Research suggests that ADHD is characterized by dominant Default-Mode Network (DMN) and diminished Task Positive Network (TPN) activity, which has been linked to detrimentally affecting attention and executive task-dependent functioning. Interventions targeting this DMN-TPN interplay may be clinically important in ameliorating ADHD symptoms. This hypothesis was explored using frequency and...

Hemodialysis (HD) is the predominant treatment for end-stage renal disease (ESRD). Despite the efficacy of HD, the neurobiological underpinnings underlying high-risk complications remain unclear. In this study, using unsupervised fusion of functional and structural MRI, we identified a longitudinally altered default mode network (DMN)-insula pattern in ESRD receiving HD over 1-year follow-up (n...

The Default Mode Network was a key finding for cognitive neuroscience, but being the result of a data-driven analysis of resting-state fMRI data, its psychological and clinical implications have been difficult to elucidate. This is because in the resting-state paradigm we cannot directly correlate an observable specific task with specific brain connectivity patterns, and therefore inferences...

Humans spend considerable time contemplating the minds of others. But this ability is not limited to external agents-we also turn the lens for reading minds inward, reflecting on our own thoughts, emotions, and sense of self. Some processes involved in reasoning about minds may rely on shared mechanisms, while others may be specific to the agent under consideration. We developed a paradigm...

Psychedelic drugs are poised to become mainstream treatments, yet we lack a circuit-level account of how they reshape brain activity. Emerging evidence suggests that multiple psychedelic compounds modulate activity in the brain's default mode network (DMN), often interpreted as either increased or decreased bottom-up hierarchical processing. Most imaging studies, however, quantify activity as...

Abstract In recent decades, the psychedelic psilocybin has been studied as a potential treatment for major depressive disorder (MDD), offering an alternative to traditional antidepressants. However, the brain changes underlying the clinical effects of different interventions remain unclear. Here, we investigated the effects of psilocybin and a conventional antidepressant, escitalopram, from the...

We examine the claim that a minimal-conceptual, “bare” awareness underlies ordinary experience, and whether this pre-conceptual awareness (PCA, or minimal-dual awareness) should be understood primarily as an earlier, biologically rooted developmental baseline, or as a disclosure of a deeper ontological reality. The Retrieval hypothesis treats PCA as a cognitive–neural default mode that can be...

Abstract Psilocybin and other serotonergic psychedelics show therapeutic promise for psychiatric disorders, yet objective neural correlates linking the acute psychedelic state to persisting psychological outcomes remain limited. Electroencephalography (EEG) microstate analysis characterizes the rapid spatiotemporal organization of large-scale brain activity, offering a millisecond-resolution...

Little is known about the neurocognitive underpinnings of forming social connections. In this study, we tested whether default mode network (DMN) inter-brain synchrony (which prior work has linked to interpersonal alignment, or 'seeing eye-to-eye') predicts feelings of connection during conversations. Seventy pairs of strangers engaged in shallow or deep conversations while brain activity was...

Introduction: Affective disorders (ADs) are characterized by profound emotional processing deficits involving disrupted neural network activity and connectivity, particularly within the default mode network and fronto-temporal circuits, with abnormalities in theta and alpha oscillatory patterns. While current treatments primarily target mood symptoms, emotional processing impairments often...

Functional neuroimaging studies consistently show that episodic recollection engages the default mode network (DMN), yet the extent to which this engagement varies with the representational content of retrieved information remains unclear. The present meta-analysis examined whether recollection of verbal and visual materials differentially recruits the DMN. Twenty-four verbal and 19 visual...

The default mode network (DMN) has been central to cognitive neuroscience research for over two decades, yet understanding of its contribution to decision-making remains incomplete. This review synthesizes recent evidence demonstrating that the DMN directly supports subjective valuation and value-based decision-making. Anatomically and functionally, core DMN regions-including the ventromedial...

When Freud invented/discovered psychoanalysis, he devised not just a theory of mind but also a tool that enabled him to observe the "mind." And with the tool of psychoanalysis, he was able to observe the workings of the default mode network (DMN) some hundred years before anyone knew of its existence. Since then, various operations of the DMN have been identified. One is the integration of...

Spontaneous pupil fluctuations (SPFs) during rest provide a non-invasive, low-cost index of central arousal dynamics, independent of cognitive task demands. These features position SPFs as promising markers for baseline neurophysiological activity in both basic and translational research. This review synthesizes current evidence on the resting-state pupil-brain system, focusing on its core...
