The aim of this survey is to present an overview of research into psychopharmacology as regards the effects of different psychoactive drugs and neuroleptics (NL) on language in normal subjects and schizophrenic patients. Eighteen studies that have investigated the effects of different drugs (alcohol, amphetamines, secobarbital, L-dopa, psilocybin, ketamine, fenfluramine) and neuroleptics...

Abstract The following questions regarding the detection of psychoactive drugs in mushrooms are addressed: At what stage of the mushroom development can the psychoactive drugs psilocyn and psilocybin be identified, and what effect does light have on the growth of these mushrooms. To answer these questions, Psilocybe cyanescens Wakefield mushrooms were grown from their spores in a controlled...

The neurotropic effect of Psilocybe cubensis (Earle) Sing, dried biomass and fruiting bodies containing the indole hallucinogens psilocybin and psilocine on spike activity of pyramidal neurons from the rat hippocampal CAl region slices has been studied. Extracellularly responses of 50 neurons were recorded, 34 during the application of biomass extract (BME) and 16 during the application of...

This study investigated possible interactions between alcohol and hallucinogens in 22 lysergic acid diethylamide (LSD) and/or psilocybin users through retrospective structured interviews. Of those who had used LSD with alcohol, 86;7 per cent reported a complete blockade of subjective alcohol effects, while the remaining cases reported a diminished response. In addition, 60 per cent of...

ABSTRACT Language barriers have largely prevented American scholars from learning about European studies concerning drugs and creativity. An art historian reports on several Swiss, English, French and German studies conducted from the 1940s to the 1970s, offering new data in a research area that has been banned since drugs like mescalin, psilocybin, and LSD became illegal. Different views of...

Lysergic Acid Diethylamide (LSD) is a hallucinogenic drug that received considerable attention in the 1960's and early 1970's. It produced a wide variety of psychological phenomena, including a variety of perceptual disturbances which would manifest among some users long after the drug had left the system. These phenomena were commonly referred to as "flashbacks" and may have been largely...

Amphetamines, tryptamines, phencyclidines, tetrahydrocannabinol and substances of the ecstasy group are characterized as stimulants, hallucinogens and entactogens. The various effects of each group and their mode of action in different transmitter systems are described. 28 new compounds of the amphetamine and tryptamine series has been calculated, which exceed the hallucinogenic effects of...

Human experimental research with hallucinogenic drugs is potentially able to identify linking variables between the psycho(patho)logical conditions and neurobiological alterations involved in both pharmacologically induced and naturally occurring acute psychotic states. A number of methodological aspects should be considered when planning modern experimental studies with hallucinogenic drugs....

Recent research into the pharmacological mechanism of hallucinogens (LSD, psilocybin) and dissociative anesthetics (PCP, ketamine) suggest that multiple neurotransmitter systems are involved in drug-induced and possibly also in naturally occurring psychoses. Specifically, animal models suggest that a dysbalance between serotonin, glutamate, and dopamine in the limbic cortico-striato-thalamic...
