Magnetoencephalographic localization of subdural dipoles in a patient with temporal lobe epilepsy



Magnetoencephalographic localization of subdural dipoles in a patient with temporal lobe epilepsy



Epilepsia 32(5): 635-641



We report magnetoencephalographic localization of subdural electrode dipoles placed at the basal and mesial surfaces of the temporal lobe in a patient with temporal lobe epilepsy. The locations of the three dipoles were predicted from their magnetic fields with a computer model of the head as a conducting sphere. The predicted locations were within 1, 3, and 4 mm of the actual locations. These results, obtained in an area of the brain from which epileptiform discharges are frequently recorded, strongly support the capability of magnetoencephalography to accurately localize electrical events in this brain region.
