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 ...

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 (

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 ...

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.

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

Role of the Default Mode Network in Cognitive Transitions [PDF]

Cerebral Cortex, 2018
ABSTRACTA frequently repeated finding is that the default mode network (DMN) shows activation decreases during externally-focused tasks. This finding has led to an emphasis in DMN research on internally-focused self-relevant thought processes. A recent study, in contrast, implicates the DMN in substantial externally-focused task switches.

Default mode network scaffolds immature frontoparietal network in cognitive development

Cerebral Cortex, 2022
The default mode network (DMN) is a workspace for convergence of internal and external information. The frontal parietal network (FPN) is indispensable to executive functioning.

Space wandering in the rodent default mode network

Proceedings of the National Academy of Sciences, 2023
The default mode network (DMN) is a large-scale brain network known to be suppressed during a wide range of cognitive tasks. However, our comprehension of its role in naturalistic and unconstrained behaviors has remained elusive because most research on the DMN has been conducted within the restrictive confines of MRI scanners.
