There is a growing interest in the medical use of psychedelic substances, as preliminary studies using them for psychiatric disorders have shown positive results. In particular, one of these substances is N, N-dimethyltryptamine (DMT), an agonist serotonergic psychedelic that can induce profound alterations in the state of consciousness. In this work, we use an exploratory tool to reveal...
Understanding alterations of selfhood (termed self-disorders or self-disturbances) that are considered typical of the schizophrenia-spectrum is a central focus of phenomenological research. The currently most influential way of phenomenologically conceiving self-disorders in schizophrenia is as disorders of the so-called most basic or ‘minimal self’. In this paper, we first highlight some...
The purpose of this article is to study the 'sacred' plants, diverse from those exclusively medicinal but with an unquestionable ethnobotanical value because, added to their healing properties, they develop mystical experiences and altered states of consciousness analogous to the ecstatic trance. _Psychoactive_ plants have played an important role in medicine, religion, _ritual_ life, and...
The five articles that comprise the Research Topic were written by scholars from nine countries (i.e., Argentina, Australia, Belgium, Canada, France, Germany, Netherlands, UK, and US) and embody a range of contemporary research foci and methods. Walter and Hinterberger discuss the notion of self-organized criticality (SOC), which is a way of improving system performance through the ability of a...
Psychedelic agents, such as LSD and psilocybin, induce marked alterations in consciousness via activation of the 5-HT2A receptor (5-HT2ARs). We hypothesize that psychedelics enforce a state of synthetic surprise through the biased activation of the 5-HTRs system. This idea is informed by recent insights into the role of 5-HT in signaling surprise. The effects on consciousness, explained by the...
Abstract Background Depression is a major global health challenge, affecting over 300 million people worldwide. Current pharmacological and psychotherapeutic interventions have limited efficacy, underscoring the need for novel approaches. Emerging evidence suggests that peak emotional experiences characterized by awe, transcendence, and meaning hold promise for rapidly shifting maladaptive...
The article presents a critical evaluation of the Gateway Process, a neurological training system developed in 1983 by the Central Intelligence Agency (CIA) and the United States Army to harness human brainwave output and measure altered states of consciousness using innovative audio technologies. Initially classified, the Gateway Process training system was designed to enhance cognition...
Background Psychedelic-assisted therapies hold early promise for treating multiple psychiatric conditions. However, absent standards for the care, teams providing psychedelic-assisted therapy pose a major roadblock to safe administration. Psychedelics often produce spiritually and existentially meaningful experiences, and spiritual health practitioners have been involved in administering...
The question of whether artificial intelligence (AI) can be considered conscious and therefore should be evaluated through a moral lens has surfaced in recent years. In this paper, we argue that whether AI is conscious is less of a concern than the fact that AI can be considered conscious by users during human-AI interaction, because this ascription of consciousness can lead to carry-over...
The neurobiology of conscious experience is one of the fundamental mysteries in science. New evidence suggests that transcranial magnetic stimulation of the parietal cortex does not modulate bistable perception. What does this mean for the neural correlates of consciousness, and how should we search for them?
