5. Source localisation of epileptiform activity in epilepsy of temporal lobe origin
Abstract : In patients with drug resistant partial epilepsy, who are under consideration for epilepsy surgery, interictal and ictal EEG recorded with extracranial electrodes plays an important role in the localisation of the seizure onset area. During the past years, methods have been developed, which can be used to estimate the location of the source of epileptiform activity in the brain from extracranial EEG data. READ MORE
