Transcranial stimulation of alpha oscillations up-regulates the default mode network

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance In the brain’s functional organization, the default mode network (DMN) represents a key architecture, whose dysregulation is involved in a host of major neuropsychiatric disorders.

A Pilot Study: Extraction of a Neural Network and Feature Extraction of Generation and Reduction Mechanisms Due to Acute Stress

Brain Sciences, 2023
This study aimed to compare the functional connectivity (FC) assessed during acute stress and recovery after stress using the Montreal imaging stress task (MIST) in adults in their 20s and 30s with Korean Perceived Stress Scale (PSS) scores between 15 ...

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

Microstructure of the Default Mode Network in Preterm Infants [PDF]

American Journal of Neuroradiology, 2016
Diffusion and fMRI has been providing insights to brain development in addition to anatomic imaging. This study aimed to evaluate the microstructure of white matter tracts underlying the default mode network in premature infants by using resting-state functional MR imaging in conjunction with diffusion tensor imaging-based tractography.A cohort of 44 ...

Imaging the default mode network in aging and dementia

Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2012
Although in the last decade brain activation in healthy aging and dementia was mainly studied using task-activation fMRI, there is increasing interest in task-induced decreases in brain activity, termed deactivations. These deactivations occur in the so-called default mode network (DMN).

Task-Related modulations of BOLD low-frequency fluctuations within the default mode Network [PDF]

, 2017
Spontaneous low-frequency Blood-Oxygenation Level-Dependent (BOLD) signals acquired during resting state are characterized by spatial patterns of synchronous fluctuations, ultimately leading to the identification of robust brain networks.

The Default Mode Network and the Problem of Determining Intrinsic Mental Contents

Studies in Logic, Grammar and Rhetoric, 2015
We provide a brief overview of the shift toward the intrinsic view of brain activity, describing in particular the structural and functional connectivity patterns of the “Default mode network” (part I).

Basal forebrain contributes to default mode network regulation [PDF]

, 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.
