Time varying analysis of dynamic resting-state functional brain network to unfold memory function

open access: yesNeuroscience Informatics
Recent advances in brain network analysis are largely based on graph theory methods to assess brain network organization, function, and malfunction. Although, functional magnetic resonance imaging (fMRI) has been frequently used to study brain activity ...

Pathophysiological Role of Primary Motor Cortex in Essential Tremor

open access: yesMovement Disorders, EarlyView.
Abstract Background Essential tremor (ET) is one of the most prevalent movement disorders. However, the complete understanding of ET pathophysiology remains elusive. Objective To explore the pathophysiological role of primary motor cortex (M1) in ET, specifically exploring its neurophysiological changes and their correlation with voluntary motor ...

Molecular‐Informed Network Analysis Unveils Fatigue‐Related Functional Connectivity in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Fatigue in Parkinson's disease (PD) is a prevalent and debilitating non‐motor symptom. Despite its significant impact on quality of life, the underlying neurochemical and network‐based mechanisms remain poorly understood. Objectives This observational study applied a multimodal imaging approach to explore potential links between the

Resting-state functional magnetic resonance imaging for language preoperative planning

open access: yesFrontiers in Human Neuroscience, 2016
Functional magnetic resonance imaging, fMRI, is a well-known non-invasive technique for the study of brain function. One of its most common clinical applications is preoperative language mapping, essential for the preservation of function in ...

Brain entropy and human intelligence: A resting-state fMRI study

open access: yesPLoS ONE, 2018
Human intelligence comprises comprehension of and reasoning about an infinitely variable external environment. A brain capable of large variability in neural configurations, or states, will more easily understand and predict variable external events ...

A NIRS–fMRI study of resting state network

open access: yesNeuroImage, 2012
Resting state functional connectivity, which is defined as temporal correlation of spontaneous activity between diverse brain regions, has been reported to form resting state networks (RSNs), consisting of a specific set of brain regions, based on functional magnetic resonance imaging (fMRI).

Neural Mechanisms of Object Location Memory in Huntington's Disease

open access: yesMovement Disorders, EarlyView.
ABSTRACT Background Object‐location memory impairment in Huntington's disease (HD) occurs from premanifest period and declines as HD progresses, however, pathogenesis of object‐location memory is unknown. The striatum and hippocampus are affected in HD, functionally interacting allowing intact object‐location memory.

Double Temporal Sparsity Based Accelerated Reconstruction in Compressed Sensing fMRI

open access: yes, 2017
A number of reconstruction methods have been proposed recently for accelerated functional Magnetic Resonance Imaging (fMRI) data collection. However, existing methods suffer with the challenge of greater artifacts at high acceleration factors. This paper

Hemodynamic response function (HRF) variability confounds resting‐state fMRI functional connectivity

open access: yesMagnetic Resonance in Medicine, 2018
fMRI is the convolution of the hemodynamic response function (HRF) and unmeasured neural activity. HRF variability (HRFv) across the brain could, in principle, alter functional connectivity (FC) estimates from resting‐state fMRI (rs‐fMRI).
