We propose a novel group CAP analysis method to investigate temporal dynamics of specific resting-state networks. Our data-driven method computes less spatially overlapping d-CAPs for each group. We compare network-dynamics between different populations using d-CAP based measurements. Using simulation, we demonstrate that the proposed method is able to determine spatially less overlapping d-CAPs for each group accurately. Using real fMRI data, we find reduced network-dynamics of most networks in PD subjects as hypothesized, which corroborates and expands upon previous electrophysiologic reports.
