D) Electrode implantation. Left panels: implantation in the right hemisphere showing lateral view (upper), insular view (middle) and hippocampal view (lower). Right panels: implantation in the left hemisphere showing lateral view (upper), insular view (middle) and hippocampal view (lower). (E, F) SEEG recording (amplitude: 750 mV/cm, low-pass filter: 120 Hz, high-pass filter: 0.530 Hz). TP: temporal pole; STS: superior temporal sulcus; STG: superior temporalgyrus; MTG: middletemporalgyrus; LOC: lateraloccipitalcortex; PCG: post-central gyrus; tab: left temporo-basal area; lIOA: left insulo-opercular area. (E) Seizure onset showing electricalonsetwithafastdischargefromtheelectrodesexploringthelesion(OI 1-2)(1) withfastpropagationon the temporal pole, fast discharge on the insula (arrow) at clinical onset (6 seconds after the electrical onset) (2), with movement, tachycardia and facial contraction (7 seconds after the electrical onset) (3). Note the rhythmic activity from the opercular electrodes and the theta activity from OG1 facing the lesion on the left (continued).
