Pharmacological challenges with hallucinogens are used as models for psychosis in experimental research. The state induced by glutamate antagonists such as phencyclidine (PCP) is often considered as a more appropriate model of psychosis than the state induced by serotonergic hallucinogens such as lysergic acid (LSD), psilocybin and dimethyltryptamine (DMT). However, so far, this question has...

The objectives of the present study were to investigate the capacity of several hallucinogenic compounds...
