Fig. 1
Example rates of HFOs. The HFO rate per epoch of NREM sleep is shown for four example patients. All NREM data are concatenated together, with white vertical lines indicating breaks between NREM periods. a A small group of channels have high HFO rates, though the highest channel varies over time. b One channel is high but alternates with arbitrary groups with much lower rate. c Many channels are high in an organized cluster and all appear well correlated. d Much more complex patterns are also observed, in which different channel groups dominate on different days. Channels in the resected volume (RV) and clinically determined seizure onset zone (SOZ) are ordered together, as are channels with similar temporal dynamics in HFO rates. Note that patients in a and b did not have a resection
