Rotation and postural deviation elicited by microinjections of dopamine into medial and lateral regions of dorsal striatum.

Unilateral microinjections of DA (25 micrograms/0.25 microliter) into several medial to lateral regions of the dorsal striatum of female rats produced both contralateral postural deviation and rotation. However, injections of DA into the medial striatum were more effective in producing rotation than postural deviation, whereas the opposite was the case for lateral striatal injections.
