Despite the plausible assumption that the effects of hallucinogens predominantly arise in the central nervous system, most studies of these drugs in intact subjects have been conducted following systemic administration. The objective of the present investigation was to characterize the stimulus effects of (-)2,5-dimethoxy-4-methylamphetamine ((-)-DOM) following intracerebroventricular...

Previous reports from our laboratory have provided evidence that acute, i.e., concurrent, treatment with selective serotonin reuptake inhibitors (SSRIs) augments the stimulus effects of indoleamine and phenethylamine hallucinogens in the rat. In the present investigation, the acute effects of fluoxetine and citalopram on stimulus control induced by (-)-2,5-dimethoxy-4-methylamphetamine (DOM)...

The role of 5-HT2A-mediated stimulation of phosphoinositide hydrolysis in the discriminative effects of hallucinogens was investigated in PC12 cells stably expressing the rat 5-HT2A receptor (PC12-5-HT2A cells). The hallucinogenic compounds, D-lysergic acid diethylamide (LSD), (-)2,5-dimethoxy-4-methylamphetamine (DOM), psilocybin, N,N-dimethyltryptamine (DMT), 5-methoxy-N,N-dimethyltryptamine...

The present investigation examined the interaction between 2,5-dimethoxy-4-methylamphetamine [DOM] and non-competitive NMDA antagonists in rats trained with DOM [0.6 mg/kg; 75 min pretreatment time] as a discriminative stimulus. Pretreatment with phencyclidine [PCP] at a dose of 3 mg/kg shifted the DOM dose-response relationship to the left. When a fixed dose of DOM [0.1 mg/kg] which by itself...
