Non-unitary reproducibility of an EEG-DMN-like sensor-level proxy: metric-family, task-window and paradigm effects across internally oriented tasks.

Neuroimage September 8, 2026 Salvador Herrera-Pérez, Vanessa Moscardó, Patricia López Mases et al.

Background: Posterior α suppression, frontal θ enhancement and fronto-posterior α-band coupling are routinely interpreted together as an 'EEG-DMN-like' rest-to-task marker. Whether they replicate as a unitary pattern or dissociate across metric families, task windows and cognitive paradigms remains insufficiently characterised within a single harmonised pipeline. Methods: ds004148 (n = 60;...

Before the Proposition: Dependent Origination, Contingency, and the Pre-Symbolic Genesis of Knowing

PhilPapers (PhilPapers Foundation) September 8, 2026 Wanhong Huang

This paper examines the formation of knowing before it becomes stabilized as an explicit proposition, definition, or other symbolic epistemic output. Philosophical and scientific accounts of knowledge frequently privilege articulated results, while the conditions through which those results become epistemically possible receive less attention. The present inquiry focuses on the generative...

How Robustly Can Integrated Information Be Estimated in Artificial Neural Networks?

Zenodo (CERN European Organization for Nuclear Research) September 8, 2026 Sudin Shrestha, Yuvraj Aryal, Devendra Panta et al. preprint

Integrated Information Theory (IIT) identifies consciousness with the intrinsic, irreducible cause–effect power of a physical system, quantified by integrated information Φ, and is therefore often applied to artificial neural networks (ANNs) via scalable proxies. Our central finding is that such proxies are not currently reliable enough to support the comparisons they are used for. We test one...

Long-timescale dynamics shape visual conscious awareness

bioRxiv (Cold Spring Harbor Laboratory) September 8, 2026 Zefan Zheng, Darinka Trübutschek, Yongchun Cai et al. preprint

Abstract Consciousness is mostly studied as if it were composed of independent snapshots, aggregating reports over trials and experimental contexts, disregarding any temporal aspect. However, almost nothing is known about how conscious experience spontaneously fluctuates in time. To shed light on the temporal dynamics of conscious awareness, we evaluated the temporal autocorrelation of...

Dose-dependent effect of ketamine on functional connectivity in mice

bioRxiv (Cold Spring Harbor Laboratory) September 8, 2026 Tomokazu Tsurugizawa, Aya Takemura preprint

A single injection of a subanesthetic dose of ketamine, an NMDA receptor antagonist, induces schizophrenia-like behavior in mice. Previous studies investigated the effect of single injection of ketamine on behavior and c-Fos expression in mice dose-dependently. However, there has not been functional magnetic resonance imaging (fMRI) study to investigate the effect of ketamine in mice. Here, we...

EFFECTIVENESS OF MINDFULNESS-BASED STRESS REDUCTION TRAINING ON THE QUALITY OF NURSES' WORK LIFE

TMP Universal Journal of Research and Review Archives. September 8, 2026 Rana AsriZamani

Introduction: The present study aims to investigate the effectiveness of mindfulness-based stress reduction training on the quality of nurses' work life. Method: The present study is a quasi-experimental pre-test-post-test design with two groups (an experimental and a control group). The statistical population includes all nurses working at Tabriz International Hospital in 2022. For this...

Psychedelics and neuroregenerative medicine: Illuminating the potential of psychoplastogens for neurodevelopment and central nervous system repair

Psychedelics September 8, 2026 Hongyuan Li, Xiaohui Wang

Central nervous system (CNS) injuries remain challenging to treat due to limited neurogenesis, inhibitory extracellular environments, and maladaptive neuroimmune responses. Psychedelic compounds, including classical serotonergic psychedelics, dissociative anesthetics, and empathogens, have re-emerged as mechanistically distinctive “psychoplastogens” capable of rapidly and persistently enhancing...

Self and ego: a network view based on ecology and extended cognition.

Biosystems September 8, 2026 Emiliano Bruner

Frequently, the terms self and ego are employed as synonyms. From the one hand, this can obscure and confound different experiences related to consciousness. On the other hand, this can limit the use of these concepts when trying to express the human potential, and enhance well-being. Following the principles of ecology, system theory, and extended cognition, I propose an operational definition...

Correcting the lens changes the result: a proxy-fidelity audit framework for consciousness science

Zenodo (CERN European Organization for Nuclear Research) September 7, 2026 Flávio Marco Rego da Silva preprint

Consciousness science routinely operationalizes theoretical constructs — integration, complexity, coupling, level — as measurable proxies, and then tests hypotheses about the constructs through the proxies. This chain is only as strong as its weakest translation. We present a post-execution proxy-fidelity audit framework, developed and applied across 18 consecutive research cycles of a...

"Cannabis Green Wave" versus "Nicotine Freeze": the regulatory paradox of cannabis liberalization and nicotine prohibition.

Harm Reduction Journal September 7, 2026 Konstantinos Farsalinos

Background: The contemporary landscape of psychoactive substance regulation is characterized by a striking policy paradox. On one hand there is the gradual liberalization and mainstreaming of the cannabis market (the "Green Wave"), propelled by principles such as human rights, harm reduction, criminal justice reform, social equity, and economic efficiency. This coincides with a...
