Abstract Ibogaine is an indole alkaloid derived from the root bark of Tabernanthe iboga. The anti-addictive actions of ibogaine were first reported in the 1960s by persons using heroin. They offered personal testimonials that single oral doses of ibogaine abruptly blocked opioid withdrawal, and they remained drug-free after ibogaine exposure. Today, online forums describe ibogaine use for...

During binocular rivalry, conflicting images are presented one to each eye and perception alternates stochastically between them. Despite stable percepts between alternations, modeling suggests that neural signals representing the two images change gradually, and that the duration of stable percepts are determined by the time required for these signals to reach a threshold that triggers an...
Abstract Interest in psychedelics is increasing due to potential for improved mental health and quality of life. However, adverse effects on mental health are still a concern. Personality traits have been suggested to both influence the psychedelic experience and mental health, and even be changed by psychedelic use. The present study describes for the first time a national sample of Swedish...
Introduction: With the progressive advancement of clinical and experimental trials aimed at investigating the pharmacotherapeutic potential of psychedelic substances, there is also the development of other conceptions of use, not only for the treatment of psychiatric disorders, but also for the improvement of emotional/cognitive functions. Objective: The present study is a systematic review of...
Abstract Psilocybin has shown promise for alleviating symptoms of depression and is currently in clinical trials for the treatment of anorexia nervosa (AN), a condition that is characterised by persistent cognitive inflexibility. Considering that enhanced cognitive flexibility after psilocybin treatment is reported to occur in individuals with depression, it is plausible that psilocybin could...
Recent trials of psychedelic-assisted therapy have suggested potential efficacy for the treatment of many health conditions that disproportionately impact sexual and gender minority (SGM) people, including major depressive disorder and alcohol and tobacco use disorders. Despite these promising findings, the potential benefits of psychedelics for SGM people have been largely ignored. First, we...
Abstract Resting state (RS) brain activity is inherently non-stationary. Hidden Semi-Markov Models (HsMM) can characterize the continuous RS data as a sequence of recurring and distinct brain states along with their spatio-temporal dynamics. Recent explorations suggest that EEG brain state dynamics in the alpha frequency link to auditory hallucination proneness (HP) in non-clinical individuals....
Treatment of psychiatric disorders with psychedelic substances represents one of the most promising current treatment approaches in psychiatry. Since its inception in the 1950s, therapy with psychedelics has been conceptualised as psychedelic-assisted psychotherapy-ie, a form of psychotherapy that uses the profound biological effects of this class of substances as a catalyst for changing...
Research on psychotropics is gaining more popularity worldwide and support from drug regulatory agencies, which recognise the unmet medical needs of certain patient communities, such as patients with mental disorders and patients with cancer who experience depression. Cannabinoids and psilocybin have shown promising results in preclinical studies and clinical trials, but the current clinical...
