1. Additional electrodes can be used to supplement the standard System.115 Ninety-seven percent of spikes are detected using additional anterior temporal region surface electrodes (T1 and T2), whereas 58% of the spikes are detected using only System electrodes. Anterior temporal electrodes (T1 and T2) are able to detect nearly all interictal epileptiform discharges recorded by the foramen ovale electrode. Therefore, assuming that the location of the foramen ovale electrode is analogous to that of sphenoidal electrodes optimally implanted under fluoroscopy, the use of sphenoidal electrodes in routine interictal investigations appears not to be justified.116
