      The identification of distinct high-frequency oscillations during spikes delineates the seizure onset zone better than high-frequency spectral power changes.

          Abstract

          Interictal high-frequency oscillations (HFOs, 80-500Hz) can predict the seizure onset zone (SOZ), but visual detection of HFOs is time consuming. Time-frequency analysis can reveal large high-frequency (HF) power changes (80-500Hz) associated with inter-ictal spikes. The present study determines how well the rate of HFOs and spike-related HF power changes were co-localized with SOZ.
