Refugee visa insecurity disrupts the brain’s default mode network

European Journal of Psychotraumatology, 2023
Background: Research has largely focused on the psychological consequences of refugee trauma exposure, but refugees living with visa insecurity face an uncertain future that also adversely affects psychological functioning and self-determination ...

Individual differences in delay discounting are associated with dorsal prefrontal cortex connectivity in children, adolescents, and adults

Developmental Cognitive Neuroscience, 2023
Delay discounting is a measure of impulsive choice relevant in adolescence as it predicts many real-life outcomes, including obesity and academic achievement.

Fluctuations between high- and low-modularity topology in time-resolved functional connectivity [PDF]

, 2017
Modularity is an important topological attribute for functional brain networks. Recent studies have reported that modularity of functional networks varies not only across individuals being related to demographics and cognitive performance, but also ...

Affective modulation of cognitive control is determined by performance-contingency and mediated by ventromedial prefrontal and cingulate cortex [PDF]

, 2013
Cognitive control requires a fine balance between stability, the protection of an on-going task-set, and flexibility, the ability to update a task-set in line with changing contingencies.

The default mode network and the working memory network are not anti-correlated during all phases of a working memory task.

PLoS ONE, 2015
IntroductionThe default mode network and the working memory network are known to be anti-correlated during sustained cognitive processing, in a load-dependent manner.

Parcellation‐based anatomic modeling of the default mode network

Brain and Behavior, 2021
Background The default mode network (DMN) is an important mediator of passive states of mind. Multiple cortical areas, such as the anterior cingulate cortex, posterior cingulate cortex, and lateral parietal lobe, have been linked in this processing ...

Psychopathic traits and altered resting-state functional connectivity in incarcerated adolescent girls

Frontiers in Neuroimaging, 2023
Previous work in incarcerated boys and adult men and women suggest that individuals scoring high on psychopathic traits show altered resting-state limbic/paralimbic, and default mode functional network properties.

Default mode network electrophysiological dynamics and causal role in creative thinking

Brain : a journal of neurology
The default mode network (DMN) is a widely distributed, intrinsic brain network thought to play a crucial role in internally directed cognition. The present study employs stereo-EEG in 13 human patients, obtaining high resolution neural recordings across

Changes in Default-Mode Network Associated With Childhood Trauma in Schizophrenia

Schizophrenia bulletin, 2021
Background There is considerable evidence of dysconnectivity within the default-mode network (DMN) in schizophrenia, as measured during resting-state functional MRI (rs-fMRI).

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).
