sentence: This may have significant clinical impact since several icEEG studies showed that ripples are not always generated by epileptogenic areas , but can also represent physiological events generated by non ‐ epileptogenic tissues.3 , 29 , 30 , 31 Previous studies showed that noninvasively localized ripple generators correlate with regions generating interictal spikes22 , 27 or with different approximations of the EZ defined by clinical information.14 , 19 , 22 , 23 , 25 , 26 , 27 However , most of these studies included patients who did not necessarily undergo surgery , with the exception of two MEG studies on patients with focal MRI lesions25 or insular epilepsy.26 Given this paucity of noninvasive studies on surgical cohorts , the prognostic value of scalp ‐ recorded ripples for epilepsy surgery , as yet , remains largely unknown , particularly in children .
