Entropy mapping for epileptiform activity localization

In this paper a new EEG mapping, based on entropy, is introduced to study the synchronization of the electric activity of neuronal sources in the brain. An abnormal synchronization (abnormal order) can result in an epileptic seizure and Renyi's entropy was proposed to measure this order. An EEG dataset from a patient affected by frontal lobe epilepsy was analysed. Entropy showed a very steady spatial distribution and a clear relationship with the region of seizure onset.
