Previous studies have shown that stressors attenuate LiCI-induced conditioned taste aversions (CTA) but not morphine-induced CTA. The current studies examined the effects of footshock on the acquisition and extinction of amphetamine-induced CTA. Experiment 1 demonstrated that exposure to 30 footshocks between saccharin consumption and amphetamine injections did not alter either the acquisition or the extinction of amphetamine-CTA. Experiment 2 demonstrated that exposure to the same shock parameters 2 and 4 days before saccharin-amphetamine pairing increased the magnitude of amphetamine-CTA after one saccharin-amphetamine pairing and delayed the recovery from the CTA. Experiment 2 also demonstrated that footshock increased the initial neophobic response to novel saccharin but did not alter subsequent saccharin consumption among saline-injected animals. These results indicate that stress-induced facilitation of amphetamine CTA are time-dependent and contrast with reports that stressors attenuate LiCI CTA. They also add support to the contention that CTAs induced by self-administered drugs like amphetamine are qualitatively different from CTAs induced by toxic substances like LiCL.

D000661 Amphetamine A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.
