title: Central cholinergic-dopaminergic interaction in carbaryl-induced tremor.
abstract: Acute administration of the anticholinesterase agent carbaryl to rats produced a dose-dependent increase of tremors. The carbaryl-induced tremor was significantly reduced by prior treatment of the rats with either atropine or L-DOPA and was exacerbated by haloperidol. These results suggest the possible involvement of a central cholinergic-dopaminergic interaction in the carbaryl-induced tremor.
