Research Overview: High frequency oscillation (HFO) has been known as a promising electrographic biomarker for epiletic tissue for decades. To this end, we characterized HFO networks through functional connectivity analysis of clinical intracranial EEG data from patients who have undergone resective surgery (pre-processed EEG dataset provided for one good outcome Engel I and one poor outcome Engel III patient). From the networks, we performed centrality analyses (results of which are also provided) to evaluate how HFO features can be used to predict patient outcome.
Software requirements: Matlab R2021a or above (other toolboxes may be required)
Instructions:
Unzip "Data.7z" file. /BKGEEG - Preprocessed background (nonHFO) EEG data (.mat) /CombinedData - Final centrality and hfo features for all patients (.mat) /HFOEEG - Preprocessed HFO specific EEG data (.mat). These data show the raw filtered and RMS 'samples' that were used for the analysis /PatientData - Patient level data (.mat)
