Effects of atropine on conditioned taste aversion
Abstract:
Atropine sulfate, which has a deleterious effect on various learning tasks, was found to have a similar effect on the acquisition of conditioned taste aversion. Thus, intraperitoneal injection of atropine sulfate shortly before tasting was found to interfere with conditioning of the aversion, but injection of atropine after tasting did not. The interference effect was also obtained with intraventricular administration of atropine sulfate, but not with intraperitoneal injection of the peripherally-acting atropine methylnitrate. These results show that central rather than peripheral mechanisms are involved in this effect, and suggest that conditioned taste aversion, like other kinds of learning, involves cholinergic mediation.
