[Comparative study of rotatory movements elicited by stimulation of the putamen and caudate nucleus in the cat].
Electrical stimulation of the putamen and caudate nucleus elicits the same sequence of rotatory movements and accompanying reactions in alert cats. Some types of rotations, however, are more difficult to trigger from the putamen whereas the side--effects are rather facilitated in general. The neuroleptic drug haloperidol weakens the putamen--induced contralateral turning of the head whereas thresholds of the caudate--induced responses tend to reduce. Different dopaminergic organization of the neostriatal nuclei may be the cause of the variations.
