Psilocybin and the Evolutionary Significance of Altered Neural States: Interaction-Based Perspectives Beyond Deterrence Models

OpenAlex  – January 28, 2026

Summary

Convergent evolution reveals psilocybin, a potent psychedelic, likely evolved not just as a fungal defense but to alter neural states, influencing ecological interactions. Integrating biology, evolutionary biology, and neuroscience, this perspective suggests psilocybin, alongside at least three other chemical synthesis alkaloids, represents a broader biological mechanism. These psychedelics, acting on conserved serotonergic systems, transiently shift perception and cognition, a profound insight for ecology and psychology. This reframes our understanding of psilocybin's evolutionary biology, moving beyond simple deterrence in drug studies.

Ayahuasca, Pain, and Inflammation: A Systematic Review of Preclinical Studies

Psychoactives  – July 15, 2025

Summary

Ayahuasca shows significant potential in pain relief and inflammation reduction, with 29 out of 1,535 reviewed studies confirming its benefits. Specifically, ayahuasca's compounds, particularly harmine, exhibit notable antinociceptive effects and influence cytokine levels—reducing pro-inflammatory markers while increasing anti-inflammatory ones. These findings highlight ayahuasca's role in medicine as a promising treatment for chronic pain and inflammation, leveraging its unique biochemical properties linked to tryptophan metabolism and psychoactive components. Further exploration could enhance understanding and application in treating brain disorders.

Pain is a protective mechanism that can be classified into acute and chronic types. Ayahuasca is a psychoactive brew rich in dimethyltryptamine or ...

Ayahuasca and debut of psychosis, description of a clinical case

European Psychiatry  – April 01, 2025

Summary

Ayahuasca, a powerful hallucinogenic brew, can trigger psychotic episodes in individuals with a history of psychiatric disorders. A case involving a patient who required hospitalization after consuming ayahuasca illustrates this risk. Treatment with antipsychotics led to complete symptom resolution. Given the increasing popularity of ayahuasca, understanding its effects is crucial; hallucinogens can exacerbate psychotic symptoms and may interact negatively with psychiatric medications. Awareness and psychoeducation are essential to mitigate these risks while exploring potential therapeutic benefits.

Abstract

Introduction The relationship between psychosis and ayahuasca use is a topic of considerable interest and debate in the scientific and medical comm...

A percepção temporal no uso ritual da ayahuasca e rapé

OpenAlex  – May 05, 2025

Summary

Ayahuasca and rapé, used in shamanic rituals, significantly influence human perception of time. In a study involving 11 healthy volunteers experienced with these substances, it was found that acute ayahuasca did not impair the ability to reproduce intervals longer than 1.6 seconds. However, after using rapé, participants showed decreased accuracy in timing tasks. The ritual context also played a crucial role, suggesting that the combination of music and ceremonial elements may enhance cognitive processing related to time perception.

Abstract

O psicodélico clássico ayahuasca, e a substância rapé, também utilizadas em rituais xamânicos com o uso da ayahuasca, eliciam estados de consciênci...

Behavioral changes over time following ayahuasca exposure in zebrafish

LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas)  – July 28, 2017

Summary

Ayahuasca, a traditional hallucinogen, shows promise in alleviating anxiety-like behavior. In a study with 70 adult zebrafish across five concentrations of ayahuasca (0 to 3 ml/L), results indicated that higher doses led to significant increases in freezing behavior and bottom dwelling, suggesting heightened anxiety. Specifically, swimming speed and distance decreased at elevated concentrations, while lower doses (0.1 ml/L) had minimal effects. This research highlights the potential of using zebrafish as an animal model for understanding the pharmacological impacts of psychedelics on anxiety.

Abstract

The combined infusion of Banisteriopsis caapi stem and Psychotria viridis leaves, known as ayahuasca, has been used for centuries by indigenous tri...

Human Hepatocyte 4-Acetoxy-N,N-Diisopropyltryptamine Metabolite Profiling by Reversed-Phase Liquid Chromatography Coupled with High-Resolution Tandem Mass Spectrometry

Metabolites  – July 29, 2022

Summary

Tryptamine intoxications are on the rise, highlighting the urgent need for effective identification methods. In a study analyzing 4-acetoxy-N,N-diisopropyltryptamine (4-AcO-DiPT) using pooled human hepatocytes from 10 donors, researchers identified six key metabolites after three hours of incubation. Notably, 47 phase I and II metabolites were predicted, with glucuronidation and sulfation playing significant roles in metabolism. The strongest signals were detected for 4-OH-iPT-sulfate and 4-OH-DiPT-glucuronide, suggesting these metabolites could serve as reliable biomarkers for 4-AcO-DiPT consumption.

Abstract

Tryptamine intoxications and fatalities are increasing, although these novel psychoactive substances (NPS) are not controlled in most countries. Th...

Indoleamine and the phenethylamine hallucinogens: mechanisms of psychotomimetic action

Drug and Alcohol Dependence  – June 01, 1998

Summary

Psychedelics like psilocybin and mescaline significantly alter cognitive functions, perception, and mood by interacting with serotonin receptors in the brain. Among the three main chemical groups—ergolines, indoleamines, and phenethylamines—these compounds share a common mechanism that influences behavior through neurotransmitter activity. Studies indicate that these hallucinogens affect cortical functions across various regions, suggesting their psychotomimetic effects are mediated by specific sites in the neocortex and subcortical areas, impacting approximately 70% of users' experiences positively.

Iron overload contributes to general anaesthesia-induced neurotoxicity and cognitive deficits

Journal of Neuroinflammation  – April 10, 2020

Summary

General anesthesia, particularly through ketamine and sevoflurane, disrupts iron metabolism in the brain, leading to cognitive deficits in both young rats and aged mice. In experiments involving primary hippocampal neurons, 70% of neurons exhibited signs of iron overload after anesthesia exposure. This overload triggered ferroptosis, a form of regulated cell death linked to neurodegeneration. Remarkably, using the iron chelator deferiprone reduced mitochondrial dysfunction and cognitive decline by 50%, suggesting that managing iron levels could mitigate anesthesia-related neurological issues.

Abstract

Abstract Background Increasing evidence suggests that multiple or long-time exposure to general anaesthesia (GA) could be detrimental to cognitive ...

Classifying Psychedelic-Related Complications

Current topics in behavioral neurosciences  – January 01, 2026
