Glutamate signaling in the nucleus accumbens influences reinstatement of previously extinguished cocaine-seeking behavior in rats. Whether or not region specific glutamate signaling in the nucleus accumbens contributes to reinstatement of cocaine-seeking behavior is not known. We investigated whether directly stimulating ionotropic glutamate receptors(More)
Fischer 344 (F344) and Lewis (LEW) rats differ in a number of self-administration behaviors. Whether or not these strains differ in methamphetamine-primed reinstatement of extinguished responding is unknown. F344 and LEW rats were trained to self-administer intravenous (i.v.) methamphetamine (0.06 mg/kg) during daily 2-h limited access sessions for 14 days.(More)
RATIONALE Fischer 344 (F344) and Lewis (LEW) rats differ in cocaine self-administration behaviors. Whether or not these inbred strains of rats differ in pharmacological reinstatement of cocaine-seeking behavior is unknown. OBJECTIVES The purpose of the present study was to determine if inbred strains of rats demonstrate differences in(More)
Fischer 344 (F344) and Lewis (LEW) rats differ in methamphetamine self-administration (SA) and methamphetamine-induced reinstatement of previously extinguished behavior. We sought to determine whether genetic background also influences methamphetamine reinforcement efficacy, conditioned reinstatement, and methamphetamine-primed reinstatement of responding(More)
Although some central effects of citral have been reported, cognitive effects on spatial memory have not been investigated. The evidence showed that citral can regulate the synthesis of retinoic acid (RA), which exerts a vital function in the development and maintenance of spatial memory. In this study, we applied Morris water maze to test the effect of(More)
