The Effects of Daytime Psilocybin Administration on Sleep: Implications for Antidepressant Action
Frontiers in Pharmacology – December 03, 2020
Summary
Psilocybin, a psychedelic with antidepressant potential, significantly alters sleep architecture. In a study of 20 healthy volunteers (10 women), psilocybin prolonged rapid eye movement (REM) sleep latency and showed a trend towards decreased overall REM sleep duration. Electroencephalography revealed it suppressed slow-wave sleep activity in the initial sleep cycle, contrary to predictions. Non-rapid eye movement sleep remained unchanged. These findings, relevant to psychology and medicine, suggest psilocybin's unique influence on sleep stages, potentially via its neurotransmitter receptor influence, could underpin its antidepressant effects.

Contribution of serotonin receptor subtypes to hallucinogenic activity of 25I-NBOMe and to its effect on neurotransmission.
Pharmacological reports : PR – December 01, 2020
Summary
Blocking specific serotonin receptors dramatically reduces the hallucinogenic activity of 25I-NBOMe. Administering 5-HT2A and 5-HT2C receptor antagonists (100 nM) markedly attenuated the wet dog shake response in rats given 1 or 3 mg/kg of 25I-NBOMe. These antagonists also inhibited increased neurotransmission of dopamine, serotonin, and glutamate. While a 5-HT1A receptor antagonist did not affect hallucinogenic activity, it decreased dopamine and serotonin release. This reveals the critical role of 5-HT2A and 5-HT2C receptors in 25I-NBOMe's effects.

Psychological Medicine – November 04, 2020
Summary
Psychedelics like psilocybin and ayahuasca, potent hallucinogens, demonstrate substantial mental health benefits. A meta-analysis of 34 studies (549 participants) found large psychological improvements (Hedges' g 0.84-1.08) versus placebo in randomized controlled trials. These effects, potentially linked to neurotransmitter receptor influence on behavior, spanned psychiatry and clinical psychology, with moderation for clinical samples. No post-acute adverse effect was observed, advancing interest in these chemical synthesis and alkaloids for Psychedelics and Drug Studies.

Transcriptional regulation in the rat prefrontal cortex and hippocampus after a single administration of psilocybin
Journal of Psychopharmacology – November 04, 2020
Summary
Psilocybin, a psychedelic compound from "magic mushrooms," rapidly boosts gene expression linked to neuroplasticity, particularly in the prefrontal cortex. In a study with 20 rats, doses of psilocybin (0.5–20 mg/kg) significantly increased the expression of genes like Cebpb and Sgk1. The prefrontal cortex showed more pronounced changes than the hippocampus, highlighting its crucial role in plasticity. Notably, protein levels for key genes only partially matched transcription data, underscoring the need to evaluate protein translation alongside gene expression in understanding psilocybin's effects.
Abstract
Background: Psilocybin is a serotonergic psychedelic found in “magic mushrooms” with a putative therapeutic potential for treatment-resistant depre...

Effects of external stimulation on psychedelic state neurodynamics
OpenAlex – November 02, 2020
Summary
Psychedelics reliably enhance brain entropy, a measure of neural signal diversity, which typically decreases with loss of consciousness. Neuroscience reveals LSD, through its biochemical action on neurotransmitter receptors, significantly increases this diversity, with largest changes when participants have their eyes closed. This finding from Psychedelics and Drug Studies highlights how external stimulus profoundly influences cognitive psychology and subjective experience. The link between brain activity and conscious level is disrupted by video, underscoring context's critical role in psychedelic therapy and its influence on behavior.
Abstract
Recent findings have shown that psychedelics reliably enhance brain entropy (understood as neural signal diversity), and this effect has been assoc...
