ELECTROENCEPHALOGRAPHY AS A LOCALIZING TOOL

The immature brain is not a miniature adult brain, and adult epilepsy concepts and protocols do not necessarily apply to infant epilepsy sur gery. The epileptogenic zone is conceptually, and often also topograph ically, distinct from both the ictal-onset zone and the irritative zon e (interictal spiking). This distinction is especially important in pe diatric evaluations. The most reliable localizing aspects of the EEG a re interictal nonepileptiform abnormalities traditionally associated w ith structural lesions.
