Abstract
The action of methylpentynol and methylpentynol carbamate on the perfused superior cervical ganglion of the cat was analysed. Both drugs, in doses of 1 to 5 mg., depressed the output of acetylcholine. If the acetylcholine output was reduced by more than about 50%, transmission failed. Both drugs also reduced the response of the ganglion to injected acetylcholine. The carbamate, but not methylpentynol itself, had a transient stimulant action on the ganglion, unaccompanied by acetylcholine release.
