Dynamic models of brain imaging data and their Bayesian inversion [PDF]

, 2010
This work is about understanding the dynamics of neuronal systems, in particular with respect to brain connectivity. It addresses complex neuronal systems by looking at neuronal interactions and their causal relations.

Caffeine alters resting- state functional connectivity measured by blood oxygenation level- dependent MRI

, 2017
This study aimed to investigate the pharmacological effect of caffeine on functional connectivity measured by resting-state blood oxygenation level-dependent (BOLD) MRI in the motor cortex, visual cortex and default mode network (DMN).

Abnormal dynamic functional connectivity in young nondisabling intracerebral hemorrhage patients

Annals of Clinical and Translational Neurology
Objective Previous resting‐state functional magnetic resonance imaging studies on intracerebral hemorrhage patients have focused more on the static characteristics of brain activity, while the time‐varying effects during scanning have received less ...

Dynamics of Intersubject Brain Networks during Anxious Anticipation

Frontiers in Human Neuroscience, 2017
How do large-scale brain networks reorganize during the waxing and waning of anxious anticipation? Here, threat was dynamically modulated during human functional MRI as two circles slowly meandered on the screen; if they touched, an unpleasant shock was ...

Functional brain network reconfiguration during learning in a dynamic environment

Nature Communications, 2020
Adaptive adjustments in learning dynamics are accompanied by dynamic changes in a pattern of whole-brain functional connectivity characterized by integration between fronto-parietal and other networks.

Comparing the Effect of Semi‐Immersive Virtual Reality, Computerized Cognitive Training, and Traditional Rehabilitation on Cognitive Function in Multiple Sclerosis: A Randomized Clinical Trial

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Cognitive impairment is a common non‐motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi‐immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR ...

Neonatal brain dynamic functional connectivity in term and preterm infants and its association with early childhood neurodevelopment

Nature Communications
Brain dynamic functional connectivity characterises transient connections between brain regions. Features of brain dynamics have been linked to emotion and cognition in adult individuals, and atypical patterns have been associated with neurodevelopmental

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 ...

Individual differences in white matter microstructure reflect variation in functional connectivity during action choice. [PDF]

, 2007
The relation between brain structure and function is of fundamental importance in neuroscience. Comparisons between behavioral and brain imaging measures suggest that variation in brain structure correlates with the presence of specific skills[1-3 ...
