A growing number of studies implicate functional brain networks in intelligence, but it is unclear if network nodal structure relates to intelligence. Using MRI, we studied the relationship of the general intelligence factor (g) with cortical thickness (CT), local gyrification index (LGI) and voxel-based morphometry in the nodes of the Default Mode Network (DMN) and Task-Positive Network (TPN)...

Abstract Default mode network (DMN) are the areas of the brain that get deactivated upon the presentation of externally focused, attention demanding tasks. Interestingly, these areas are consistently deactivated irrespective of the nature of the task. Recent evidence shows that the behavior of the DMN may be more nuanced than what was earlier believed. We wanted to investigate the dynamics of...

Abstract The default mode network (DMN) is a group of high-order brain regions recently implicated in processing external naturalistic events, yet it remains unclear what cognitive function it serves. Here we identified the cognitive states predictive of DMN fMRI coactivation. Particularly, we developed a state-fluctuation pattern analysis , matching network coactivations across a short movie...

Episodic memories showcase the complexity of internal thought: they bind together people, places, and events into coherent narratives, and they carry a subjective quality that sets them apart from other mental representations. In this review, I argue that episodic memory provides a powerful lens for understanding the functional organization of the default mode network (DMN). Recent research...

Abstract The default mode network (DMN), a set of transmodal cortical regions, has historically been argued to serve the internal functions of brain. The discovery of this network highlighted the brain’s intrinsic operations. The DMN generally decreases its activity during tasks and increases its activity during relaxed non-task states. It is important to investigate the nature of the DMN in...

One of the resting state networks is the default mode network (DMN); the DMN is primarily concerned with self-perception, orientation, and memory. Although EEG-DMN has been suggested to be active in the ultra-low frequency band below 1 Hz based on fMRI studies, the characteristics of the network have not yet been elucidated. In this study, we measured EEG-DMN during the eye-closed resting...

Patients undergoing Still Point induction via compression of the fourth ventricle (CV4) in cranial osteopathy commonly report a distinctive quality of profound mental quiet, described as qualitatively different from ordinary relaxation. Cranial osteopathy, however, entered a prolonged crisis of scientific credibility once controlled work indicated that its founding construct, the Primary...

Adolescent substance use is associated with increased risk of suicide, overdose, and executive dysfunction. Alcohol and marijuana are the two most-used substances among young people. Substance use is associated with dysfunctional resting-state network connectivity between the default mode network (DMN), executive control network (ECN), and salience network (SN) and executive dysfunction. There...

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...

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...
