Processing of Epileptic EEG

Processing of epileptic EEG is required for better understanding of the mechanisms underlying the generation and propagation of seizure electrical activity, as well as for mapping of epileptic foci in patients with intractable focal epilepsy who are candidates for surgery. Most processing methods applied to the EEG require linearity; but, before the question of linearity/non linearity is handled, the non stationary character of the EEG signal has to be tackled.
