Interactions between iCAPs across different sleep stages

(A) The probability of different numbers of iCAPs to overlap is displayed for wakefulness and different sleep stages.

(B) The iCAP co-occurrence pertains to the number of time points during which a pair of iCAPs were both active, divided by the total number of time points that at least one of them was active. This was computed separately for similar signed activations (same-signed co-occurrences) or opposite-signed activations (opposite-signed co-occurrences). Co-occurrence was computed for each network (i.e., pairwise co-occurrence of one network with all the other networks).

(C) Mean of classical FC metric (Pearson's r) applied to iCAP time courses.

(D) Mean of normalized mutual information (NMI) of pairwise iCAP time courses. The computation for the co-occurrence between pairs of iCAP is illustrated on the bottom of the figure.
