A Study of the Therapeutic Benefits and Physiological Effects of Yoga Nidra

Gyanshauryam International Scientific Refereed Research Journal September 20, 2026 Surbhi Agrawal

In the modern lifestyle, human health is being adversely affectedboth physically and mentallyby constantly rising mental stress, a sedentary routine, and work-related pressure. Against this backdrop, 'Yoga Nidra' from the Indian yogic tradition has emerged as a highly effective psychosomatic technique, regarded by Swami Satyananda Saraswati as being equivalent to Pratyahara. This practice...

The Neural Architecture of Aesthetic Cognition: A Predictive-Processing Essay in Support of the TransformativeArts Framework

Arts September 19, 2026 Scott Thomas Carter

The TransformativeArts Framework (TAF) holds that the neural systems recruited to make and perceive art are not peripheral modules but expressions of the core architecture of thought. This essay asks whether contemporary neuroscience supports that claim, and it identifies three observations that the predictive-processing literature on the arts has not yet made. Peer-reviewed neuroscience from...

Cerebellar Alteration in Resting-State Functional Connectivity Among Kratom ( Mitragyna speciosa ) Users: Insights from Functional MRI

Journal of Psychoactive Drugs September 18, 2026 Suzana Mat Isa, Aini Ismafairus Abd Hamid, Muhamad Zabidi Ahmad et al.

), further studies are needed to measure its neurobiological impacts. This exploratory study employed resting-state functional magnetic resonance imaging (rs-fMRI) to examine alterations in brain activity and functional connectivity (FC) among kratom users. A total of 43 respondents were recruited (22 regular kratom users and 21 healthy controls). RS-fMRI data were acquired using a 1.5T GE...

The impact of an app-delivered mindfulness-based intervention on resting-state functional connectivity in pediatric concussion: a pilot study

Frontiers in Neuroscience September 17, 2026 Olivier Brown, Andra M. Smith, Molly Cairncross et al.

Rationale Concussion disrupts brain connectivity, and effective treatments remain limited. Mindfulness-based interventions (MBIs) may influence functional connectivity (FC) of networks affected by concussion, but pediatric trials are lacking. This study investigated whether an app-delivered MBI produced greater FC changes than a sham condition across the default mode (DMN), salience (SN), and...

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...

Two Modes of Consciousness Introduction

Zenodo (CERN European Organization for Nuclear Research) September 16, 2026 Mart Wijn preprint

Abstract This paper introduces a simple distinction that may change how we think about consciousness. It proposes that human beings operate in two fundamentally different modes. Type 1 is direct awareness — experiencing reality without commentary. Type 2 is narrative consciousness — the continuous stream of thinking, interpreting, and self-referencing that most adults experience as their normal...

TIME, DECLINE, AND THE NEUROAESTHETICS OF THE SUBLIME: EMIL CIORAN, OSWALD SPENGLER, AND THE CULTURAL MORPHOLOGY OF CONSCIOUSNESS

Acta Marisiensis Philologia September 15, 2026 Université Libre de Bruxelles, Jan de Maere

This article examines the intersection of Emil Cioran’s phenomenology of temporal decay, Oswald Spengler’s morphological theory of cultural decline, and contemporary neuroaesthetic research grounded in predictive processing and embodied cognition. While both Cioran and Spengler share an intuition of civilisational exhaustion, they articulate decline through distinct epistemological frameworks:...

Correlation of Ketamine and Classic Psychedelics with Pain-Related Neural Connectivity: A Scoping Review of Clinical Experiments on a Potential Therapeutic Target Concerning Ketamine and Classical Psychedelics Administration for Pain Relief

Psychedelic Medicine September 14, 2026 Vasileios Chytas, Georgios Tsimploulis, Dimitrios Chytas

Purpose: Ketamine and classic psychedelics have recently gained increased scientific interest regarding their role in pain management, while there is evidence that pain induces neural connectivity changes. We performed a scoping review to investigate the correlation of ketamine and classic psychedelics with pain-related neural connectivity, aiming to find potential therapeutic targets for these...

Topological integration and segregation of the conscious connectome as biomarkers for state, behavior, and prognosis

Communications medicine September 10, 2026 Sipeng Zhu, Xiaoyu Xu, Qiheng He et al.

Consciousness is hypothesized to emerge from a sophisticated balance between functional integration and segregation across large-scale brain networks. However, how these topological properties are disrupted in disorders of consciousness (DoC), and whether they can predict long-term recovery, remain to be established. Using resting-state functional MRI and graph-theoretical modeling in patients...

Multilevel Mechanisms and Clinical Efficacy of Psilocybin in Depression Treatment: A Systematic Review

International Journal of Molecular Sciences September 10, 2026 Xizhen Zhang, Xiaowen Zhang, Haiyu Zhang et al.

Depression, characterized by persistent low mood and anhedonia, represents a prevalent affective disorder imposing substantial medical and economic burdens. Current first-line antidepressants are limited by delayed onset and treatment resistance. Psilocybin (PSI) has re-emerged as a promising therapeutic agent with rapid, sustained antidepressant effects. This systematic review was conducted...
