High Resolution Image Download MS PowerPoint Slide The development of new treatments for neuropsychiatric disorders relies on a deeper understanding of the molecular mechanisms behind psychedelic compounds, particularly how they differentiate between hallucinogenic and antidepressant effects. In this study, we explore by molecular dynamics simulations a series of 25CN-NBx compounds bound to the...

Glaucoma is increasingly recognized as an ischemic neurodegenerative disorder that extends beyond elevated intraocular pressure (IOP) to involve complex vascular, metabolic, and inflammatory mechanisms. Retinal ganglion cells are particularly vulnerable to ischemia-reperfusion injury, oxidative stress, and chronic neuroinflammation, leading to progressive disconnection from central visual...
When Time Stops: Inside the Mind’s Clock is a theoretical preprint monograph exploring how subjective time perception may relate to brain dynamics, informational complexity, and cytoskeletal processes. The work introduces the Scalar Clock Model, in which subjective duration is represented by a scalar variable (φ) whose accumulation rate may be influenced by large-scale neural activity and...
Rodent studies have shown that psychedelic drugs can enhance fear extinction. However, investigations to date have relied on normative aversive conditioning procedures, which limit their relevance to trauma-related memories, as these tend to be overgeneralized and resistant to extinction. Fear extinction depends on activity and plasticity within the infralimbic (IL) region of the medial...
Classic psychedelics, such as psilocybin, lysergic acid diethylamide (LSD), and N,N-dimethyltryptamine (DMT), have emerged as potent modulators of neuroplasticity and metaplasticity in the adult brain, offering novel therapeutic strategies for neuropsychiatric disorders. Recent findings reveal that beyond their transient psychotropic effects, these compounds activate serotonin 5-HT2A receptors...
This preprint presents The Last Dream, a theoretical model aimed at interpreting the subjective experience that may occur in the seconds immediately following cardiac arrest and preceding irreversible neuronal failure. Drawing on convergent evidence from physics of time, neuroscience, neurochemistry, and psychedelic research, the model explores the plausibility of a transient terminal state...
Major depressive disorder (MDD) remains a leading cause of disability worldwide, with current treatments limited by delayed onset and low efficacy. The serotonergic psychedelic N,N-dimethyltryptamine (DMT) has shown rapid antidepressant effects in early clinical studies, yet its mechanisms and efficacy remain poorly characterized in established models of depression. Here, we evaluated the...
Psilocybin is a psychoactive tryptamine produced by a phylogenetically discontinuous yet ecologically diverse subset of fungi. Despite decades of chemical, pharmacological, and ethnobiological research, the evolutionary forces driving the emergence and persistence of this compound remain insufficiently explained. Recent hypotheses proposing that psilocybin evolved primarily as a deterrent...

Monoamine oxidase inhibitors (MAOIs) remain an important option for patients with treatment-resistant depression (TRD) and other psychiatric conditions, despite potentially serious drug-drug interactions and associated dietary tyramine restrictions. However, they are rarely prescribed in patients with comorbid substance use disorders (SUDs) due to concerns about potential drug interactions and...
The last few decades have been characterised by a resurgence in research and clinical interest in classic serotonergic psychedelics including N,N-dimethyltryptamine (DMT), lysergic acid diethylamide (LSD) and psilocybin, with a growing body of literature pointing to their treatment potential. Ayahuasca is a psychedelic brew commonly composed of plants carrying the psychoactive compound DMT, and...
