From: Interictal invasive very high-frequency oscillations in resting awake state and sleep

Visualisation of the results of rest and sleep study on patient n. 102. Green zone = SOZ; Red points = contacts on electrodes with either Rs, FRs, VFRs or UFRs; The reduction of the number of contacts with high-frequency phenomena from Rs to UFRs in both rest and sleep study is shown; Rest VHFOs better match with SOZ than rest HFOs; Rest VHFOs correspond better to SOZ than sleep VHFOs.
