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 ...

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.

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 segregation and social deficits in autism spectrum disorder: Evidence from non-medicated children

NeuroImage: Clinical, 2015
Functional pathology of the default mode network is posited to be central to social-cognitive impairment in autism spectrum disorders (ASD). Altered functional connectivity of the default mode network's midline core may be a potential endophenotype for ...

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.

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.

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 ...
