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 ...

The default mode network in cognition: a topographical perspective

Nature Reviews Neuroscience, 2021
The default mode network (DMN) is a set of widely distributed brain regions in the parietal, temporal and frontal cortex. These regions often show reductions in activity during attention-demanding tasks but increase their activity across multiple forms of complex cognition, many of which are linked to memory or abstract thought.

Default Mode Network Connectivity in Stroke Patients. [PDF]

PLoS ONE, 2013
The pathophysiology of episodic memory dysfunction after infarction is not completely understood. It has been suggested that infarctions located anywhere in the brain can induce widespread effects causing disruption of functional networks of the cortical

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 ...

Disruption to control network function correlates with altered dynamic connectivity in the wider autism spectrum [PDF]

NeuroImage: Clinical, 2017
Autism is a common developmental condition with a wide, variable range of co-occurring neuropsychiatric symptoms. Contrasting with most extant studies, we explored whole-brain functional organization at multiple levels simultaneously in a large subject ...

Recruitment of the default mode network during a demanding act of executive control [PDF]

eLife, 2015
In the human brain, a default mode or task-negative network shows reduced activity during many cognitive tasks and is often associated with internally-directed processes, such as mind wandering and thoughts about the self.

Default mode network activity in depression subtypes

Reviews in the Neurosciences, 2021
Depression continues to carry a major disease burden worldwide, with limitations on the success of traditional pharmacological or psychological treatments. Recent approaches have therefore focused upon the neurobiological underpinnings of depression, and

Basal forebrain contributes to default mode network regulation [PDF]

Proceedings of the National Academy of Sciences, 2018
The default mode network (DMN) is a collection of cortical brain regions that is active during states of rest or quiet wakefulness in humans and other mammalian species.

Default-mode-like network activation in awake rodents. [PDF]

PLoS ONE, 2011
During wakefulness and in absence of performing tasks or sensory processing, the default-mode network (DMN), an intrinsic central nervous system (CNS) network, is in an active state. Non-human primate and human CNS imaging studies have identified the DMN

Examining recent effects of caffeine on default mode network and dorsal attention network anticorrelation in youth. [PDF]

PLoS ONE
ObjectivesIn adolescence, caffeinated beverage consumption is negatively associated with cognitive functioning. The default mode network and dorsal attention network are anticorrelated brain systems that are essentially implicated in attention.
