Module-based network metrics during resting-state and task. (A) Mutual information (MI) between resting-state network partitions and those derived from the task conditions. Note that we quantified the mutual information (MI) between each subject’s resting network partition to those derived from the four task conditions. In this manner, MI during resting-state would be equal to 1 because it is the network used for comparison and is therefore not plotted in A. Modularity (B) and lateral frontal (C) and occipital (D) participation coefficient (PC) for resting-state and task conditions. Centers of mass for lateral frontal and occipital AAL atlas nodes used to calculate PC are plotted on a sagittal view of the brain in C and D, respectively. Data are presented as mean ± SEM. Pairwise comparisons between younger and older groups across the task conditions were conducted for metrics showing significant age group by task condition interactions. *** P < 0.001; ** P < 0.01; * P < 0.05; ~ P < 0.1.
