In this study, we explored the dynamics of Parkinson’s disease (PD) brain network function utilizing the co-activation pattern (CAP) analysis emphasizing sensorimotor network (SM) function during resting-state. We modified the routine to calculate group dominant CAPs (d-CAPs) and proposed a novel way to obtain within-subject CAP switching-rate. Reduced dynamics of the SM network in PD was demonstrated by both decreased number of d-CAPs and decreased switching-rate, which corroborates electrophysiologic data.
