The default mode network in cognition: a topographical perspective

Nature Reviews Neuroscience, 2021
The default mode network (DMN) is a set of widely distributed brain regions in the parietal, temporal and frontal cortex. These regions often show reductions in activity during attention-demanding tasks but increase their activity across multiple forms of complex cognition, many of which are linked to memory or abstract thought.

The dynamic reorganization of the default-mode network during a visual classification task

Frontiers in Systems Neuroscience, 2013
The default-mode network has been reported to possess highly versatile and even contrasting functions but the underlying functioning mechanism remains elusive.

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

Dysmaturation of the default mode network in autism

Human Brain Mapping, 2013
Two hypotheses of autism spectrum disorder (ASD) propose that this condition is characterized by deficits in Theory of Mind and by hypoconnectivity between remote cortical regions with hyperconnectivity locally. The default mode network (DMN) is a set of remote, functionally connected cortical nodes less active during executive tasks than at rest and ...

Age differences in default mode activity on easy and difficult spatial judgment tasks

Frontiers in Human Neuroscience, 2010
The default network is a system of brain areas that are engaged when the mind is not involved in goal-directed activity. Most previous studies of age-related changes in default mode processing have used verbal tasks.

Reduced network integration in default mode and executive networks is associated with social and personal optimism biases [PDF]

, 2021
An optimism bias refers to the belief in good things happening to oneself in the future with a higher likelihood than is justified. Social optimism biases extend this concept to groups that one identifies with.

EEG PHASE RESET OF THE DEFAULT MODE NETWORK

Frontiers in Human Neuroscience, 2014
Objectives: The purpose of this study was to explore phase reset of 3-dimensional current sources located in Brodmann areas located in the human default mode network (DMN) using Low Resolution Electromagnetic Tomography (LORETA) of the human ...
