Clinical characteristics, surgical plan, and seizure outcome for all patients in study. Group A is patients 1–7 and Group B is patients 8–10. Age and Epilepsy onset numbers are indicated in years. Postoperative score is indicated by Engel class I-IV. The scalp EEG pattern refers to initial changes related to the seizure. SP: sphenoidal electrodes. The ‘=’ symbol indicates isopotential at the two listed electrode sites. The ‘>’ symbol indicates two populations of IEDs with one electrode site predominating.
