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 ...

Gray space and default mode network-amygdala connectivity

Frontiers in Human Neuroscience, 2023
IntroductionAspects of the built environment relate to health factors and equity in living conditions, and may contribute to racial, ethnic, or economic health disparities.

The default mode network and cognition in Parkinson's disease: A multimodal resting‐state network approach

Human Brain Mapping, 2021
Involvement of the default mode network (DMN) in cognitive symptoms of Parkinson's disease (PD) has been reported by resting‐state functional MRI (rsfMRI) studies.

Deactivation of default mode network during touch [PDF]

Scientific Reports, 2019
AbstractInterpersonal touch possesses a strong affective component, which immediately evokes attention. The neural processing of such touch is moderated by specialized C-tactile nerve fibers in the periphery and results in central activation of somatosensory areas as well as regions involved in social processing, such as the superior temporal gyrus ...

Default-mode network activity distinguishes Alzheimer's disease from healthy aging: Evidence from functional MRI

Proc. Natl. Acad. Sci. USA, 2004
Recent functional imaging studies have revealed coactivation in a distributed network of cortical regions that characterizes the resting state, or default mode, of the human brain.

Dissociations between glucose metabolism and blood oxygenation in the human default mode network revealed by simultaneous PET-fMRI

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance A consistent finding from functional MRI (fMRI) of externally focused cognitive control is negative signal change in the brain’s default mode network (DMN), but it is unknown whether this reflects an increase of synaptic activity during rest

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.

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.
