Research into new treatments for neuropsychiatric disorders has progressed slowly over the past 50 years, with limited breakthroughs. However, the psychedelic renaissance is opening promising new avenues for therapy, offering the potential to reduce side effects and eliminate the need for chronic use of traditional antidepressants. A key goal in neuropharmacology today is to understand the role...
Serotonergic psychedelics enhance neurophysiological complexity and the repertoire of brain states, whereas general anesthetics produce opposite effects. Serotonergic psychedelics are also known to increase wakefulness and reduce sleep time in rodents. Therefore, we hypothesized that 2,5-dimethoxy-4-iodopamphetamine (DOI), a serotonergic psychedelic, will reverse general anesthesia and restore...
Introduction: Serotonergic psychedelics, serotonin 2A receptor agonists such as psilocybin that can result in substantially altered states of consciousness, are used in recreational and research settings. The safety of psychedelic experiences in research settings is supported by controlled physical environments, presence of clinical and medical staff to address emergent issues, screening for...
Psychedelics engage the serotonergic system as potent neuromodulators, increasing neuroplasticity in humans and rodents. Persistent changes in cognitive flexibility, emotional regulation, and social cognition are thought to underlie the therapeutic effects of psychedelics. However, the underlying molecular and cellular basis of psychedelic-induced plasticity remains unclear. Here, we identify...
Exploration of the potential of serotonergic psychedelic drugs, such as psilocybin and LSD, as potential treatments for headache disorders. This review addresses the need for well-informed physician guidelines and discusses mechanisms, safety, and efficacy of these treatments. Further research, including the consideration of combination with psychotherapy, is needed. Psychedelics demonstrate...
MDMA or 3,4- methylenedioxymethamphetamine is a psychoactive substance, exhibiting mild hallucinogenic properties, that became widely known as a recreational party drug. However, its ability in helping individuals access deeply rooted emotions has prompted significant interest in its potential applications within clinical practice. MDMA’s mechanism of action involves increasing the release of...
Treatment of Parkinson's disease (PD) has remained largely unchanged and focuses primarily on symptomatic relief through activation of dopaminergic pathways. Currently, there are no proven prophylactic approaches to the prevention of PD. This systematic review seeks to compare two separate compounds, metformin (MTF) and psilocybin, as potential prophylactic therapeutics against the development...
Psychedelic drugs are increasingly visible in society once more, but their risks and adverse effects have received less attention than perhaps they should. While fatalities associated with psychedelics appear rare, a systematic approach to characterising their aetiology is required to inform harm minimisation efforts. This study aimed to analyse prevalence and characteristics of...

Psychedelics have emerged as a promising approach to treating mental disorders, challenging traditional paradigms in psychiatry. This study conducted an integrative literature review to investigate the advances, challenges, and implications of the therapeutic use of these substances, addressing the guiding question: “What are the current scientific perspectives on the use of psychedelics in the...
Abstract Despite enormous interest in psychedelics for psychiatric interventions, potential underlying biological mechanisms remain unclear. Here, we confirm that a single dose of psilocybin increases synaptic transmission in mouse medial prefrontal cortex. Using scRNA-sequencing, we identify cell-type specific mechanisms of sustained neuroplastic effects. We show that, 24h post-psilocybin,...
