Altered Dynamic Functional Network Connectivity in Post‐Stroke Aphasia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Previous studies examining post‐stroke aphasia (PSA) patients via resting‐state functional magnetic resonance imaging (rs‐fMRI) have predominantly focused on static functional connectivity. In contrast, the current investigation aims to elucidate the alterations in dynamic functional network connectivity (dFNC) among PSA patients ...

Magnetorotational Instability in Core-Collapse Supernovae

, 2017
We discuss the relevance of the magnetorotational instability (MRI) in core-collapse supernovae (CCSNe). Our recent numerical studies show that in CCSNe, the MRI is terminated by parasitic instabilities of the Kelvin-Helmholtz type.

Analysis of white matter tract integrity using diffusion kurtosis imaging reveals the correlation of white matter microstructural abnormalities with cognitive impairment in type 2 diabetes mellitus

Frontiers in Endocrinology
BackgroundThis study aimed to identify disruptions in white matter integrity in type 2 diabetes mellitus (T2DM) patients by utilizing the white matter tract integrity (WMTI) model, which describes compartment-specific diffusivities in the intra- and ...

Prevalence of Stroke and Diagnostic Performance of Emergency MRI in Acute Isolated Dizziness

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Stroke is frequently misdiagnosed in patients presenting with acute isolated dizziness; the optimal imaging modality for this population remains debated. This study aimed to determine the prevalence of stroke among patients with isolated dizziness and to assess the diagnostic accuracy of magnetic resonance imaging (MRI) and computed ...

Brain activity during traditional textbook and audiovisual‐3D learning

Brain and Behavior, 2019
Introduction Audiovisual educational tools have increasingly been used during the past years to complement and compete with traditional textbooks. However, little is known as to how the brain processes didactic information presented in different formats.

The Diverse Neuromuscular Spectrum of VPS13A Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective VPS13A disease (chorea‐acanthocytosis) is a rare neurodegenerative disorder caused by biallelic variants in VPS13A, typically presenting with hyperkinetic movement disorders, while neuromuscular signs are often mild. The aim of the project was to investigate the frequency and severity of neuromuscular impairment in VPS13A disease ...

Glymphatic MRI in idiopathic normal pressure hydrocephalus

Brain : a journal of neurology, 2017
The glymphatic system has been shown in animal studies to support the clearance of waste metabolites from the brain interstitial space. Using MRI, Ringstad et al. visualize the glymphatic system for the first time in humans. Glymphatic clearance is sleep-

Naming fMRI predicts the effect of temporal lobe resection on language decline

Annals of Clinical and Translational Neurology, 2019
Objective To develop language functional MRI (fMRI) methods that accurately predict postsurgical naming decline in temporal lobe epilepsy (TLE). Methods Forty‐six patients with TLE (25 left) and 19 controls underwent two overt fMRI paradigms (auditory ...

Lesion Location and Functional Connections Reveal Cognitive Impairment Networks in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive impairment, fatigue, and depression are common in multiple sclerosis (MS), potentially due to disruption of regional functional connectivity caused by white matter (WM) lesions. We explored whether WM lesions functionally connected to specific brain regions contribute to these MS‐related manifestations.
