Patient datasets accessed through IEEG Portal (http://www.ieeg.org). Age at seizure onset and at electrode implant surgery are noted. Location of seizure onset (lobe) and etiology are clinically determined through medical history, imaging, and long-term invasive monitoring. Seizure types are SP (simple-partial), CP (complex-partial), CP + GTC (complex-partial with secondary generalization), or GA (generalized atonic). Counted seizures were recorded in the epilepsy monitoring unit. Interictal epochs were 5 min in duration and at least 2 h away from any seizure. Clinical imaging analysis concludes L, Lesion; NL, nonlesion. Surgical outcome is reported by both Engel score and ILAE score (scale: I--IV/V, seizure freedom to no improvement; NR, no resection; NF, no follow-up). M, male; F, female.
