Depression, a common mental disorder, affects people at different stages of life.Classic antidepressant treatment is generally effective, however, it is prolonged.Nonetheless, numerous patients who undergo various classic antidepressant therapies still suffer from depression.Therefore, the search for novel medications is essential.In this review, we explore ...
This study will test the hypothesis that brain systems are differentially regulated by serotonin in individuals with and without Autism Spectrum Disorder. To do this, the brain response to two single acute doses of partial serotonin (5HT)1A/2A receptor agonist psilocybin (COMP360) relative to a single dose of placebo (baseline serotonin activity) will be com...
Abstract Classical psychedelics such N,N -dimethyltryptamine (DMT), psilocybin, and lysergic acid diethylamide (LSD) modulate consciousness via serotonergic receptor agonism, and are increasingly investigated for their psychotherapeutic potential. When combined with the monoamine oxidase A (MAO-A) inhibitor harmine-mimicking the pharmacological profile of ay...
Sleep paralysis (SP), an REM parasomnia, can be characterized as one of the symptoms of narcolepsy. The SP phenomenon involves regaining meta-consciousness by the dreamer during REM, when the physiological atonia of skeletal muscles is accompanied by visual and auditory hallucinations that are perceived as vivid and distressing nightmares. Sensory impression...
The resurgence of psychedelic-assisted psychotherapy marks a pivotal evolution in mental health treatment, challenging traditional paradigms by integrating compounds such as psilocybin, LSD, MDMA, and ketamine into clinical practice. Historically marginalized due to regulatory and societal concerns, these agents are now gaining recognition for their unique n...
This viewpoint reconceptualizes mysticism and fundamentalism as brain network disorders, with psychedelics like psilocybin, lysergic acid diethylamide, and N,N-dimethyltryptamine offering potential to modulate these states. By disrupting rigid neural patterns, psychedelics may foster cognitive flexibility, challenge inflexible belief systems, and offer thera...
The classical psychedelics (+)-lysergic acid diethylamide (LSD), psilocybin, and mescaline exert their psychedelic effects via activation of the 5-HT2A serotonin receptor (5-HT2AR). Recent clinical studies have suggested that classical psychedelics may additionally have therapeutic potential for many neuropsychiatric conditions including depression, anxiety,...
The therapeutic potential of psychedelic substances, particularly psilocybin, for treatment-resistant depression (TRD) has garnered considerable attention. However, the necessity of subjective psychedelic experiences for therapeutic efficacy remains unclear, creating a critical gap in the field. To determine whether subjective psychedelic experiences induced...
Perception of visual contrast depends on the surrounding spatial context. Typically, the salience of a central target is reduced by a high contrast surrounding stimulus, an effect known as surround suppression. Although this phenomenon is well-studied, the role of specific neurotransmitter systems during surround suppression in human vision remains unclear. ...
Background and HypothesisVisual hallucinations (VH) are a core symptom of both Lewy body diseases (LBDs; e.g., Parkinson’s disease and dementia with Lewy bodies) and serotonergic psychedelics (SPs; e.g., psilocybin and mescaline). While these classes of VH differ in etiology, shared pathways are suggested by overlapping phenomenology and neural mechanisms. T...

Traumatic brain injury (TBI) is a significant global health challenge, with limited effective treatments for its acute and chronic consequences. TBI is characterized by neuroinflammation, oxidative stress, impaired neuroplasticity, imbalances in neurotransmission, and cell death - factors that contribute to the development of neurological and psychiatric dis...
The influence of ovarian hormone fluctuations on neurochemistry, cognition, and psychological responses remains insufficiently examined in current psychedelic research and clinical protocols. Traditional practices and case studies underscore the importance of accounting for these factors in investigations of psychedelic effects. This opinion paper explores t...
BackgroundClassic serotonergic psychedelics are 5-HT2A partial agonists that induce non-ordinary states of consciousness. Many have demonstrated anti-addictive properties; however, their impact on smoking behaviors remains under-researched. This review provides a synthesis of the therapeutic potential of these compounds in promoting smoking cessation and red...
Recent advancements in the study of psilocybin and its active metabolite psilocin have highlighted their unique psychedelic properties and potential therapeutic applications, particularly in the rapid and sustained treatment of depression. However, the potent acute psychedelic effects of psilocybin necessitate a deeper understanding of the neural mechanisms ...
Background Recent years have seen renewed clinical interest in the therapeutic potential of classical psychedelics, such as psilocybin, LSD, DMT, and mescaline. While modern studies have focused on adult populations, adolescents under 18 are routinely excluded due to regulatory, legal, and ethical challenges. Although there exists observational data and hist...
Psilocybin, the naturally occurring psychedelic compound produced by hallucinogenic mushrooms, has received attention due to considerable clinical evidence for its therapeutic potential to treat various psychiatric and neurodegenerative indications. However, the underlying molecular mechanisms remain enigmatic, and few studies have explored its systemic impa...

Major depressive disorder is a debilitating condition, with many patients unresponsive to conventional monoaminergic antidepressants. Rapid-acting antidepressants such as ketamine and psilocybin offer promising alternatives, relieving symptoms within hours. Ketamine, an NMDA receptor antagonist, and psilocybin, a serotonergic psychedelic primarily targeting ...
