Topic: epileptogenic zone network

For pre-surgical evaluation of patients with focal seizures, stereoelectroencephalographic (SEEG) signals are routinely recorded to identify the epileptogenic zone network (EZN). This network consists of distant brain regions involved in seizure initiation. However, the mechanisms underlying typical SEEG patterns that occur during the transition from interictal to ictal activity in distant brain nodes of the EZN remain elusive.We analyzed SEEG signals recorded from the EZN (involving three distant neocortical brain regions) in 10 patients during the transition from interictal to ictal activity
