Topic: common average reference

Epilepsy is a neurological disorder characterized by recurring, unprovoked seizures. For refractory epilepsy patients, resective surgery does not always result in seizure freedom. The purpose of this study was the localization of seizure activity from sEEG data using dynamic mode decomposition (DMD) to aid in resective surgery planning. Analysis was performed on retrospective sEEG data. A band pass filter was applied between 1 and 40 Hz. Individual Component Analysis was performed to reduce noise. A common average reference filter was applied. The data were down sampled to 128 Hz. A two-minute
