The effects of psilocybin on time perception in humans: A comparative analysis of subjective and objective measures

Journal of Psychopharmacology 2026 Petr Scholle, Štěpán Wenke, Tereza Nekovářová et al. 1 citation

Background: Although psychedelics have regained attention as potential treatment tools for various mental disorders, little research has examined their impact on temporal perception. Aims: This double-blinded placebo-controlled study aimed to investigate changes in temporal perception under psilocybin, both through performance during the Temporal Bisection Task (TBT) and through subjective...

Sympathetic activation but not dissociation linked to ketamine's sustained antidepressant effect.

Therapeutic Advances in Psychopharmacology 2026 Veronika Andrashko, Tomáš Novák, Miloslav Kopecek et al.

Ketamine is a rapid-acting antidepressant with robust evidence, but unclear predictors of therapeutic response. Based on previous knowledge, hemodynamic parameters and acute altered state of consciousness have been hypothesized as potential correlates of subsequent antidepressant outcome. A post hoc analysis was performed using the data from an open-label study, in which 39 patients with...

Regional specificity of the cingulate cortex thickness association with the intensity of psilocybin experience: a replication study

Psychopharmacology December 13, 2025 David Greguš, Jaroslav Hlinka, Filip Tylš et al.

Individual variability in psilocybin response is a major challenge for psychedelic-assisted therapy, with structural brain features potentially serving as predictive biomarkers. (Lewis et al. Biomedicines 8(2):34 2020) reported that rostral anterior cingulate cortex thickness predicted emotional experiences under psilocybin, suggesting cortical morphometry as a marker of psychedelic...

Regional Specificity of the Cingulate Cortex Thickness Association with the Intensity of Psilocybin Experience: A Replication Study

Research Square September 25, 2025 David Greguš, Jaroslav Hlinka, Filip Tylš et al.

Abstract Rationale: Individual variability in psilocybin response is a major challenge for psychedelic-assisted therapy, with structural brain features potentially serving as predictive biomarkers. Lewis et al. (2020) reported that rostral anterior cingulate cortex thickness predicted emotional experiences under psilocybin, suggesting cortical morphometry as a marker of psychedelic...

The phenomenology of psilocybin's experience mediates subsequent persistent psychological effects independently of sex, previous experience, or setting.

Pharmacological reports : PR June 16, 2025 Tereza Klučková, Marek Nikolič, Filip Tylš et al. 4 citations

Recent studies intensively explore psilocybin's antidepressant potential, but variables like previous experience, repeated use, setting, and sex remain underexplored. This study examines acute and long-term effects of psilocybin in healthy individuals. A double-blind, placebo-controlled, cross-over study included 40 healthy participants (20 females, mean age 38). Each received two doses of...

Psilocybin—Mediated Attenuation of Gamma Band Auditory Steady-State Responses (ASSR) Is Driven by the Intensity of Cognitive and Emotional Domains of Psychedelic Experience

Journal of Personalized Medicine June 19, 2022 Vojtěch Viktorin, Inga Griškova-bulanova, Aleksandras Voicikas et al. 19 citations

Psilocybin is a classical serotoninergic psychedelic that induces cognitive disruptions similar to psychosis. Gamma activity is affected in psychosis and is tightly related to cognitive processing. The 40 Hz auditory steady-state responses (ASSR) are frequently used as indicators to test the ability to generate gamma activity. Based on previous literature, we studied the impact of psilocybin on...

Predictive value of heart rate in treatment of major depression with ketamine in two controlled trials

Clinical Neurophysiology March 14, 2021 Torsten M. Meyer, Martin Brunovský, Jiřı́ Horáček et al. 25 citations

OBJECTIVE: Ketamine has been shown to be effective in treatment of episodes of major depressive disorder (MDD). This controlled study aimed to analyse the predictive and discriminative power of heart rate (HR) and heart rate variability (HRV) for ketamine treatment in MDD. METHODS: In 51 patients, HR and HRV were assessed at baseline before and during ketamine infusion and 24 hours post...

The Effects of Daytime Psilocybin Administration on Sleep: Implications for Antidepressant Action

Frontiers in Pharmacology December 3, 2020 Daniela Dudysová, Karolína Janků, Michal Šmotek et al. 37 citations

Serotonergic agonist psilocybin is a psychedelic with antidepressant potential. Sleep may interact with psilocybin’s antidepressant properties like other antidepressant drugs via induction of neuroplasticity. The main aim of the study was to evaluate the effect of psilocybin on sleep architecture on the night after psilocybin administration. Regarding the potential antidepressant properties, we...

The Antidepressant Effect of Ketamine Is Dampened by Concomitant Benzodiazepine Medication

Frontiers in Psychiatry August 28, 2020 Veronika Andrashko, Tomáš Novák, Martin Brunovský et al. 46 citations

The rapid antidepressant effect of ketamine has become a breakthrough in the research and treatment of depression. Although predictive and modulating factors of the response to ketamine are broadly studied, little is known about optimal concurrent medication protocols. Concerning gamma-aminobutyric acid neurotransmission being a shared target for both ketamine and benzodiazepines (BZD), we...
