Co-administration of midazolam and psilocybin: Differential effects on subjective quality versus memory of the psychedelic experience

OpenAlex  – June 13, 2024

Summary

The profound psychological benefits of the serotonergic hallucinogen psilocybin may depend on remembering the experience. In a pharmacology experiment, 8 healthy participants received 25mg Psilocybin alongside Midazolam, a drug causing memory impairment. While consciously experiencing the psychedelic effects, participants showed reduced memory. Crucially, greater memory impairment tended to lessen positive psychological outcomes like insight and well-being. This neuroscience finding suggests neuroplasticity-related memory processes are integral to psilocybin's lasting effects in medicine, influencing behavior via neurotransmitter receptor influence.

Abstract

Abstract Aspects of the acute experience induced by the serotonergic psychedelic psilocybin predict symptomatic relief in multiple psychiatric diso...

Associations between classic psychedelics and nicotine dependence in a nationally representative sample

Scientific Reports  – June 22, 2022

Summary

Lifetime psilocybin use is linked to reduced odds of nicotine dependence. A large psychology study of 214,505 adults found psilocybin use was associated with 7-13% lower odds of current nicotine dependence. Mescaline and peyote also showed 9-21% reduced odds of specific nicotine dependence measures. However, LSD use was associated with 17-24% *increased* odds. This logistic regression analysis suggests certain hallucinogen psychedelics might offer new avenues in medicine and psychiatry for addiction and smoking cessation, influencing nicotinic acetylcholine receptors. This field of drug studies explores novel approaches to addiction.

Investigation of neuronal basis underlying antidepressant effect of serotonergic psychedelics

Proceedings for Annual Meeting of The Japanese Pharmacological Society  – January 01, 2022

Summary

Psilocybin's antidepressant pharmacology, a key area in psychedelics and drug studies, is now clearer. Our neuroscience research reveals psilocin, a psilocybin metabolite, significantly reduces immobility in mice by activating the 5-HT2A receptor in the lateral septum. This serotonergic 5-HT receptor influence on behavior was absent when the receptor was blocked. Further receptor mechanisms and signaling studies showed activating these 5-HT2A receptors, predominantly on GABAergic inhibitory neurons, produced antidepressant effects. This chemistry suggests neurotransmitter receptor influence on behavior via these specific inhibitory pathways.
