Dynamic Brain Connectivity in Resting-State FMRI Using Spectral ICA and Graph Approach: Application to Healthy Controls and Multiple Sclerosis

open access: yesDiagnostics, 2022
Multiple sclerosis (MS) is a neuroinflammatory disease that involves structural and functional damage to the brain. It changes the functional connectivity of the brain between and within networks. Resting-state functional magnetic resonance imaging (fMRI)

Static and Dynamic Functional Connectivity Analysis of Cerebrovascular Reactivity: An fMRI Study [PDF]

open access: yesBrain and Behavior, 2019
ABSTRACT The human brain, as a finely-tuned system, needs a constant flow of oxygen to function properly. To accomplish this, the cerebrovascular system ensures a steady stream of oxygenation to brain cells. One tool that the cerebrovascular system uses is cerebrovascular reactivity (CVR), which is the system’s ...

Dynamic functional connectome predicts individual working memory performance across diagnostic categories

open access: yesNeuroImage: Clinical, 2021
Working memory impairment is a common feature of psychiatric disorders. Although its neural mechanisms have been extensively examined in healthy subjects or individuals with a certain clinical condition, studies investigating neural predictors of working

Static and Dynamic Connectivity Analysis of Human Brain via Functional Magnetic Resonance Imaging

open access: yes, 2022
Functional connectivity of brain refers to statistical dependence of brain functions among often remote neuronal units. This thesis addresses two novel ways to analyse brain functional connectivity.

From static to temporal network theory: Applications to functional brain connectivity [PDF]

open access: yesNetwork Neuroscience, 2016
Network neuroscience has become an established paradigm to tackle questions related to the functional and structural connectome of the brain. Recently, interest has been growing in examining the temporal dynamics of the brain’s network activity. Although different approaches to capturing fluctuations in brain connectivity have been proposed, there have

Social Dysfunction in ADHD Children Associated With Increased Amygdala Functional Connectivity Instability: A Static and Dynamic Functional Connectivity Study. [PDF]

open access: yesCNS Neurosci Ther
ABSTRACT Aims Social dysfunction (SD) is highly prevalent in children with attention‐deficit/hyperactivity disorder (ADHD), yet the underlying neural mechanisms remain poorly understood. The amygdala is a central hub for socio‐emotional processing, and altered functional connectivity (FC) may ...

Dynamic BOLD functional connectivity in humans and its electrophysiological correlates [PDF]

open access: yes, 2012
Neural oscillations subserve many human perceptual and cognitive operations. Accordingly, brain functional connectivity is not static in time, but fluctuates dynamically following the synchronization and desynchronization of neural populations.

Predictive signature of static and dynamic functional connectivity for ECT clinical outcomes

open access: yesFrontiers in Pharmacology, 2023
Introduction: Electroconvulsive therapy (ECT) remains one of the most effective approaches for treatment-resistant depressive episodes, despite the potential cognitive impairment associated with this treatment. As a potent stimulator of neuroplasticity, ECT might normalize aberrant depression-related brain function via the brain’s reconstruction by ...
