The Motivation for Performing Ecstatic Rituals (A Case Study of Sufi Sama and Similar Rituals in Shamanism)

ادبیات عرفانی September 17, 2026 Haniye Pakravan, Ehsan Reisi

Ecstatic rituals are regarded as among the oldest religious concepts across diverse cultures. These rituals occupy a central and foundational position within certain spiritual traditions and belief systems, while in other religious or cultural contexts, they are rejected or marginalized. In several intellectual and faith-based traditions, trance is understood as a form of altered consciousness...

The Functional Connectivity of Hallucinations in Psychiatric Disorders and Neurodegenerative Disorders: A Systematic Review

September 16, 2026 Yifan Ren, Huyen Ngoc Pham, Xiong Xiong et al. preprint

Background: Hallucinations span psychiatric and neurodegenerative disorders, yet unified neurobiological or consciousness-based explanations remain uncertain. Functional connectivity (FC) provides a network-level view with highly heterogeneous findings.Methods: Following PRISMA, we included studies with FC of hallucinations to ask whether it is sensitive to hallucinations, can distinguish...

Local and interregional thalamocortical dynamics show temporally dissociable changes during propofol induced loss of consciousness.

Neuroimage September 14, 2026 Luxin Fan, Xin Wen, Fa Lu et al.

Whether propofol-induced loss of consciousness (LOC) reflects a single thalamocortical transition or involves temporally dissociable local and interregional dynamics remains unclear. Using stereo-electroencephalography recordings from the anterior nucleus of the thalamus, prefrontal cortex, and temporal cortex during anesthesia induction, we quantified permutation entropy, spectral power,...

Cultural incorporation in Nietzsche’s middle period

Warwick Research Archive Portal September 13, 2026 David Rowthorn

In this dissertation I defend the claim that Nietzsche’s middle period can be read as presenting a theory of cultural flourishing that has as its foundation the project of incorporating truth. The consciously experienced world is the product of a number of interpretive processes operating below the level of consciousness. The intentional structure of experience is universal to human beings, but...

Exploring the interplay between interoception and dissociative experiences: insights from a non-clinical population

Scientific Reports September 13, 2026 Gabriele Vercelli, Sofia Ciccarone, Anand Rai et al.

Alterations in interoception have been implicated in several neurological and psychiatric conditions, including those involving dissociative tendencies. Thus, investigating the link between interoception and dissociation may shed light on the mechanisms supporting self-consciousness and its disturbances. Here, we investigated whether interoception was associated with trait and experimentally...

From Operational Indexing to Experiential Localization: A Comparative Organizational Framework for Probabilistic Inference about Animal Consciousness

Zenodo (CERN European Organization for Nuclear Research) September 13, 2026 John Cantellow preprint

This paper develops Experiential Localization (EL) as a comparative organizational framework for probabilistic inference concerning animal consciousness. The central problem is that experiential accessibility cannot be directly observed across species, while behavioural and biological evidence can nevertheless alter confidence among competing interpretations. The framework distinguishes...

What Kafka's Metamorphosis reveals about consciousness without communication.

Brain Communications September 11, 2026 Alexis Demas

What Kafka's Metamorphosis reveals about consciousness without communication Gregor Samsa awakens transformed. His body has become unrecognizable, his movements incoherent and his voice unintelligible. Yet nothing in his inner life appears altered. He thinks clearly, remembers precisely and understands his situation with painful lucidity. From the opening lines of The Metamorphosis,...

From Menarche to the Sacred: Girls' Puberty Rites and the Prehistoric Origins of Religion

Knowledge Commons (Lakehead University) September 11, 2026 Darshi Arachige

This article synthesises a framework positioning the cross-cultural practice of secluding girls at puberty as a forerunner to institutionalised religion, tracing its structural roots deep into the Upper Palaeolithic. Integrating ethnographic documentation, portable art, parietal cave art, and socio-cultural history — including European shamanism and the witch cult — the synthesis argues for an...

Joint perception biases subjective awareness reports.

Journal of Experimental Psychology General September 10, 2026 Benjy Barnett, Daniel Yon

Humans are fundamentally social creatures, yet how our social context modulates perceptual decision making remains unknown.In a joint decision-making paradigm, we examined whether participants' subjective awareness reports in a perceptual detection task are influenced by the awareness reports of a computerized partner.Across multiple experiments, we reveal that participants match their...

722. Predictors of therapeutic response to LSD in anxiety: short- and long-term outcomes

The International Journal of Neuropsychopharmacology September 9, 2026 Friederike Holze, F Müller, Peter Gasser et al.

Abstract Background Anxiety disorders are a major health burden and current treatment options yield unsatisfactory results. Psychedelics, such as lysergic acid diethylamide (LSD) that act via agonism on serotonin 2A receptors, have recently been shown to be effective in the treatment of anxiety symptoms. Aims & Objectives Here, we determine the relationship between the acute experience and...
