Abstract

The purpose of the study was to investigate the accuracy of location of equivalent current dipoles estimated by the dipole tracing method (DT) utilizing a realistic 3-shell (scalp-skull-brain) head model (SSB-DT). Three patients with intractable complex partial seizures, diagnosed as having typicaltemporal seizures were investigated. We recorded the interictal spike potentials with surface electrodes (International 10/20 system) and with intracerebral depth electrodes simultaneously. We compared the location of dipoles of the spikes estimated by the SSB-DT with the focus of the spikes determined by the recording from the depth electrodes. We found that the locationof the dipoles estimated by SSB-DT corresponded to the location of the depth electrodes, which could record the epileptic spikes. This finding provedthat SSB-DT is reliable and valid for estimating neural activity in deep locations such as the limbic system. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.
