Abstract Background and Aims The hallucinogenic drug psilocybin is being widely tested in humans for the treatment of psychiatric disorders. Psilocybin and other psychedelics are proposed to work through serotonin 2a (5-HT2a) receptors, which are tightly linked to immune function. The purpose of the present study was to assess the effects of a single dose of psilocybin on a panel of cytokines,...

2,5-Dimethoxy-4-methylamphetamine (DOM) was infused into discrete brain regions of rats trained to press a bar for food reinforcement on a fixed ratio-40 (FR-40). Sites were chosen as major areas of the brain 5-hydroxytryptamine (5-HT) system: the dorsal and median raphe nuclei, dorsal hippocampus, lateral habenular nuclei and the prefrontal cortex. Following training in a fixed ratio-40...

Indolealkylamine and phenethylamine hallucinogens disrupted responding maintained under a fixed-ratio 40 (FR-40) schedule of reinforcement. LSD, DMT, mescaline and DOM produced dose-dependent decreases in number of reinforcers and increases in 10-sec periods of non-responding (pause-intervals). The 5HT agonist quipazine, as well as the LSD congener lisuride, altered response patterns in a...

Administration of the indolealkylamine hallucinogen d-lysergic acid diethylamide (LSD), the phenethylamine hallucinogen 2,5-dimethoxy-4-methylamphetamine (DOM) and the putative 5-hydroxytryptamine (5-HT) agonist quipazine all produced a dose-dependent decrease in fixed ratio (FR-40) response rates and a concomitant increase in the number of 10-second pause intervals. Although naloxone (4.0...

The effects on a fixed ratio-40 (FR-40) operant behavior of intracerebroventricular (ICV) administration of the hallucinogens lysergic acid diethylamide (LSD), 2,5-dimethoxy-4-methylamphetamine (DOM), mescaline or the non-hallucinogenic LSD-analogue lisuride were compared with intraperitoneal (IP) administration. Infusion of LSD (8.5 to 34 micrograms) into the left lateral ventricle produced a...

The hypothesis that 5-hydroxytryptamine (5-HT) neurons and/or receptors are involved in the mechanism of action of hallucinogens is supported by the fact that intraventricular administration of the neurotoxin 5,7-dihydroxytryptamine (5,7-DHT) selectively destroys central 5-HT neurons in the brain and potentiates the behavioral effects of lysergic acid diethylamide (LSD),...
