Abstract

Background and aims: Previous neuroimaging studies using task stimulation data have found hyperactivation in the cerebellum and motor cortex and hypoactivation in the basal ganglia in patients with Parkinson's disease (PD). However, RESTING STATE analysis and FUNCTIONAL CONNECTIVITY between regions are rarely investigated in PD.Material & Methods: In the present study, three important problems have been considered: First, we calculated the LOW FREQUENCY FLUCTUATIONs in RESTING STATE PARKINSON DISEASE and compared to the controls. Second, we analyzed the REGIONAL HOMOGENEITY for measuring the local similarity between PD and controls and third the FUNCTIONAL CONNECTIVITY and correlation between regions in PD were investigated.Results: The results from group analysis on LOW FREQUENCY FLUCTUATION maps confirmed the previous finding on task stimulation data and showed hyperactivation in the cerebellum and motor cortex and hypoactivation in the basal ganglia in PD. Moreover, REGIONAL HOMOGENEITY analysis did not show any significant difference between two groups. In addition, the results of statistical tests on FUNCTIONAL CONNECTIVITY showed the negative significant correlation in LOW FREQUENCY FLUCTUATIONs between some regions in motor area and basal ganglia. This negative connectivity is only in PD and there are positive significant correlations within motor area and basal ganglia regions in control groups.
