Figure 8
Ictal SEEG activity showing a short startle-reflex seizure elicited by a sudden noise (hand clap: green vertical line). LVFA superimposed on a slow wave on the middle and lateral contacts of electrode C (IFS in the premotor cortex). A phase reversal was observed between C3-C4 and C5-C6. The discharge propagated over the M electrode (primary hand motor area), L electrode (primary face motor area) and A (IFG gyrus in the premotor cortex). Note the associated short myogenic potential in the contralateral deltoid. Montage and filters as for figure 5. ACC: anterior cingulate cortex; IFG PFC: lateral prefrontal cortex, frontal inferior gyrus; IFG PMC: lateral premotor cortex, frontal inferior gyrus; M1C: primary motor cortex (precentral gyrus); MCC: middle cingulate cortex; MFG PFC: lateral prefrontal cortex, frontal middle gyrus; MFG PMC: lateral premotor cortex, frontal middle gyrus; OpF: frontal operculum; OpR: Rolandic operculum; OpP: parietal operculum; OpT: temporal operculum; Post INS: posterior insular cortex; S1C: primary sensory cortex (postcentral gyrus); SFG PFC: lateral prefrontal cortex, frontal superior gyrus; SFG PMC: lateral premotor cortex, frontal superior gyrus; Sup INS: superior insular cortex.
