Diverse explanations or theories of consciousness are arrayed on a roughly physicalist-to-nonphysicalist landscape of essences and mechanisms. Categories: Materialism Theories (philosophical, neurobiological, electromagnetic field, computational and informational, homeostatic and affective, embodied and enactive, relational, representational, language, phylogenetic evolution); Non-Reductive...
Classic psychedelics are able to profoundly alter the state of consciousness and lead to acute experiences of ego dissolution - the blurring of the distinction between representations of self and the external world. However, whether repeated use of psychedelics is associated with more prolonged and permanent modifications to the concept of self remains to be investigated. Therefore, we...
Ketamine is a dissociative anesthetic that induces a shift in global consciousness states and related brain dynamics. Portable low-density EEG systems could be used to monitor these effects. However, previous evidence is almost null and lacks adequate methods to address global dynamics with a small number of electrodes. This study delves into brain high-order interactions (HOI) to explore the...
Purpose Psychedelic drugs can induce altered states of consciousness characterised by changes in visual perception, tactile sensation, cognition, and emotion. Although there is a history of misinformation surrounding these drugs, recent investigation has reinvigorated interest. However, little research has assessed the attitudes of psychedelic consumers regarding these substances. The current...
The quality space hypothesis about conscious experience proposes that conscious sensory states are experienced in relation to other possible sensory states. For instance, the colour red is experienced as being more like orange, and less like green or blue. Recent empirical findings suggest that subjective similarity space can be explained in terms of similarities in neural activation patterns....
Time can be a difficult concept to understand. Albert Einstein, who viewed time as an illusion, explained the passage of time is relative to the observer’s frame of reference in the space-time continuum. However, the state of consciousness of the observer also influences the passage of time. This paper examines the relationship between the experience of time and different states of...
Meditation, psychedelics, and other similar practices or induction methods that can modulate conscious experience, are becoming increasingly popular in clinical and non-clinical settings. The phenomenology associated with such practices or modalities is vast. Many similar effects and experiences are also reported to occur spontaneously. We argue that this experiential range is still not fully...
Dans cet article, nous avons pour objectif de décrire un modèle interdisciplinaire de psychothérapie assistée par psychédéliques (PAP) que nous avons développé dans un cadre institutionnel aux hôpitaux universitaires de Genève. La psychothérapie assistée par psychédéliques (PAP) est une approche psychothérapeutique exploitant l’altération de l’état de conscience induite par une substance...
Cannabis is an annual herb of the genus Cannabis, with a history of medical use going back thousands of years. However, its abuse causes many side-effects, including confusion of consciousness, alienation, and mental disorders such as schizophrenia and depression. Research conducted on rodents suggests that there are two types of cannabinoid receptors-cannabinoid receptor 1 (CB1R) and...
The article discusses the idea of the plurality of worlds of human consciousness and animal psyche from the perspective of the conception of enactivism, philosophical phenomenology and complexity theory. It is shown that the multiversality of consciousness can be associated not only with its different states (sleep, wakefulness, extreme and altered states, personal and transpersonal...
