In the immense realm of the human mind, there is a border territory between light and darkness, we will find that consciousness transforms and expands beyond the limits of the everyday. This very little explored territory is inhabited by altered states of consciousness, a phenomenon that has generated all kinds of intrigue for philosophers, scientists and spiritual seekers throughout history...
Despite the longstanding use of nitrous oxide and descriptions of its psychological effects more than a century ago, there is a paucity of neurobiological investigation of associated psychedelic experiences. We measure the brain's functional geometry (through analysis of cortical gradients) and temporal dynamics (through analysis of co-activation patterns) using human resting-state functional...
Recent years have seen a global explosion in the field of psychedelic research, popularizing of use of non-ordinary states of consciousness to aid in PTSD, anxiety and depression, end of life and a growing sense that the use of substances like MDMA, psilocybin and others may become mainstream approaches to treating persistent challenges in these marginalized populations.As we destigmatize these...
Abstract Here, we describe how Casas Grandes Medio period (AD 1200 to 1450) shamanic practices of the North American Southwest used tobacco shamanism, a ritual stance called the Tennessee Diviner (TD) posture, and cultural expectations to generate trance experiences of soul flight and divination. We introduce a conceptual model that holds that specific trance experiences are the emergent result...
Abstract In 1960s American science fiction, representations of altered consciousness may function as a novum, framing how protagonists perceive and interact with the storyworld, motivating their actions, and estranging readers. Representations of these states are rooted in the lexical particulars of style, which became of central concern to the rising New Wave subgenre. As a result of the...
Background: The interest in psychoactive agents for treating mental disorders has gathered a growing body of scientific interest. However, research on the relationship between altered states of consciousness (ASCs) and ketamine's antidepressant properties is still limited. Likewise, approaches to sustain early treatment success for the long-term are needed. Taking both aspects into account, the...
Ketamine commonly and rapidly induces dissociative and other altered states of consciousness (ASCs) in humans. However, the neural mechanisms that contribute to these experiences remain unknown. We used functional neuroimaging to engage key regions of the brain’s affective circuits during acute ketamine-induced ASCs within a randomized, multi-modal, placebo-controlled design examining placebo,...
Due to the increasing availability and efficiency of digital technologies humanity has reached a point where digitally altering consciousness might become ubiquitous, echoing in all areas of the functioning of society. In addition to the already familiar functions in terms of conveying information, enabling experiences, and extending our realities, there is an emerging field of...
Self-induced cognitive trance (SICT) is a voluntary non-ordinary state of consciousness characterized by a lucid yet narrowed awareness of the external surroundings. It involves a hyper-focused immersive experience of flow, expanded inner imagery, modified somatosensory processing, and an altered perception of self and time. SICT is gaining attention due to its potential clinical applications....
Objective: Engaging in practices of intimacy meant to develop and sustain intimacy can be beneficial for couples. Psychoactive substances such as 3,4-Methylenedioxymethamphetamine (MDMA) have shown to facilitate bonding within couples and it is hypothesised that classic psychedelics, due to their property to increase prosocial behaviours, can similarly promote interactional intimacy. This study...
Research with hallucinogens suggests that non-ordinary states of consciousness (NOSCs), particularly mystical-type experiences, predict improvements in various affective disorders and substance use disorders (SUDs). Little is known, however, about the therapeutic potential of NOSCs induced by mind-body practices such as meditation, yoga and breathwork. We conducted a literature review in online...
Autonomous Sensory Meridian Response (ASMR) is an alternative state of consciousness characterised by changes in affect, feelings of relaxation, and tingling sensations on the body. Online videos designed to stimulate ASMR in viewers have become increasingly popular. Although there is evidence that ASMR may improve sleep, emotion regulation, and relaxation, the current understanding of ASMR...
From its very origins, cinema has demonstrated a particular interest in the representation of altered states of consciousness: memories, visions, nightmares and dreams are a common feature of narrative films and usually interrupt a flow of events by inserting different temporalities in the present of the story. Following the arguments explored by Gilles Deleuze in his groundbreaking works on...
Traditional psychedelics, such as LSD, psilocybin, or DMT, are psychoactive compounds that exert their effects mainly through agonism over serotonergic receptors. In appropriate doses and contexts, they produce profound changes in the subjective experience, configuring altered states of consciousness that, upon reaching a critical point, involve the appearance of phenomena of mystical,...
Introduction: Much research has focused on the modeling of the near-death experience (NDE) by classical and atypical psychedelics; however, to date, no study has reported on the relationship between the NDE and the experience induced by the highly potent, endogenous psychedelic drug 5-Methoxy-DMT (5MeO-DMT). This article presents a case study of an individual who is popularly documented to have...
The Altered Xperience Project (AXP) is an ongoing research project that takes the form of an open citizen science initiative. Its main goal is to systematically collect and consolidate data on the subjective experiences induced by various consciousness-manipulating techniques (CMTs). These include both psychoactive substances as well as non-pharmacological manoeuvres that induce altered states...
Indigenous psychologies are informed by their cosmogonies and cosmologies, philosophies, spirituality and religions, traditions and customs, and knowledge and praxis systems. This paper reviews some conceptions of consciousness, psyche, spirit, mental and physical health, relations to all Earth Beings (human and nonhuman), ancestors, nature, and altered states of consciousness among the Nahua...
The healthy conscious brain is thought to operate near a critical state, reflecting optimal information processing and high susceptibility to external stimuli. Conversely, deviations from the critical state are hypothesized to give rise to altered states of consciousness (ASC). Measures of criticality could therefore be an effective way of establishing the conscious state of an individual....
Exploring the neurobiology of the profound changes in consciousness induced by classical psychedelic drugs may require novel neuroimaging methods. Serotonergic psychedelic drugs such as psilocybin produce states of increased sensory-emotional awareness and arousal, accompanied by increased spontaneous electroencephalographic (EEG) signal diversity. By directly stimulating cortical tissue, the...
One of the dominant cultural frames for psychedelics in western culture over last 130 years has been evolutionary spirituality. This tradition suggests human evolution is not finished and can be guided towards the creation of higher beings through such techniques as psychedelics and eugenics or genetic modification. But is everyone evolving into a new species, or just an elite? This essay...
