Gamification of learning deactivates the Default Mode Network [PDF]

Frontiers in Psychology, 2016
We hypothesised that embedding educational learning in a game would improve learning outcomes, with increased engagement and recruitment of cognitive resources evidenced by increased activation of working memory network (WMN) and deactivation of Default ...

Brain default-mode network dysfunction in addiction

NeuroImage, 2019
Aberrant patterns of brain functional connectivity in the default mode network (DMN) have been observed across different classes of substance use disorder (SUD) and are associated with craving and relapse.

The Default Mode Network and Altered Consciousness in Epilepsy [PDF]

Behavioural Neurology, 2011
The default mode network has been hypothesized based on the observation that specific regions of the brain are consistently activated during the resting state and deactivated during engagement with task. The primary nodes of this network, which typically

The default mode network’s role in discrete emotion

Trends in Cognitive Sciences, 2019
Emotions are often assumed to manifest in subcortical limbic and brainstem structures. While these areas are clearly important for representing affect (e.g.

The Default Mode Network in Autism [PDF]

Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, 2017
Autism spectrum disorder (ASD) is characterized by deficits in social communication and interaction. Since its discovery as a major functional brain system, the default mode network (DMN) has been implicated in a number of psychiatric disorders, including ASD.

Amyloid induced hyperexcitability in default mode network drives medial temporal hyperactivity and early tau accumulation

Neuron, 2023
Summary: In early Alzheimer’s disease (AD) β-Amyloid (Aβ) deposits throughout association cortex and tau appears in the entorhinal cortex (EC). Why these initially appear in disparate locations is not understood.

Optogenetic stimulation of anterior insular cortex neurons in male rats reveals causal mechanisms underlying suppression of the default mode network by the salience network

Nature Communications, 2023
The salience network has been hypothesised to modulate default mode network activity during stimulus-driven cognition. Here, the authors show that in rats, stimulation of the anterior insular cortex, a key node of the salience network, suppresses the ...

The default mode network and rumination in individuals at risk for depression

Social Cognitive and Affective Neuroscience, 2023
The default mode network (DMN) is a network of brain regions active during rest and self-referential thinking. Individuals with major depressive disorder (MDD) show increased or decreased DMN activity relative to controls. DMN activity has been linked to

Effects of integrated hospital treatment on the default mode, salience, and frontal-parietal networks in anorexia nervosa: A longitudinal resting-state functional magnetic resonance imaging study.

PLoS ONE, 2023
The psychopathology of patients with anorexia nervosa has been hypothesized to involve inappropriate self-referential processing, disturbed interoceptive awareness, and excessive cognitive control, including distorted self-concern, disregard of their own

Dose-related adaptive reconstruction of DMN in isoflurane administration: a study in the rat

BMC Anesthesiology, 2023
Background The anesthetic states are accompanied by functional alterations. However, the dose-related adaptive alterations in the higher-order network under anesthesia, e. g. default mode network (DMN), are poorly revealed.
