Building Blocks for the Development of a Self-Consistent Electromagnetic Field Theory of Consciousness.

Frontiers in Human Neuroscience September 28, 2021 Joachim Keppler

The goal of this work is to compile the basic components for the construction of an electromagnetic field theory of consciousness that meets the standards of a fundamental theory. An essential cornerstone of the conceptual framework is the vacuum state of quantum electrodynamics which, contrary to the classical notion of the vacuum, can be viewed as a vibrant ocean of energy, termed zero-point...

Суицидальный кризис: ангелы рядом

Суицидология September 27, 2021 А.р. Озкан

В статье на основе эпидемиологических и качественных (самоописания) данных с иллюстрациями из нонфикшн и художественной литературы и кинематографа серия случаев суицидального кризиса и незавершённого суицида представлена как континуум состояний измененного сознания с мистико -религиозным содержанием в жизнеопасных условиях с постсуицидальными состояниями по типу «новой жизни».Ключевые слова:...

‘I Get High With a Little Help From My Friends’ - How Raves Can Invoke Identity Fusion and Lasting Co-operation via Transformative Experiences

Frontiers in Psychology September 24, 2021 Martha Newson, Ragini Khurana, Freya Cazorla et al. 48 citations

Psychoactive drugs have been central to many human group rituals throughout modern human evolution. Despite such experiences often being inherently social, bonding and associated prosocial behaviors have rarely been empirically tested as an outcome. Here we investigate a novel measure of the mechanisms that generate altered states of consciousness during group rituals, the 4Ds: d ance, d rums,...

Psychedelics use predicts more positive emotional reactivity and diminished outward-focused self-consciousness: the mediating role of ego dissolution and mystical experiences

September 23, 2021 Paweł Orłowski, Anastasia Ruban, Jan Szczypiński et al. preprint

Background: Psychedelics are able to acutely alter emotional reactivity and self-consciousness. However, whether regular, naturalistic use of psychedelics can be linked to more persistent, trait-level changes in these domains remains an open question.Aim: To test three hypotheses: i) psychedelics use is related to higher positive and lower negative emotional reactivity; ii) psychedelics use is...

Neuropsychological Functioning in Users of Serotonergic Psychedelics – A Systematic Review and Meta-Analysis

Frontiers in Pharmacology September 16, 2021 Lukas A Basedow, Thomas Riemer, Simon Reiche et al. 16 citations

Background: Serotonergic psychedelics (SPs) like LSD, psilocybin, DMT, and mescaline are a heterogeneous group of substances that share agonism at 5-HT 2a receptors. Besides the ability of these substances to facilitate profoundly altered states of consciousness, persisting psychological effects have been reported after single administrations, which outlast the acute psychedelic effects. In...

Default mode network and attention network in unconscious processing

Proceedings of the 2021 IEEE International Conference on Human Machine Systems Ichms 2021 September 8, 2021

The critical role of unconscious processing in problem solving had been proved by previous empirical evidence. However, we still could not understand how unconscious mind process information differently from the conscious mind. One previous study utilized an event-related potential approach to demonstrate the different processes we went through during processing unconscious cue and conscious...

The Role of Psilocybin-Assisted Psychotherapy to Support Patients With Cancer: A Critical Scoping Review of the Research

Journal of Holistic Nursing September 6, 2021 Rebecca H Lehto, Megan Miller, Jessica Sender 16 citations

Treatments for addressing psychiatric mental health issues in vulnerable patients with cancer are established. Yet, many patients persist with unrelenting psychological difficulties despite intervention. There is growing interest in the role of psilocybin-assisted psychotherapy for managing treatment-resistant mental health challenges in patients with cancer. Psilocybin is a naturally occurring...

Magic: A Theoretical Reassessment†

Anthropology of Consciousness September 1, 2021 Michael Winkelman

AbstractAnthropological theories about the techniques broadly labeled magic and related practices as sorcery, witchcraft, divination, and ritual curing are in need of reformulation. Theoretical considerations of these phenomena within anthropology have neglected to consider the basic assumptions of magical belief, instead departing from Western cultural assumptions that beliefs about magic are...

Psilocybin-induced changes in brain network integrity and segregation correlate with plasma psilocin level and psychedelic experience.

European Neuropsychopharmacology September 1, 2021 Martin K Madsen, Dea S Stenbæk, Albin Arvidsson et al. 132 citations

The emerging novel therapeutic psilocybin produces psychedelic effects via engagement of cerebral serotonergic targets by psilocin (active metabolite). The serotonin 2A receptor critically mediates these effects by altering distributed neural processes that manifest as increased entropy, reduced functional connectivity (FC) within discrete brain networks (i.e., reduced integrity) and increased...
