Damage to the Salience Network and Interactions with the Default Mode Network [PDF]

Journal of Neuroscience, 2014
Interactions between the Salience Network (SN) and the Default Mode Network (DMN) are thought to be important for cognitive control. However, evidence for a causal relationship between the networks is limited. Previously, we have reported that traumatic damage to white matter tracts within the SN predicts abnormal DMN function.

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 ...

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.

Functional connectivity in the resting brain: A network analysis of the default mode hypothesis

Proceedings of the National Academy of Sciences of the United States of America, 2002
Functional imaging studies have shown that certain brain regions, including posterior cingulate cortex (PCC) and ventral anterior cingulate cortex (vACC), consistently show greater activity during resting states than during cognitive tasks.

Viewing personalized video clips recommended by TikTok activates default mode network and ventral tegmental area

NeuroImage, 2021
Cutting-edge recommendation algorithms have been widely used by media platforms to suggest users with personalized content. While such user-specific recommendations may satisfy users' needs to obtain intended information, some users may develop a ...

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

Cerebral Cortex, 2018
ABSTRACT A 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 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 ...

Tasks activating the default mode network map multiple functional systems

Brain Structure and Function, 2022
Recent developments in network neuroscience suggest reconsidering what we thought we knew about the default mode network (DMN). Although this network has always been seen as unitary and associated with the resting state, a new deconstructive line of ...

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
