Background: Immediate early genes (IEGs) are rapidly activated and initiate diverse cellular processes including neuroplasticity. We report the effect of psilocybin (PSIL), PSIL-containing psychedelic mushroom extract (PME) and 5-hydroxytryptophan (5-HTP) on expression of the IEGs, cfos, egr1, and egr2 in mouse somatosensory cortex (SSC). Methods: In our ini...
Psilocybin, an innate compound produced by mushrooms belonging to the Psilocybe genus, is primarily known for its agonistic effects on the serotonin 5-HT2A receptor. This receptor’s functioning is involved in many neurological processes. In the context of this research, our primary aim was to comprehensively investigate the influence of psilocybin as a serot...
To investigate the relationship between psychedelic microdosing and its effects on mental health, aiming to understand if microdosing can improve mental well-being. PubMed and Scopus were searched on December 25, 2022, using search terms related to psychedelics, microdosing, and mental health. The inclusion criteria focused on studies published between Janua...
Introduction: In psychedelic therapy, mystical as well as challenging experience may influence therapeutic outcome. However, predictors of such experience have not been sufficiently established. Determining predictors of their intensity is, therefore, potentially beneficial in targeting psilocybin therapy for depression. Methods: In a post hoc data analysis ...
To provide insights into neurophenomenological richness after psilocybin intake, we investigated the link between dynamical brain patterns and the ensuing phenomenological pattern after psilocybin intake. Healthy participants received either psilocybin (n=22) or placebo (n=27) while in ultra-high field 7T MRI scanning. Changes in the phenomenological pattern...
Respondents with experience in the use of psychedelics (psilocybin, LSD, ketamine, MDMA, etc.) participated in the study. Based on the subjective assessment of the level of awareness in the topic of psychedelics, it was found that 49% of respondents have a high level, 47% have an average level, and 4% have a low level of awareness in the topic. Most of the s...
BACKGROUND: Evidence suggests that serotonergic psychedelics (e.g. psilocybin), have rapid-acting and long-lasting antidepressant effects after a single dose. However, the mechanism underlying these effects remain unclear. One proposed mechanism is that these drugs promote neuroplasticity. However, this has not been conclusively demonstrated in humans. AIMS:...
Although early therapeutic research on psychedelics dates back to the 1940s, this field of investigation was met with many cultural and legal challenges in the 1970s. Over the past two decades, clinical trials using psychedelics have resumed. Therefore, the goal of this study was to (1) better characterize the recent uptrend in psychedelics in clinical trial...
The purpose of this study is to investigate the prophylactic effects of psilocybin in chronic cluster headache. Subjects will receive a low dose of psilocybin during 3 sessions spaced by one week. Subjects will maintain a headache diary prior to, during, and after the administrations in order to document headache frequency, intensity and duration. Subjects w...
The mystical experience is a potential psychological mechanism to influence outcome in psychedelic therapy. It includes features such as oceanic boundlessness, ego dissolution, and universal interconnectedness, which have been closely linked to both symptom reduction and improved quality of life. In this review, 12 studies of psychedelic therapy utilizing ps...
Several measures have been designed to assess subjective experiences induced by psychedelic substances or other mind-altering drugs as well as non-pharmacological methods. Recently, two self-report questionnaires have been introduced to measure acute adverse effects following psilocybin ingestion and the phenomenon of ego-dissolution associated with the use ...
Despite many different kinds of substances available for depression treatment, depression itself still appears to be a clinical challenge. Recently, formerly illicit substances came to scientists' attention, including lysergic acid diethylamide (LSD), psilocybin and dimethyltryptamine (DMT). Some studies suggest that these substances might be effective in de...
Verbal reports of drug effects are often used in behavioral pharmacology. Two reports related to reinforcement are drug use (Harford, 1978; Liu et al., 2018) frequency and drug preference. Anecdotally, some individuals may specify a favorite/preferred drug (e.g., psilocybin) despite using another drug more frequently (e.g., tobacco). Research comparing these...

Serotonergic hallucinogens such as lysergic acid diethylamide (LSD) induce head twitches in rodents via 5-HT receptor activation. The goal of the present investigation was to determine whether a correlation exists between the potency of hallucinogens in the mouse head-twitch response (HTR) paradigm and their reported potencies in other species, specifically ...
The fully automated system of single drop microextraction coupled with capillary electrophoresis (SDME-CE) was developed for in-line preconcentration and determination of muscimol (MUS) and psilocin (PSC) from urine samples. Those two analytes are characteristic active metabolites of Amanita and Psilocybe mushrooms, evoking visual and auditory hallucinations...
ObjectiveThe relationship between ketamine's hallucinogenic- and dissociative-type effects and antidepressant mechanism of action is poorly understood. This paper reviewed the correlation between subjective effects defined by various psychometric scales and observed clinical outcomes in the treatment of patients with Major Depressive Disorder (MDD).MethodsBa...
Neuroimaging studies of the psychedelic state offer a unique window onto the neural basis of conscious perception and selfhood. Despite well understood pharmacological mechanisms of action, the large-scale changes in neural dynamics induced by psychedelic compounds remain poorly understood. Using source-localised, steady-state MEG recordings, we describe cha...
Some cases consuming Magic mushroom resulting in death and behave strangelinto concerns. Literacy or knowledge of the dangers of this toxic fungus needs to be socialized so that communities especiallyteenagersdid not attempt to try to thrill to get satisfaction because of the nature of the hallucinations caused due by consuming Magic Mushroom. Magic mushroom...
