Functional connectivity of human striatum: a resting state FMRI study.

Cerebral Cortex, 2008
Classically regarded as motor structures, the basal ganglia subserve a wide range of functions, including motor, cognitive, motivational, and emotional processes.

Resting-state fMRI as a biomarker for Alzheimer's disease? [PDF]

Alzheimer's Research & Therapy, 2012
Previous work indicates that resting-state functional magnetic resonance imaging (fMRI) is sensitive to functional brain changes related to Alzheimer's disease (AD) pathology across the clinical spectrum. Cross-sectional studies have found functional connectivity differences in the brain's default mode network in aging, mild cognitive impairment, and ...

Increased Serum Neurofilament Light Chain Concentration Associated With Microglial Morphology Changes in Chronically‐Starved Mice

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is associated with hyperactivity, amenorrhea, and brain atrophy. Weight rehabilitation reversed these symptoms, although the underlying pathophysiological mechanisms are mostly unknown. Serum neurofilament light chain (NfL) levels are widely used as a biomarker of neurodegeneration. Based on neuroimaging studies

Resting State fMRI-Guided Fiber Clustering [PDF]

, 2011
Fiber clustering is a prerequisite step towards tract-based analysis of white mater integrity via diffusion tensor imaging (DTI) in various clinical neuroscience applications. Many methods reported in the literature used geometric or anatomic information for fiber clustering.

Reflex “toothbrushing” epilepsy: Seizure freedom after focal ablation assisted by ictal fMRI

Epileptic Disorders, EarlyView.
Abstract A 22‐year‐old female presented with drug‐resistant focal motor seizures with onset at age 14. This manifested as daily episodes of right facial dystonia triggered by toothbrushing, but also by eating, talking, and strenuous exercise. On ictal scalp EEG, there was low‐voltage fast activity over the left pericentral area.

Detecting language network alterations in mild cognitive impairment using task‐based fMRI and resting‐state fMRI: A comparative study

Brain and Behavior
Objective The objective of this study was to investigate the functional changes associated with mild cognitive impairment (MCI) using independent component analysis (ICA) with the word generation task functional magnetic resonance imaging (fMRI) and ...

A Generative-Discriminative Basis Learning Framework to Predict Clinical Severity from Resting State Functional MRI Data

, 2018
We propose a matrix factorization technique that decomposes the resting state fMRI (rs-fMRI) correlation matrices for a patient population into a sparse set of representative subnetworks, as modeled by rank one outer products.

Intrinsic Frequencies of the Resting-State fMRI Signal: The Frequency Dependence of Functional Connectivity and the Effect of Mode Mixing

Frontiers in Neuroscience, 2019
The frequency characteristics of the resting-state BOLD fMRI (rs-fMRI) signal are of increasing scientific interest, as we discover more frequency-specific biological interpretations. In this work, we use variational mode decomposition (VMD) to precisely

Multiscale network activity in resting state fMRI [PDF]

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
The brain is inherently multiscalar in both space and time. We argue that this multiscalar nature is reflected in the blood oxygenation level dependent (BOLD) fluctuations used to map functional connectivity. We present evidence that global fluctuations in activity, quasiperiodic spatiotemporal patterns, and aperiodic time-varying activity coexist ...

The relationship between neuromagnetic networks and cognitive impairment in self‐limited epilepsy with centrotemporal spikes

Epilepsia Open, EarlyView.
Abstract Objective This was an exploratory study designed to examine the alterations in neuromagnetic networks within brain regions involved in cognitive functions in children with self‐limited epilepsy with centrotemporal spikes (SeLECTS). Additionally, it sought to explore the relationship between these neural network differences and cognitive ...
