Using regional homogeneity (ReHo) method, the current study explore the abnormal spontaneous neural activity of resting state in early PD patients. Ten early PD patients were compared with eleven controls. After data preprocessing, ReHo analysis was performed using software REST. The increased ReHo was showed in bilateral frontal lobe, left parietal lobe, left cerebellum, right parietal Lobe and precuneus; Meanwhile, the decreased ReHo was showed in left frontal Lob, left occipital lobe and calcarine. These results revealed the pathophysiological mechanisms underlying early PD and demonstrate the feasibility of using ReHo as a useful tool to monitor cerebral dysfunction in PD
