The Resolution Matrix for Visualizing Functional Network Connectivity

CoRR, 2020
The resolution matrix is a mathematical tool for analyzing inverse problems such as computational imaging systems. When treating network connectivity estimation as an inverse problem, the resolution matrix describes the degree to which network nodes and edges can be resolved.

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 ...

Aberrant Dynamic Functional Network Connectivity and Graph Properties in Major Depressive Disorder

Frontiers in Psychiatry, 2018
Major depressive disorder (MDD) is a complex mood disorder characterized by persistent and overwhelming depression. Previous studies have identified abnormalities in large scale functional brain networks in MDD, yet most of them were based on static ...

Functional specialization and network connectivity in brain function

, 2016
Do mental processes depend from ‘localized’ brain regions or are they ‘global’ resulting from the integrated functioning of the brain as a whole? Brain lesion studies and neuroimaging methods have given evidence of both interpretations, allowing contemporary neuroscience to reach the conclusion that localized regions of the brain do carry out specific ...

Network Structure Shapes Spontaneous Functional Connectivity Dynamics [PDF]

The Journal of Neuroscience, 2015
The structural organization of the brain constrains the range of interactions between different regions and shapes ongoing information processing. Therefore, it is expected that large-scale dynamic functional connectivity (FC) patterns, a surrogate measure of coordination between brain regions, will be closely tied to the fiber pathways that form the ...

White Matter Hyperintensity Burden and Short‐Interval Change Associated With Sleep Apnoea in the UK Biobank

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined. We

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 ...

Anti‐CD19 CAR T Cells in Autoimmune Encephalitis: Inflammation Controlled, Neurodegeneration Unchecked?

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Just recently, successful chimeric antigen receptor (CAR) T cell therapy was reported in the first patient with refractory, anti‐diacylglycerol lipase alpha (DAGLA) antibody‐mediated autoimmune encephalitis, achieving partial clinical remission.

Dynamic functional network connectivity in Huntington's disease and its associations with motor and cognitive measures

Human Brain Mapping, 2019
Dynamic functional network connectivity (dFNC) is an expansion of traditional, static FNC that measures connectivity variation among brain networks throughout scan duration. We used a large resting‐state fMRI (rs‐fMRI) sample from the PREDICT‐HD study (N

Meal replacement and functional connectivity in the brain network for appetite: connecting the dots [PDF]

Frontiers in Psychology, 2015
The article by Paolini and colleagues is a part of the Research Topic “The two-way link between eating behavior and brain metabolism” (Zilberter, 2015). The authors were first to report the effect of MR on brain networks during moderate hunger state. They used sophisticated analytical/experimental techniques and observed a new phenomenon, which they ...
