title: Dopamine depletion by 6-hydroxydopamine prevents conditioned taste aversion induced by methylamphetamine but not lithium chloride.
abstract: Specific lesions of the central dopaminergic system produced by intraventricular injections of 6-hydroxydopamine with pargyline and desmethylimipramine pretreatment significantly attenuated conditioned taste aversions to a sweetened-condensed milk solution induced by methylamphetamine. Identically treated rats formed an aversion to the milk solution when lithium chloride was utilized. These results suggest that the methylamphetamine-induced aversion is dependent upon intact dopaminergic neurons.
