Cortical Function in Acute Severe Traumatic Brain Injury and at Recovery: A Longitudinal fMRI Case Study

Brain Sciences, 2020
Differences in the functional integrity of the brain from acute severe brain injury to subsequent recovery of consciousness have not been well documented.

Dynamic effective connectivity in resting state fMRI

NeuroImage, 2018
Context-sensitive and activity-dependent fluctuations in connectivity underlie functional integration in the brain and have been studied widely in terms of synaptic plasticity, learning and condition-specific (e.g., attentional) modulations of synaptic efficacy.

Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Functional Brain Asymmetry Reveals Heterogeneous Subtypes in Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Heterogeneity is a critical factor in understanding inter‐individual brain and behavioral variability in autism spectrum disorder (ASD). Since individuals with ASD exhibit atypical communication and social interaction skills closely linked to brain lateralization, this study investigated ASD heterogeneity using an asymmetry index that captures

Cortical Network Overconnectivity Relates to Sensory, Cognitive, and Social Dimensions in Young Children With Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT The heterogeneity in both the neurobiological mechanisms and the phenotypic presentations of autism spectrum disorder (ASD) poses a major challenge to clinical and translational research. Alterations in functional connectivity (FC) have been associated with ASD, yet it remains unclear whether and how divergent brain network properties may ...

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.

Individual‐specific resting‐state networks predict language dominance in drug‐resistant epilepsy

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to reliably estimate individual‐specific resting‐state cortical networks and determine whether language network topography can predict task‐based language dominance in drug‐resistant epilepsy. Methods We utilized a multisession hierarchical Bayesian model (MS‐HBM) trained on drug‐resistant epilepsy patients ...

The dynamic functional connectivity peak index: Detection of interictal epileptic activity with fMRI

Epilepsia, EarlyView.
Abstract Objective Epileptogenic zone (EZ) localization is crucial for surgical treatment of patients with medication‐resistant epilepsy. Although simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) can detect interictal discharges for EZ localization, clinical adoption is limited by the need for specialized ...

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.

Complementary predictive value of electromagnetic source imaging and hemodynamic responses in epilepsy surgery: A quantitative spatial analysis

Epilepsia, EarlyView.
Abstract Objective Accurate presurgical evaluation should assess not only the location but also the spatial extent of epileptic activity relative to the surgical cavity, a practical approximation of the epileptogenic zone. We evaluated how electromagnetic source imaging (EMSI) and hemodynamic responses to epileptic discharges relate to the surgical ...
