Network control energy reductions under DMT relate to serotonin receptors, signal diversity, and subjective experience.

Communications Biology April 18, 2025 S Parker Singleton, Christopher Timmermann, Andrea I. Luppi et al. 17 citations

Psychedelics offer a profound window into the human brain through their robust effects on perception, subjective experience, and brain activity patterns. The serotonergic psychedelic N,N-dimethyltryptamine (DMT) induces a profoundly immersive altered state of consciousness lasting under 20 min, allowing the entire experience to be captured during a single functional magnetic resonance imaging...

Visual Hallucinations in Serotonergic Psychedelics and Lewy Body Diseases

Schizophrenia Bulletin April 17, 2025 Nathan H. Heller, Frederick S. Barrett, Tobias Buchborn et al. 3 citations

Abstract Background and Hypothesis Visual hallucinations (VH) are a core symptom of both Lewy body diseases (LBDs; eg, Parkinson’s disease and dementia with Lewy bodies) and serotonergic psychedelics (SPs; eg, psilocybin and mescaline). While these conditions differ in etiology, overlapping phenomenology, and neural mechanisms suggest shared pathways. This review explores similarities and...

Psilocybin and ketamine affect novel neuropeptides gene expression in the rat hypothalamus

Journal of Psychopharmacology April 17, 2025 Artur Pałasz, Marta Pukowiec, Katarzyna Bogus et al.

Objective: Psychedelics are able to trigger highly intense and profound alterations in self-consciousness, perception, affective, and cognitive processes. Indeed, recent studies show that ketamine and psilocybin could be used as fast-acting antidepressants. However, the molecular and neurochemical mechanisms of these psychedelics and their actions at the level of diverse brain structures...

Dextromethorphan-induced serotonin syndrome leading to rhabdomyolysis and dialysis-requiring acute kidney injury: a case report and review

Renal Replacement Therapy April 15, 2025 Kazuhiro Okamoto, Nobuhiro Hashimoto, Kaiya Ishizeki et al.

Dextromethorphan (DXM) misuse, particularly among young individuals, has risen owing to its euphoric and hallucinogenic effects. High-dose DXM ingestion can trigger serotonin syndrome, a condition characterized by psychiatric, neuromuscular, and autonomic symptoms. In severe cases, serotonin syndrome may result in rhabdomyolysis and acute kidney injury (AKI). However, reports of severe...

Psilocin alleviates acute itch in mice: possible involvement of 5-HT2A receptors and kynurenine pathway.

Naunyn-Schmiedeberg's Archives of Pharmacology April 15, 2025 Arya Afrooghe, Elham Ahmadi, Ali Lesani et al.

We aimed to investigate whether psilocin, the bioactive metabolite of the well-known psychedelic, psilocybin, may have antipruritic effects in mice by interfering with the kynurenine pathway and interacting with 5-HT2A receptors. Eight mice were randomly assigned to each of the study groups receiving either normal saline, compound 48/80, psilocin (0.3, 1, and 3 mg/kg), or psilocin (1 mg/kg) +...
