Neuroimaging advances over the past several decades have provided increased
understanding of the structural and functional brain changes that occur with Parkinson's …

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 …

Cognitive impairment is a common disabling symptom in PD. Unlike motor symptoms, the
mechanism underlying cognitive dysfunction in Parkinson's disease (PD) remains unclear …

Functional MRI (fMRI) has been widely used to study abnormal patterns of brain connectivity
at rest and activation during a variety of tasks in patients with idiopathic Parkinson's disease …

Resting-state functional magnetic resonance imaging (RS-fMRI) studies have been
extensively applied to analyze the pathophysiology of neurodegenerative disorders such as …

Functional neuroimaging techniques provide important insight into the pathophysiology of
neurodegenerative disorders such as Parkinson's disease (PD) in-vivo. Recently, resting …

Disturbances in intrinsic activity during resting-state functional MRI (rsfMRI) are common in
Parkinson's disease (PD), but have largely been studied in a priori defined subnetworks …

The diagnosis of Parkinson's disease (PD) remains still clinical; nevertheless, in the last
decades, the rapid evolution of advanced MRI techniques has made it possible to detect …

Background Resting-state functional magnetic resonance imaging (RS-fMRI) has frequently
been used to investigate local spontaneous brain activity in Parkinson's disease (PD) in a …

Background Cognitive impairment is a common non-motor symptom in Parkinson's disease.
So far, the underlying pathophysiology remains unclear. Several alterations in functional …
