Cortical distributions of SEPs and high-**frequency** **oscillations** to median nerve stimulation in Patient 5. (A) Typical high-**frequency** **oscillation** potential recorded at electrode A5. (B) The location of recording electrodes. (C) Cortical distributions of the SEPs and high-**frequency** **oscillations**. P20/N20 are distributed diffusely around the primary hand sensorimotor area, while P25 is elicited in a restricted cortical area. Most **oscillation** potentials show a cortical distribution similar to that of P20/N20. Two later **oscillations** (n21 and p22) are elicited in a restricted cortical area similar to P25.
... Typical examples of high-**frequency** **oscillations** to median nerve stimulation recorded with a restricted bandpass filter of 500–2000 Hz compared with SEPs recorded with a wide bandpass filter of 30–2000 Hz. The SEPs and high-**frequency** **oscillations** were recorded at the same precentral electrodes (A1 in Patient 2 and A5 in Patient 5). Note the better isolated **oscillation** potentials on restricted filtering as a result of the attenuation of slower SEP components. Most of the **oscillation** potentials can be identified with both bandpass filters. p22 can only be seen on restricted bandpass filtering in Patient 2. The latencies of **oscillations** differed by 0.11 ms for the two different bandpass filters.

... Cortical distributions of SEPs and high-**frequency** **oscillations** to median nerve stimulation in Patient 7. (A) Typical high-**frequency** **oscillation** potential recorded at electrode C1. (B) The location of recording electrodes on the 3-dimensional MRI reconstruction. (C) Cortical distributions of the SEPs and high-**frequency** **oscillations**. Most **oscillation** potentials are distributed similar to or more diffusely than P20/N20. Three later **oscillations** (n18, p18 and n19) are elicited in a restricted cortical area similar to P25.
... High-**frequency** **oscillation**... The locations of the subdural electrode array and functional brain mapping in each patient. SEPs and high-**frequency** **oscillations** were recorded from the electrodes enclosed by solid lines. Electrodes A7 and C4, and A4 were not used for recording because of disconnection of the wires in Patients 5 and 7, respectively. CS, central sulcus.

Diagram of the MNI detector. (A) baseline detector. (B) HFOs detection in channels with baseline. (C) HFOs detection in channels with continuous high **frequency** activity. If more than 5s/min of baselines are found, HFOs are detected with respect to the baseline segments (B). If less than 5s/min of baseline were detected, HFOs are detected with respect to the entire EEG segment in an iterative way (C). WE: wavelet entropy; Rxx: autocorrelation; th: Threshold.

Out of the 7994 PosAnd HFOs, 554 corresponded to FR that did not co-occur with a visually marked ripple. The peak **frequencies** of these events included not only the 250–500Hz band but also the 80–250Hz band. All these events were visually marked as FR using a high-pass filter at 250Hz. Two examples are presented. Top: FR with a peak **frequency** at 150Hz; Bottom: FR with a peak at 265Hz. The unfiltered EEG, the filtered EEG above 80Hz and the filtered EEG above 250Hz are shown.
