Abstract
A cortical potential imaging technique (CPI) was used to estimate the cortical potentials from scalp EEG recordings in two pediatric epilepsy patients. The pre-operative interictal spikes for 2 patients were applied to CPI by using realistic geometry head models built from individual MRI data. The localized areas of activity were revealed by CPI, as confirmed by neurosurgical resections and subdural ECoG recordings. The present study suggests that CPI may become a useful alternative for noninvasive imaging of epileptiform activity from pre-operative EEG recordings.
