The use of nasopharyngeal electrodes to study EEG activity of the basilar portions of the brain was introduced by Grinker.1 Gastaut2 first used this technique to evaluate seizure patients.

Despite the ability of nasopharyngeal electrodes to record epileptogenic discharges localized in the uncinate and mesiobasial aspect of the temporal lobe, they have not found wide acceptance, perhaps because of movement artifacts and other technical difficulties. We have been impressed by how easy it is to apply these electrodes and to record excellent tracings during sleep. This article reports the use of this technique in 121 patients suffering from partial seizures with complex symptoms.

Methods.—  Between 1970 and 1974, a total of 204 patients had nasopharyngeal sleep studies at the University of Wisconsin Center for Health Sciences; 121 were selected for review because of a history of partial epilepsy of complex symptoms (psychomotor).

Results.—  Of the 204 patients who
