(a) (Left). Average FNC plots. We calculated the mean FNC (z-fisher score) based on the aggregated FNC matrix of all individuals. (a) (Left). Block plot of mean FNC matrix between model orders. The ICNs in this FNC matrix were sorted by domains first, and within each domain, ICNs were sorted by model orders (from 25 to 100). The dotted lines in each domain divide different model orders (b) (Right). Finger plot of mean FNC matrix between model orders. ICNs within each model order were sorted in the order of CR, CC, DM, SM, SB, TP, and VS. As we can see in the plot, DM from model order 25 shows strong anticorrelations with SM and TP of model order 100; similar anticorrelations were also observed between model orders 75 and 100, which did not show up in the other sections of the matrix.
