © 1978.
