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

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

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.

Default mode network in the effects of Δ9-Tetrahydrocannabinol (THC) on human executive function. [PDF]

PLoS ONE, 2013
Evidence is increasing for involvement of the endocannabinoid system in cognitive functions including attention and executive function, as well as in psychiatric disorders characterized by cognitive deficits, such as schizophrenia.

The default mode network is affected in the early stage of simian immunodeficiency virus infection: a longitudinal study

Neural Regeneration Research, 2023
Acquired immune deficiency syndrome infection can lead to cognitive dysfunction represented by changes in the default mode network. Most recent studies have been cross-sectional and thus have not revealed dynamic changes in the default mode network ...

Intrinsic brain dynamics in the Default Mode Network predict involuntary fluctuations of visual awareness

Nature Communications, 2022
The default mode network (DMN) is known to be involved in consciousness. Here the authors show intrinsic EEG oscillations in default mode network can predict upcoming involuntarily perceptual transitions.

Abnormal Large-Scale Neuronal Network in High Myopia

Frontiers in Human Neuroscience, 2022
AimResting state functional magnetic resonance imaging (rs-fMRI) was used to analyze changes in functional connectivity (FC) within various brain networks and functional network connectivity (FNC) among various brain regions in patients with high myopia (

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 ...

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.
