Human psychopharmacology of N,N-dimethyltryptamine
Behavioural Brain Research, 1995We generated dose-response data for the endogenous and ultra-short-acting hallucinogen, N,N-dimethyltryptamine (DMT), in a cohort of experienced hallucinogen users, measuring multiple biological and psychological outcome measures. Subjective responses were quantified with a new rating scale, the HRS, which provided better resolution of dose effects ...

[Elimination of N,N-dimethyltryptamine by urine].
Acta psiquiatrica y psicologica de America latina, 1994N,N-dimethiltryptamine (DMT) in urine has been quantified on an 83-psychiatric patient sample. Sample covered patients who had sometimes been administered neuroleptic drugs as well as patients with some particular symptomatology associated to psychotic disorders such as hallucinations, delusions, perception disorders, etc. 43.3% (36 cases) evidenced an

Rats were tested for shock elicited fighting under various doses of N,N-dimethyltryptamine (0.12, 0.25, 0.50, 1.0, 4.0, 8.0 mg/kg) and 5-methoxy-N,N-dimethyltryptamine (0.06, 0.12, 0.5, 2.0 mg/kg). Both drugs produced an inhibition of fighting at higher doses but no significant effects at lower doses.

Increased synthesis of striatal dopamine by N,N-dimethyltryptamine
Life Sciences, 1977Abstract The effect of acute doses of N,N-dimethyltryptamine (DMT) on the synthesis or degradation rates of rat diencephalon norepinephrine and striatal dopamine was estimated by administering 150 μCi L-tyrosine-3,5- 3 H at various times before sacrifice. In all cases DMT, 20 mg/kg, was injected one-half hour before sacrifice.

Relative potency of amphetamine derivatives and N,N-dimethyltryptamines
Psychopharmacologia, 1971The relative potency of amphetamine derivatives and N,N-dimethyltryptamine (DMT) derivatives was evaluated in rats trained to swim through an underwater tube in order to escape at the other and of the tank. All of the compounds tested significantly increased the starting latency.

Neuroscience & Biobehavioral Reviews, 1982
The present studies examined the role of the spinal cord and the brain in mediating the effects of the hallucinogens N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeODMT) on the acoustic startle response in the rat. Systemic administration of these agents, which distributes to both the brain and spinal cord, produced opposite ...

Endogenous Biosynthesis and Neural Correlates of N,N-dimethyltryptamine
2023N,N-dimethyltryptamine (DMT) belongs to a class of drugs known as serotonergic psychedelics, which produce profound shifts in consciousness by dramatically altering perception and causing hallucinatory phenomena. In humans, DMT has a rapid onset and the effects, which include feelings of dissociation from external reality, entering into an ...
