Researchers using resting-state functional magnetic resonance imaging (rs-fMRI) have
applied different static regional measurements to study the intrinsic brain activity (IBA) of …

ABSTRACT Background Functional MRI (fMRI) has been widely used to study abnormal
patterns of functional connectivity at rest in patients with movement disorders such as …

The network approach is increasingly being applied to the investigation of normal brain
function and its impairment. In the present review, we introduce the main methodological …

Cognitive impairment is a common non-motor feature of Parkinson's disease (PD).
Understanding the neural mechanisms of this deficit is crucial for the development of …

Introduction The study aim was to identify longitudinal abnormalities of functional
connectivity and its relation with motor disability in early to moderately advanced stages of …

Parkinson's disease (PD) is a neurodegenerative disorder primarily affecting the aging
population. The neurophysiological mechanisms underlying parkinsonian symptoms remain …

Background Depression is one of the most common non-motor symptoms in Parkinson's
disease (PD), but its pathogenesis is still not very clear. Recently, degree centrality, a voxel …

Longitudinal connectivity studies might guide our understanding of the underlying
neurodegenerative processes. We report the results of a longitudinal study in patients at …

Introduction Our study is using Independent Component Analysis (ICA) to evaluate
functional connectivity changes in Parkinson's disease (PD) in an unbiased manner …

Background Motor‐related brain activity in Parkinson's disease has been investigated in a
multitude of functional neuroimaging studies, which often yielded apparently conflicting …
