A study of electroencephalography data from 29 people with epilepsy finds that although high-frequency oscillations have been proposed as biomarkers to localize epileptic tissue for surgical resection, the concurrence of high-frequency oscillations with epileptiform spikes differentiates pathological oscillations from nonepileptiform signals and provides a potential tool for presurgical diagnosis and postsurgical evaluation, according to the authors.
