A significant fraction of the avalanche repertoire occurs exclusively during waking. (A) To assess the significance of the results, significant families were subjected to the shuffling of family labels. This procedure preserves the distribution of family sizes (see Figure 1D), the number of avalanches in each behavioral state, and the times of occurrence of each avalanche. (B) Fraction of avalanches occurring during waking (WK), slow-wave sleep (SWS) and rapid-eye-movement sleep (REM) for each of the 361 significant families of one sample (ranked by WK and then SWS prevalence). The dashed line indicates the boundary that separates waking-specific families from other families. (C) Same as in (B), but for families obtained from one single label-shuffled set. Note that many shuffled families comprising multiple states fall to the left of the dashed line, indicating that the number of the non-shuffled families that are waking-specific is larger. (D) For each data sample (animal/brain region), the fraction of state-specific families is compared to 1000 shuffled sets. Asterisk indicates significant results (p = 0.05). While the state specificity of families that occur during sleep is limited (3/9 samples in SWS and 2/9 in REM), waking-specific families occur significantly in 8/9 samples.
