The Brain as a Low-Resistance Pathway Network: A Cross-Domain Evidence Synthesis from White Matter Microstructure, Sleep Deprivation, and Default Mode Network Metabolism

Zenodo (CERN European Organization for Nuclear Research) July 20, 2026 Menggang Yu

The core physical attributes of the brain—the lifelong decline of white matter microstructural integrity, the selective cognitive impairment caused by sleep deprivation, and the high resting-state energy consumption of the default mode network—are currently dispersed across independent domains of neuroimaging, sleep science, and cognitive neuroscience. This paper proposes that these phenomena...

Source-level α periodic power in visual and default mode networks predicts topiramate treatment response in migraine

The Journal of Headache and Pain July 17, 2026 Siyuan Xie, Chenghui Pi, Kang Jin et al.

BACKGROUND: Migraine is highly heterogeneous, and patients exhibit substantial variability in their responses to preventive treatment. The dose-escalation strategy of topiramate further complicates early evaluation of therapeutic efficacy. Identifying neurobiological markers that can predict treatment response is therefore essential for individualized therapy. In this study, we constructed...

Sensory Saturation and Cognitive Surrender: A Theoretical Framework for Altered Perceptual States in Immersive Neurogastronomic Dining

PsyArXiv Preprints July 16, 2026

This paper proposes a theoretical framework for interpreting immersive neurogastronomic experiences as a form of ambient cognitive modulation. The framework originates in the direct, informal observation of approximately 6,000 guests conducted by the first author over more than six years of operation at Sensorium — an eleven-seat neurogastronomic restaurant with a controlled multisensory...

JAK-STAT pathway inhibition modulates centrally sensitised default mode network hubs in rheumatoid arthritis pain

medRxiv July 14, 2026 Kristian Stefanov, Joel T. Parkinson, Flavia Sunzini et al.

Abstract Nociplastic pain represents a major burden across immune-mediated inflammatory diseases (IMIDs). It is hypothesised, but not yet demonstrated, that peripheral inflammation promotes nociplastic pain by bottom-up sensitisation of the central nervous system (CNS). In rheumatoid arthritis (RA), a prototypic IMID, we used ultra–high field (7T) brain resting-state functional MRI to evaluate...

Mahamrityunjaya: The Mantra That Answers What Evolution Created — The Prefrontal Cortex and the Human Fear of Death

Zenodo (CERN European Organization for Nuclear Research) July 14, 2026 Narayan Rout

This article proposes and develops an original interdisciplinary thesis: the Mahamrityunjaya Mantra of the Rigveda (7.59.12) is the Indian civilisation's systematic response to the specific psychological wound created by the evolution of the prefrontal cortex. The article develops this thesis through seven dimensions: the evolutionary emergence of the PFC (bipedalism, cooking, social...

Neural Information Systems Theory: First-Order Thalamic Downsampling Instability and Second-Order Default Mode Network Integration Cascading Failure Hypothesis

Zenodo (CERN European Organization for Nuclear Research) July 12, 2026 Yue Lu

Abstract— This paper introduces a novel neuroinformatics framework rooted in Status-Relational Entropy (SRE) dynamics to deconstruct the multi-tier gating mechanisms of the human brain from a cybernetics and digital signal processing (DSP) perspective. We model the brain as a distributed, multi-tier stepped dynamic defense system managing massive environmental data throughput. The primary gate...

Dopamine Compensates for Amyloid-Induced Default Mode Network Dysfunction to Support Learning

bioRxiv (Cold Spring Harbor Laboratory) July 10, 2026 Joseph Giorgio, Thomas Morin, Hsiang-Yu Chen et al.

Throughout the preclinical phase of Alzheimer's disease (AD) β-amyloid (Aβ) accumulates preferentially within the default mode network (DMN), yet the functional and behavioural consequences of this pathological burden remain poorly understood. Using task-based fMRI combined with Aβ, tau, and dopamine PET in cognitively normal older adults, we show that Aβ burden impairs learning independent of...

Neural Correlates of Cognitive Alterations and Minor and Structured Hallucinations in Parkinson's Disease

medRxiv July 10, 2026 Lada Kohoutová, Jevita Potheegadoo, Léa F Duong Phan Thanh et al.

Background: Hallucinations, ranging from minor (MH) to structured, are a common non-motor symptom in Parkinson's disease (PD). Structured hallucinations have been associated with altered functional connectivity (FC) between dorsal/ventral attention (DAN, VAN) and default mode (DMN) networks. As structured hallucinations are linked to rapid cognitive decline and MH are often viewed as their...

Multilayer brain network analysis in mice reveals ketamine-induced reorganization of brain- wide fluctuations and gut-brain axis

Communications Biology July 3, 2026 Fengkai He, Xiaojun Xu, Y Y Zhu et al.

Depression involves dysregulation across distributed cortico-limbic circuits, and ketamine is notable for its rapid antidepressant effects. Although depression and ketamine treatment have been linked to altered brain network topology, how within-frequency and cross-frequency coupling are jointly reorganized at the brain-wide level remains unclear. Here, we developed a frequency-varying...

Nondual mindfulness meditation alters self representation and brain connectome in expert meditators

bioRxiv (Cold Spring Harbor Laboratory) July 3, 2026 Sébastien Czajko, Jelle Zorn, Oussama Abdoun et al.

Nonduality is a foundational but conceptually elusive notion across several contemplative traditions. Nondual traditions challenge the assumption that a subject-object structure characteristic of ordinary experience is an intrinsic feature of conscious awareness. However, little remains known about the neurocognitive mechanisms associated with such experiential state. Here, we investigated how...

The DMN between Imagination, Creativity and Musement: a new path for neurosemiotics

Linguistic Frontiers July 1, 2026 Luigi Lobaccaro

Abstract: The Default Mode Network (DMN) is reshaping cognitive neuroscience, offering fresh insights into high-level cognitive processes and the relationship between the humanities and the natural sciences. This article explores how neuroscientific research on the DMN can inform a neurosemiotic approach. It builds on Duarte’s recent proposal (2020; 2022) to associate the activities of this...

Astrocytic Calcium and Default Mode Network Dysfunction in Early Stage AD

Alzheimer's Disease - Diagnostics, Pathogenesis, and Treatment [Working Title] July 1, 2026 Denis Larrivee

While most theories regarding Alzheimer’s disease (AD) pathogenesis adopt a “neurocentric” perspective, increasing evidence suggests that nonneuronal cells may be a primary site of pathogenesis in early stage AD. Several years prior to the appearance of amyloid plaques and neurofibrillary tangles (NFTs), functional connectivity (FC) changes can be observed in the human cingulate cortex, a...

Default mode network hub disruption links problematic use of the Internet to brain network disorganization.

Comprehensive Psychiatry July 1, 2026 Nagara Takao, Naoya Oishi, Qi Dai et al.

Problematic Use of the Internet (PUI) has been associated with functional alterations in the default mode network (DMN), which contains critical hubs in the entire brain network. Previous studies have predicted that hub disruption leads to widespread network alterations; however, whether DMN functional connectivity mediates the relationship between PUI and global network topology remains...

Distinct frontal lobe subregions mediate the emergence and reporting of visual consciousness.

Neuroimage July 1, 2026 Yan Zhang, Xiarong Li, Zhenlan Jin et al.

Persistent debate surrounds whether the frontal lobe supports the emergence or reporting of consciousness, raising the hypothesis that distinct frontal subregions may support these processes. We addressed this by combining electroencephalography (EEG) with eye-tracking in Report and No-Report paradigms. Eye-movement features distinguished conscious and unconscious trials in the no-report task....
