Currently, no effective treatment exists for injuries at the interface between the CNS/PNS, largely due to their complex pathophysiology and the limited efficacy of single-target therapies. To address this challenge, we investigated a novel combinatorial therapeutic strategy integrating surgical VRR with fibrin sealant biopolymer (FSB) and DMT in a rat model of ventral root avulsion VRA. DMT...
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...
N,N-dimethyltryptamine (DMT) is a fast-acting psychedelic drug that induces a radical reorganization of conscious contents and brain dynamics. However, our understanding of how brain dynamics support psychedelic-induced conscious states remains unclear. We therefore present a repeated-measures dose-dependent study of the subjective and neural dynamics induced through DMT under naturalistic...

Clinical trials using 5-MeO-DMT to treat various mental health conditions are currently underway, however research on 5-MeO-DMT use in humans is limited. To date, no scoping review of the published, peer-reviewed literature exists. The purpose of the present analysis is to examine the extent, range, and nature of peer-reviewed research on the use of 5-MeO-DMT in humans and, ultimately, to...
El presente trabajo de investigación tuvo como objetivo identificar, analizar, conglomerar y describir los efectos relatados de la experiencia en personas que consumen o han consumido dimetiltriptamina (DMT) en cualquiera de sus métodos de administración, así como examinar su uso potencial como auxiliar terapéutico. Las técnicas de índole metodológica empleadas fueron la investigación...
Psychedelics lead to profound changes in subjective experience and behaviour, which are typically conceptualised in psychological terms rather than corresponding to an altered brain state or a distinct state of vigilance. Here, we performed chronic electrophysiological recordings from the neocortex concomitant with pupillometry in freely moving adult male mice following an injection of a...
Festival in the state of Bahia, a Umbanda terreiro in Pernambuco and a Catimbó ritual in Rio Grande do Norte. The first experience was provided by a smokable version known as changa that became popular among psychonauts. Changa is supposed to have been invented in Australia, but using acacia instead of jurema as the source of DMT, a preparation also referred to as “aussiewaska,” according to...
Classical psychedelics such as N,N-dimethyltryptamine (DMT) 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 ayahuasca—oral DMT induces a psychedelic experience lasting 4–5 h. While some neuroimaging...
Psychedelic compound N,N-Dimethyltryptamine (DMT) is renowned for inducing highly immersive experiences, often including encounters with seemingly sentient presences. While such phenomena are well documented, immersion under psychedelics remains conceptually underdefined and phenomenologically underexplored. Here we apply micro-phenomenology to characterize immersion under DMT as a structured...
Reports of near-death experiences (NDEs), end-of-life visions (ELVs), and culturally embedded afterlife narratives frequently describe profoundly positive or distressing states. Traditional interpretations treat these phenomena as evidence of external metaphysical realms. The Dying-Moment Dream Hypothesis proposes an alternative, neurobiologically grounded explanation: that culturally...
Under the influence of psychedelics, people often report encountering "entities" who seem to have their own autonomous agency. Depending on the cultural milieu, these entities are reported to take a variety of forms, including spirits, elves, ancestors, or fragments of the self. Encounters with such beings hold a central place in many traditions of psychedelic practice around the world. And...
