Classification of Scalp EEG States Prior to Clinical Seizure Onset
Objective: To investigate the feasibility of improving the performance of an EEG-based multistate classifier (MSC) previously proposed by our group.
Epileptogenic Source Imaging Using Cross Frequency Coupled Signals from Scalp EEG
The epileptogenic zone (EZ) is a brain region responsible for seizure genesis. This study describes a novel EEG source imaging (ESI) method to estimate the EZ which uses cross frequency coupled potential signals (SCFC) derived from scalp EEG. Results were validated using 1) known surgical resections for Engel I-IV patients, and 2) through forward modelling with noise simulation. The SCFC demonstrated significant advantages over “raw” scalp EEG.
