(A) For each trial of the free recall task, subjects were asked to encode 12 nouns, then performed an arithmetic distraction that was followed by the verbal recall phase. (B) Linear mixed-effects models revealed that IED rates were higher for contacts in the SOZ relative to contacts outside of the SOZ (Non-SOZ) (p < 0.001). (C) IED rates were also shown to be higher in the SOZ relative to the Non-SOZ, irrespective of the SOZ location (p < 0.01); however, there was no difference in IED rates between the stratified Non-SOZ regions (p = 0.99). Bars represent 95% confidence intervals. * p < 0.05, ** p < 0.01, *** p < 0.001
