In summary, the abovementioned findings show differences between the resting state and movement state-related PAC, especially in patients. These results were not in direct congruence with the behavioral results. In the pressing task, state-related PAC differed between patients and controls, whereas motor behavior was similar. In contrast, in the tapping tasks, state-related PAC was remarkably similar between patients and controls, whereas motor behavior was different. This suggests that abnormal enhancement of PAC per se is unlikely to be directly related to motor impairment.
