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.

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

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 (

Default Mode Network Modulation by Psychedelics: A Systematic Review

International Journal of Neuropsychopharmacology, 2022
Psychedelics are a unique class of drug that commonly produce vivid hallucinations as well as profound psychological and mystical experiences. A grouping of interconnected brain regions characterized by increased temporal coherence at rest have been ...

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

The subcortical default mode network and Alzheimer’s disease: a systematic review and meta-analysis

medRxiv, 2023
The default mode network is a central cortical brain network suggested to play a major role in several disorders, and to be particularly vulnerable to the neuropathological hallmarks of Alzheimers disease.

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.

Aberrant Correlation Between the Default Mode and Salience Networks in Mild Traumatic Brain Injury

Frontiers in Computational Neuroscience, 2020
Objectives: The specific intrinsic network coupling abnormalities in mild traumatic brain injury (mTBI) patients are poorly understood. Our objective is to compare the correlations among the default mode, salience, and central executive networks in ...

Chemogenetic stimulation of tonic locus coeruleus activity strengthens the default mode network

Science Advances, 2022
The default mode network (DMN) of the brain is functionally associated with a wide range of behaviors. In this study, we used functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and spectral fiber photometry to investigate ...
