AbstractThis paper presents a model of consciousness grounded in hemispheric lateralization and theDefault Mode Network (DMN). Building on McGilchrist's Master/Emissary framework,Schore's developmental neuroscience, and Porges' polyvagal theory, it argues that the righthemisphere constitutes primary consciousness (Type 1) while the left hemisphere constructsthe narrative self (Type 2). The DMN...

Narrative comprehension involves creating a mental representation of the events of the story: a "situation model". Maintaining a situation model is thought to be supported by the Default Mode Network (DMN), but recent work suggests that the semantic system, and specifically the ventrolateral anterior temporal lobe (ATL), may play a role in reflecting on and restructuring the situation model via...

This record contains the full replication package for "Default Mode Network Geometry Emerges in Language Model Residual Streams From Next-Token Prediction on Agentive Text: A Universal Topological Signature Across 10 Architectures" (Alieksieienko, 2026). We report that the geometric topology of epistemic representations in transformer language model residual streams mirrors the functional...

AbstractWe present CORTEX, a biologically-inspired neural platform implementing two mechanisms derived from neuroscience that have not previously been demonstrated in artificial systems: (1) a Default Mode Network (DMN) that consolidates learned patterns through unsupervised internal replay during idle periods, and (2) a neurochemical adaptive router that reduces Large Language Model...

Everyday cognition depends on the brain's capacity to shift between sensing the external world and constructing it from memory. To achieve this, large-scale cortical systems must flexibly integrate incoming sensory signals with internally generated representations. Here, we show that this flexibility is reflected in the macroscale architecture of the default mode network (DMN). Using convergent...

BACKGROUND: In the postpartum period, postpartum women experience numerous brain structural and functional changes. Functional neuroimaging studies have focused on the responses of the maternal brain to infant stimuli ; however, the connectivity of the maternal brain remains to be explored. We aimed to examine the differences in functional connectivity patterns between postpartum women and...

Consciousness in Zen meditation has garnered considerable interest in psychology and neuroscience, particularly in relation to its association with enhanced self-awareness. Zen meditation fosters social harmony by addressing mental and social conflicts, linking individuals to various societal aspects through the practice. This meditation, rooted in Buddhism, aims to perceive thoughts without...

Abstract Increasing multiculturalism and globalization have increased the discrepancies between sociallyshared norms and personal values. This study investigated whether Cultural Estrangement (CE) and self-esteem (SE) interact to influence functional connectivity (FC) in the default mode network (DMN). In total, 170 healthy Japanese adults (18–70 years) were recruited, 70 of whom completed the...

Serotonin transporter gene polymorphism is important in the regulation of the serotoninergic system that affects mood and the regulation of emotions and behavior. In this study, 128 channel electroencephalogram recordings were performed, and buccal epithelium samples were obtained from 53 volunteers (32 females). La , Lg , and S alleles were identified by polymerase chain reaction. The aim of...

Mild cognitive impairment (MCI) is regarded a potential early stage of Alzheimer’s disease (AD) and associated with a significantly increased risk of progression to AD. This study aims to evaluate whole-brain static functional connectivity (SFC) disruptions with the default mode network (DMN) seed points in patients with MCI by resting-state functional magnetic resonance imaging (rs-fMRI), and...
