Abstract:
objective:To discuss the characteristics and localizing significance of presurgical scale ambulatory electroencephalo-gram(AEEG)in patients with supratentorial tumor by comparison their electrocorticography(ECOG).Methods:124 subjects were collected in our hospital.All patients were monitored by the scalp AEEG before surgeries and ECOG during oprating.The interictal epileptiform discharges of ECOG were divided into five catalogs.Ⅰ:no spikes.Ⅱ:isolated spikes.Ⅲ:repetitive spike-wave pattern.Ⅳ:intermittent spikes,polyspikes waves burst.Ⅴ:continuous hyper-spikes and sharps.A,B,C,D and E were represented on the scalp AEEG which corresponded the above ECOG classification.Then AEEG and ECOG were analyzed.Re-sults:(1)The scalp AEEG was abnormal in 83.87% of all subjects before surgery.Ⅱ type and Ⅲ type on ECOG did not appear easily on the scalp AEEG(P
