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 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...
Renewed scientific interest in psychedelic compounds represents one of the most promising avenues for addressing the current burden of mental health disorders. Classic psychedelics are a group of compounds that exhibit structural similarities to the naturally occurring neurotransmitter serotonin (5-HT). Acting on the 5-HT type 2A receptors (5-HT2AR), psychedelics induce enduring...
Conventional antidepressants show moderate efficacy in treating major depressive disorder. Psychedelic-assisted therapy holds promise, yet individual responses vary, underscoring the need for predictive tools to guide treatment selection. Here, we present graphTRIP (graph-based Treatment Response Interpretability and Prediction) – a geometric deep learning architecture that enables three...
