Differences over time between young and old in across-network coupling and the association with memory performance. Top row: partial correlations (r-to-z transformed) between networks over time for both groups (error bars indicate 1 standard error). Bottom row: correlations between on the one hand the partial correlations values of the coupling between the default mode network and the executive network, and on the other hand the d′ prime parameter for both groups. There is a significant association for older adults after encoding and before retrieval, for younger participants only before retrieval. ^*p < 0.05; ^**p < 0.01; ^***p < 0.001.
