Introduction: The characteristic motor symptoms in Parkinson’s disease (PD) are often accompanied by cognitive, emotional and motivational deficits, which are modulated by dysfunctions of the fronto-striatal loops. The dorsolateral prefrontal cortex (DLPFC) is known to be involved in executive functioning. While activations of the DLPFC during executive tasks are well described, the impact of resting state functional connectivity (FC) of the DLPFC on cognitive changes remains to be specified. In a first step, changes in FC of the DLPFC in PD patients are determined. Methods: We examined 53 PD patients and 16 age…
