Psychedelic expert: Shrooms will be approved for depression in 10 years

Ask a healthy person who’s tripped on psychedelics what it felt like, and they’ll probably tell you they saw sounds or heard colors: The crash-bang of a dropped box took on an aggressive,dark shape. A bright green light seemed to emit a piercing, high-pitched screech. In actuality, this “cross-wiring” — synaesthesia, as it’s known scientifically — may […]

Psilocybin for treatment-resistant depression

Psilocybin for treatment-resistant depression

Twelve people with moderate to severe treatment-resistant depression who had not responded to at least two courses of antidepressants were recruited (six men and six women, aged 30 to 64). Most of the participants actively volunteered to take part following presentations by the researchers and media coverage. Hallucinogenics such as psilocybin can cause unpleasant reactions, […]

Magic mushrooms’ effects illuminated in brain imaging studies

Magic mushrooms’ effects illuminated in brain imaging studies

The intensity of the effects reported by the participants, including visions of geometric patterns, unusual bodily sensations and altered sense of space and time, correlated with a decrease in oxygenation and blood flow in certain parts of the brain. Professor David Nutt, from the Department of Medicine at Imperial College London, the senior author of both studies, […]

Functional Connectivity Measures After Psilocybin Inform a Novel Hypothesis  of Early Psychosis

Functional Connectivity Measures After Psilocybin Inform a Novel Hypothesis of Early Psychosis

Functional Connectivity Measures After Psilocybin Inform a Novel Hypothesis of Early Psychosis Psilocybin is a classic psychedelic and a candidate drug model of psychosis. This study measured the effects of psilocybin on resting-state network and thalamocortical functional connectivity (FC) using functional magnetic resonance imaging (fMRI). Fifteen healthy volunteers received intravenous infusions of psilocybin and placebo in […]

The effects of psilocybin and MDMA on between-network resting state functional connectivity

The effects of psilocybin and MDMA on between-network resting state functional connectivity

The effects of psilocybin and MDMA on between-network resting state functional connectivity in healthy volunteers Perturbing a system and observing the consequences is a classic scientific strategy for understanding a phenomenon. Psychedelic drugs perturb consciousness in a marked and novel way and thus are powerful tools for studying its mechanisms. In the present analysis, we […]

Cause for a re- think on drug models of psychosis and other  psychiatric disorders

Cause for a re- think on drug models of psychosis and other psychiatric disorders

Psychiatry’s next top model: cause for a re-think on drug models of psychosis and other psychiatric disorders RL Carhart-Harris, S Brugger, DJ Nutt and JM Stone Despite the widespread application of drug modelling in psychiatric research, the relative value of different models has never been formally compared in the same analysis. Here we compared the […]
