Recreational 3,4-methylenedioxymethamphetamine or 'ecstasy': Current perspective and future research prospects.

Journal of Psychopharmacology August 2017 Andrew C. Parrott, Luke A. Downey, Carl A Roberts et al.

The purpose of this article is to debate current understandings about the psychobiological effects of recreational 3,4-methylenedioxymethamphetamine (MDMA or 'ecstasy'), and recommend theoretically-driven topics for future research. Recent empirical findings, especially those from novel topic areas were reviewed. Potential causes for the high variance often found in group findings were also...

Characterization of the discriminative stimulus effects of 3,4-methylenedioxypyrovalerone in male Sprague-Dawley rats.

Behavioural Pharmacology August 2017 Michael D. Berquist, Lisa E Baker

Recreational use of 3,4-methylenedioxypyrovalerone (MDPV) in the early 2000s prompted numerous scientific investigations of its behavioral and neurochemical effects. The purpose of this study was to further characterize the interoceptive stimulus effects of MDPV using a validated in-vivo drug-detection assay. Male Sprague-Dawley rats were trained to discriminate 0.3 mg/kg MDPV from saline under...

Amphetamine-related drugs neurotoxicity in humans and in experimental animals: Main mechanisms.

Progress in Neurobiology August 2017 Rosario Moratalla, Amit Khairnar, Nicola Simola et al.

Amphetamine-related drugs, such as 3,4-methylenedioxymethamphetamine (MDMA) and methamphetamine (METH), are popular recreational psychostimulants. Several preclinical studies have demonstrated that, besides having the potential for abuse, amphetamine-related drugs may also elicit neurotoxic and neuroinflammatory effects. The neurotoxic potentials of MDMA and METH to dopaminergic and...

Behavioral changes over time following ayahuasca exposure in zebrafish

LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas) July 28, 2017 Robson Savoldi, Daniel Polari, Jaquelinne Pinheiro‐da‐silva et al.

The combined infusion of Banisteriopsis caapi stem and Psychotria viridis leaves, known as ayahuasca, has been used for centuries by indigenous tribes. The infusion is rich in N, N-dimethyltryptamine (DMT) and monoamine oxidase inhibitors, with properties similar to those of serotonin. Despite substantial progress in the development of new drugs to treat anxiety and depression, current...

Qualitative and Quantitative Features of Music Reported to Support Peak Mystical Experiences during Psychedelic Therapy Sessions

Frontiers in Psychology July 25, 2017 Hollis Robbins, David Smooke, Frederick S. Barrett et al. 62 citations

Psilocybin is a classic (serotonergic) hallucinogen ("psychedelic" drug) that may occasion mystical experiences (characterized by a profound feeling of oneness or unity) during acute effects. Such experiences may have therapeutic value. Research and clinical applications of psychedelics usually include music listening during acute drug effects, based on the expectation that music will provide...

Pranayama a Neuro-Physiological Explanation of the Mechanism

Journal of Yoga and Physiotherapy July 13, 2017 V. Casikar

Yoga is an ancient Indian way of life which includes changes in mental attitude, diet and practice of specific techniques (Asanas), breathing practices (Pranayama) and medication to obtain highest level of consciousness. Pranayama or regulated breathing is considered as one of the essential aspects of Yoga. When a person breathes the olfactory nerves situated in the roof of the nose are...

The psychoactive drug 25B-NBOMe recapitulates rhabdomyolysis in zebrafish larvae

Forensic Toxicology July 1, 2017 Genri Kawahara, Hideyuki Maeda, Ruri Kikura-Hanajiri et al. 17 citations

N -Benzyl-substituted 2C class phenethylamines (NBOMes) are psychoactive designer drugs, with strong hallucinogenic and stimulant effects, even at low doses. The designer drug, 2-(4-bromo-2, 5-dimethoxyphenyl)- N -(2-methoxybenzyl) ethanamine (25B-NBOMe) is considered to be one of the most potent agonists of the serotonin-2A (5-HT_2A) receptor. Recently, we reported the first lethal case of...

Por uma abordagem ecológica dos efeitos anti-depressivos da ayahuasca

Ponto Urbe June 30, 2017 Danielli Katherine Pascoal Da Silva 5 citations

A partir de pesquisa de campo em preparos de Vegetal na UDV,notei que os efeitos da Hoasca não são atribuídos exclusivamente à Dimetiltriptamina (DMT) presente na Psychotria Viridis e nas betacarbolinas do Banisteriopsis Caapi, mas à mútua aprendizagem entre inteligências humana e Vegetal. Esta concepção assemelha-se com outras indígenas, nas quais a ayahuasca é vista como um Ser cuja ação...

Effect of Psilocybin on Empathy and Moral Decision-Making

The International Journal of Neuropsychopharmacology June 14, 2017 Thomas Pokorny, Katrin H. Preller, Michael Kometer et al. 202 citations

Background: Impaired empathic abilities lead to severe negative social consequences and influence the development and treatment of several psychiatric disorders. Furthermore, empathy has been shown to play a crucial role in moral and prosocial behavior. Although the serotonin system has been implicated in modulating empathy and moral behavior, the relative contribution of the various serotonin...
