Altered Inter-Network Functional Integration Underlies Speech Impairment in Parkinson's Disease: A Resting-State fMRI Analysis. [PDF]

Brain Behav
Resting‐state functional magnetic resonance imaging and independent component analysis were used to compare large‐scale functional network connectivity among patients with Parkinson's disease with speech disorders (PD‐SD, n = 62), patients without speech disorders (PD‐NON‐SD, n = 16), and healthy controls (HC, n = 36).

Cognitive Dysfunction in Chronic Rhinosinusitis: A Scoping Review

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Cognitive dysfunction is increasingly recognized as an extra‐nasal manifestation of chronic rhinosinusitis (CRS). This scoping review characterizes the primary evidence on cognition in adult CRS, covering measures, treatment response, and incident dementia.

Correspondence Between Resting-State and Episodic Memory-Task Related Networks in Elderly Subjects

Frontiers in Aging Neuroscience, 2018
Resting-state fMRI studies demonstrated temporally synchronous fluctuations in brain activity among ensembles of brain regions, suggesting the existence of intrinsic functional networks.

Atypical Cerebellar Responses are Associated with Altered Neural Habituation during Sensory Stimulation in Autism

Autism Research, EarlyView.
ABSTRACT Sensory processing atypicalities are highly prevalent in autistic youth; yet, the neural mechanisms underlying these differences are not well understood. While the cerebellum plays a key role in sensorimotor coordination and is structurally and functionally atypical in the autistic brain, it has been overlooked in research investigating ...

Shifted Coupling of EEG Driving Frequencies and fMRI Resting State Networks in Schizophrenia Spectrum Disorders [PDF]

, 2013
INTRODUCTION: The cerebral resting state in schizophrenia is altered, as has been demonstrated separately by electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) resting state networks (RSNs).

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

Epileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.

Ten Key Insights into the Use of Spinal Cord fMRI

Brain Sciences, 2018
A comprehensive review of the literature-to-date on functional magnetic resonance imaging (fMRI) of the spinal cord is presented. Spinal fMRI has been shown, over more than two decades of work, to be a reliable tool for detecting neural activity.

Ventral anterior thalamic dysfunction distinguishes seizure generalization in temporal lobe epilepsy

Epilepsia, EarlyView.
Abstract Objective Focal‐to‐bilateral tonic–clonic seizures (FBTCS) in temporal lobe epilepsy (TLE) involve thalamocortical networks, yet the functional integrity and role of specific thalamic subregions in seizure generalization remain unclear. In this cross‐sectional study, we investigated whether thalamic subregion functional connectivity patterns ...

Detecting spatiotemporal nonlinear dynamics in resting state of human brain based on fMRI datasets

, 2008
In this work, a nonlinear dynamics method, coupled map lattices, was applied to functional magnetic resonance imaging (fMRI) datasets to examine the spatiotemporal properties of resting state blood oxygen level-dependent (BOLD) fluctuations ...

Neurovascular coupling in eye-open-eye-close task and resting state: Spectral correspondence between concurrent EEG and fMRI

NeuroImage
Neurovascular coupling serves as an essential neurophysiological mechanism in functional neuroimaging, which is generally presumed to be robust and invariant across different physiological states, encompassing both task engagement and resting state ...
