Electroencephalogram with sphenoidal needles in sleepwalkers

The etiology of sleepwalking is controversial, the theory that sleepwalking is an epilepsy-like symptom being mostly discounted. Electroencephalogram records, obtained by using sphenoidal needles, are presented as a useful technique and aid to etiological and topical diagnosis. A temporal focus of waves of 4-6 cps was recorded which was not found in the routine EEG procedures. The question is thus raised as to whether sleepwalking may be a result of a paroxysmal disorder in the temporal lobe.
