Although cocaine-induced conditioned taste aversions (CTA) are well documented, little is known about the basis for cocaine's aversive effects. To address the role of serotonin (5-HT) in cocaine-induced aversions, the present experiments used the cross-drug preexposure design in which the effects of exposure to fluoxetine, a selective 5-HT reuptake(More)
(1R)-8-chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine (lorcaserin) is approved by the United States Food and Drug Administration for treating obesity, and its therapeutic effects are thought to result from agonist activity at serotonin (5-HT)2C receptors. Lorcaserin has affinity for other 5-HT receptor subtypes, although its activity at those subtypes(More)
Eating high fat chow accelerates the development of sensitization to cocaine-induced locomotion in female rats. It is not known whether consumption of sucrose or saccharin also increases sensitivity to the behavioral effects of cocaine or whether continuous (or intermittent) access to these feeding conditions is necessary to change sensitivity. Adolescent(More)
Genetic and early environmental factors interact to influence ethanol's motivational effects. To explore these issues, a reciprocal cross-fostering paradigm was applied to Fischer and Lewis rats. The adult female offspring received vehicle or the kappa opioid antagonist nor-BNI (1 mg/kg) followed by assessments of conditioned taste aversion (CTA), blood(More)
Although cocaine readily induces taste aversions, little is known about the mechanisms underlying this effect. It has been suggested that its inhibitory effects at one of the monoamine transporters may be mediating this suppression. Using the cross-drug preexposure preparation, the present series of studies examined a possible role of dopamine (DA) in this(More)
Although the mechanism underlying the rewarding effects of cocaine has been well characterized, little is known about the mechanism underlying its aversive effects. Several reports have indicated a possible role of dopamine (DA) in the aversive effects; however, several procedural issues limit any conclusions regarding its specific role. In order to(More)
Although cocaine readily induces taste aversions, little is known about the mechanisms underlying this effect. The present series of studies used the cross-drug preexposure design to determine if desipramine (DMI), a selective NE transporter (NET) inhibitor, and cocaine (a nonselective monoamine transport inhibitor) induce aversions by a common mechanism,(More)
Diet can impact sensitivity of rats to some of the behavioral effects of drugs acting on dopamine systems. The current study tested whether continuous access to sucrose is necessary to increase yawning induced by the dopamine receptor agonist quinpirole, or if intermittent access is sufficient. These studies also tested whether sensitivity to(More)
Feeding conditions can impact sensitivity to drugs acting on dopamine receptors; less is known about the impact of feeding conditions on the effects of drugs acting on serotonin (5-HT) receptors. This study examined the effects of feeding conditions on sensitivity to the direct-acting 5-HT(2A/2C) receptor agonist(More)
Eating high fat chow increases the sensitivity of male rats to some behavioral effects of the direct-acting dopamine receptor agonist quinpirole; it is not known whether sensitivity to quinpirole is similarly enhanced in female rats eating high fat chow. Female Sprague-Dawley rats had free access to standard chow (5.7% fat) or either free or restricted(More)
