Aerobic training modulates salience network and default mode network metabolism in subjects with mild cognitive impairment

NeuroImage: Clinical, 2018
Aerobic training (AT) is a promising intervention to improve cognitive functioning. However, its modulatory effects on brain networks are not yet entirely understood.

Default Mode Network Maturation and Environmental Adversities During Childhood

Chronic Stress, 2018
Default mode network (DMN) plays a central role in cognition and brain disorders. It has been shown that adverse environmental conditions impact neurodevelopment, but how these conditions impact in DMN maturation is still poorly understood.

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

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.

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 ...

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.

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.
