Virtual reality has recently been utilized in a therapeutic tool within the area of psychotherapy. VR therapy has become a significant approach to a number of psychological disorders such as anxiety, PTSD, and depression through exposure therapy and simulated environments (Park et al., 2019). However, the potential to mimic psychedelic experiences through VR simulations as a therapeutic...

ABSTRACT Neural synchrony and functional connectivity are disrupted in neuropsychiatric disorders such as schizophrenia. However, these alterations and how they are affected by commonly prescribed neuropsychiatric medication have not been characterized in depth. Here, we investigated changes in neural dynamics of circuits involving the prefrontal cortex and the hippocampus during psychosis...

Abstract Depression is a debilitating psychiatric disorder affecting millions worldwide. The Chronic Unpredictable Mild Stress (CUMS) model is widely used to simulate depression-related behavioural and neurobiological changes in rodents. This study evaluated the antidepressant-like effects of harmaline, a monoamine oxidase (MAO) inhibitor derived from Peganum harmala , in comparison to...

Psychedelics, contemplative practice, and fasting are physiologically unrelated interventions that nevertheless converge, across cultures and centuries, on a common experiential endpoint: the mystical state. Here I propose that this convergence reflects shared disruption of a single computational architecture, the precision-weighted predictive hierarchy, through three mechanistically distinct...

Post-traumatic stress disorder (PTSD) is a debilitating mental health disorder that causes significant dysfunction in individuals. Currently, there are many approved Pharmacotherapy and Psychotherapy treatment options for PTSD, but unfortunately, half of the patients do not respond to traditional therapies. In this article, we reviewed clinical trials and research on...

Abstract Introduction: Lysergic acid diethylamide (LSD) is an artificial hallucinogenic drug. Thus, we hypothesized that LSD might act 5-HT4 serotonin receptors and/or H2 histamine receptors. Methods: We studied isolated electrically stimulated left atrial preparations, spontaneously beating right atrial preparations, and spontaneously beating Langendorff-perfused hearts from transgenic mice...

Abstract Maternal depression during pregnancy adversely affects offspring neurodevelopment and behaviour. Typical antidepressants like selective serotonin reuptake inhibitors have limitations due to risks of crossing the placenta. Ketamine has emerged as a promising alternative treatment. This research examined ketamine's effects on offspring of maternally stressed mice. Dams were divided into...

Understanding how a simple endogenous tryptamine could occasion profound alterations in perception and self-modeling remains a key challenge for neuroscience. We advance the Birth Echo Hypothesis (BEH) : during a narrowly defined perinatal window (≈ −2 to +24 h around delivery), a convergence of hypoxic–hypercapnic stress, maximal sensory novelty, and a poly-neuromodulatory milieu...

Background: 5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT), also officially known as Mebufotenin, is a naturally occurring serotonergic psychedelic alkaloid found in the venom of the Sonoran Desert toad (Incilius alvarius) and various plant species. Areas of Uncertainty: Trace levels of 5-MeO-DMT may be produced endogenously in humans, but its physiological role remains unclear. Safety profiles...

Background: N,N-dimethyltryptamine (DMT) is a naturally-occurring serotonergic psychedelic found in natural plants around the globe. As the main psychoactive component in ayahuasca, which also contains monoamine oxidase (MAO) inhibitors, DMT has been consumed as plant-based brew by indigenous peoples for centuries. Further research is required to delineate the therapeutic utility of DMT.Areas...
