This review focuses on the present status of inter-ictal surface EEG, simultaneous ictal video-EEG and intracranial EEG in the evaluation of children for epilepsy surgery. This is considered in the context of high-end structural and functional neuroimaging available today. Initially the concept of the epileptogenic zone and its different components are discussed so that it is easier to understand how the EEG helps in localization. Methods of maximizing the yield of the EEG are emphasized. Abnormalities in the inter-ictal and ictal EEG are discussed in some detail. Special emphasis is given to the seizure semiology and how this helps in identifying which lobe is primarily involved. Limitations of surface EEG are then detailed, with special emphasis on young infants. Finally the discussion turns to intracranial EEG. This is used intra-operatively in one stage epilepsy surgery and more definitively extra-operatively in two stage surgery not only to define the epileptogenic zone but also to identify critical cortex.
