Abstract
Both atropine sulfate and atropine methyl nitrate (2 mg/kg) were found to suppress VI responding for food reinforcement, while neither had a significant effect on responding for water reinforcement. It was suggested that suppression of thirst-related behavior by anticholinergic substances is a dose-related function of both the central and the peripheral consequences of cholinergic attenuation.
