The effect of cholinergic antagonists on a central response to nicotine

Abstract
Mecamylamine and hexamethonium antagonize the prostration response of rats to centrally-administered nicotine; decamethonium and d-tubocurarine are less effective. Physostigmine does not elicit the response. Nicotine's central cholinergic effect thus may contribute to but does not fully account for its action.
