Abstract

Boundary element modeling provides real-time useful localization of spike sources, spike propagation patterns and seizure origins in human epilepsy. EEG source localization of temporal lobe epileptiform discharges using the BEM also correlates with other localizing neuro-imaging techniques. EEG source imaging with the BEM is a non-invasive and useful tool for presurgical evaluation of intractable epilepsy
