Studying Sub-dendrograms of Resting-state Functional Networks with Voxel-wise Hierarchical Clustering

open access: yesFrontiers in Human Neuroscience, 2016
Hierarchical clustering is a useful data-driven approach to classify complex data and has been used to analyze resting-state functional magnetic resonance imaging (fMRI) data and derive functional networks of the human brain at very large scale, such as ...

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 ...

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 ...

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

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.

Resting state fMRI: A review on methods in resting state connectivity analysis and resting state networks

open access: yesThe Neuroradiology Journal, 2017
The inquisitiveness about what happens in the brain has been there since the beginning of humankind. Functional magnetic resonance imaging is a prominent tool which helps in the non-invasive examination, localisation as well as lateralisation of brain functions such as language, memory, etc.

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 Networks Route Neurodegeneration Patterns in Patients with Progressive Supranuclear Palsy

open access: yesMovement Disorders, EarlyView.
Abstract Background Progressive supranuclear palsy (PSP) is a neurodegenerative disease driven by 4‐repeat τ pathology, which is thought to propagate across interconnected neurons. Objectives We hypothesized that interconnected brain regions exhibit correlated atrophy, and that atrophy propagates network‐like from fast‐declining epicenters to connected

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).
