Most of the attempts for source imaging in epilepsy focused on localising the interictal epileptiform discharges. Although localizing ictal EEG patterns (seizure-onset zone) is crucial for decision-making in epilepsy surgery, source imaging of ictal patterns has received surprisingly little attention until now. This is mainly because of technical and methodological difficulties. This lecture summarises the main challenges for source imaging of ictal patterns and will present possible solutions, with main emphasis on averaging ictal waveforms and on phase-mapping. Source imaging of ictal patterns is feasible and provides valuable clinical information for the presurgical workup.
