The impact of global signal regression on resting state correlations: Are anti-correlated networks introduced?

NeuroImage, 2008
Low-frequency fluctuations in fMRI signal have been used to map several consistent resting state networks in the brain. Using the posterior cingulate cortex as a seed region, functional connectivity analyses have found not only positive correlations in ...

Effectiveness of rTMS on Working Memory and Inhibitory Impairments in Patients With Post‐Stroke Executive Deficits

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

Motor priming induces changes in resting state dynamics in cerebellum of writer’s cramp dystonia: insights for clinical therapies

Dystonia
BackgroundWriter’s cramp (WC) is an adult-onset focal dystonia that impairs hand and arm movements during writing tasks. Previous studies have identified abnormal resting state connectivity between the basal ganglia and cerebellum in WC.

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Resting state networks characterization for individual subjects assessment [PDF]

, 2018
Cumulative research in hemodynamic brain activity measured in resting state (RS) using functional magnetic resonance imaging (fMRI) suggests that healthy brain dynamics are distributed on large-scale spatial resting state networks (RSNs). These networks

2010. Resting state networks change in clinically isolated syndrome [PDF]

, 2020
Task-functional magnetic resonance imaging studies have shown that early cortical recruitment exists in multiple sclerosis, which can partly explain the discrepancy between conventional magnetic resonance imaging and clinical disability. The study of the

Task-based functional connectivity in infants after exposure to regular white noise during natural sleep measured by fNIRS

Scientific Reports
The infant brain is primitive and immature. Investigating changes in the brain during infants’ rapid developmental stages has been a research hotspot. However, due to the unique characteristics of the infant population, maintaining an absolute resting ...

Altered network hub connectivity after acute LSD administration

NeuroImage: Clinical, 2018
LSD is an ambiguous substance, said to mimic psychosis and to improve mental health in people suffering from anxiety and depression. Little is known about the neuronal correlates of altered states of consciousness induced by this substance.

Linking functional connectivity and dynamic properties of resting-state networks

Scientific Reports, 2017
Spontaneous brain activity is organized into resting-state networks (RSNs) involved in internally-guided, higher-order mental functions (default mode, central executive and salience networks) and externally-driven, specialized sensory and motor ...
