Statistical and scaling behaviours of HFOs, more examples. Distributions of on-interval T of IMF 5 (channel 6 of rat 9): (a–f) for files 1–19, 32–57, 63–72, 78–97, 98–118 and 119–149, corresponding to the pre-stimulation state, post-stimulation state, evolving towards seizure, status epilepticus phase, epilepsy latent period and spontaneous/recurrent seizure period, respectively. The numbers of on-intervals are 354 499, 561 669, 300 291, 458 649, 293 118 and 438 919 for (a–f), respectively. An algebraic distribution is observed with different exponents for different segments, where the exponents are $-5.7$, $-3.3$, $-2.9$ for dash-dotted line, solid line and dotted line, respectively. The criterion for choosing the threshold $A_{\mathrm{c}}$ is the same as in figure 9.
