A Method to Separate Contributions of Different Foci in Interictal Epileptic Activity
So far in MEG studies of epilepsy the main attention has been devoted to patients, showing only a single focus. However, in many patients with pharmacoresistent epilepsy, who are candidates for neurosurgical therapy, a clear unifocal picture of the interictal activity is not found. More probably, the interictal electric and magnetic activity can be referred to a number of separated generators. In order to localize these foci by MEG, it is necessary to extract their contribution out of the measured magnetic activity.
