摘　　要：本文报告11例头颅扫描阴性的癫痫患者的脑电研究,11例均经EEG、BEAM等检查发现颞(或额)叶原发棘(尖)波等痫性放电灶。术中在ECOG定位指导下切除痫性病灶,经病理检查发现8例神经细胞胶质增生及神经细胞肿胀变性;3例为脑隐匿性微血管畸形。EEG棘(尖)波等痫灶和局灶性慢波有一定的病理基础,EEG波形改变的类型和预后有相互关系。This paper reports 11 cases of brain electrical activity study of epileptic patients with negatire CT. In all cases, epileptic focuses of spike and sharp waves in the temporal or frontal were found by EEG, BEAM. Focus resection were guided by ECoG, and glial proliferation, degeneration and focal hemorrhage were proved in 8 cases, obscure miccrovascular malformation in 3 cases Not only brain functional disorders but also pathological changes without morphologic findings by naked eye were found in our operated cases. It was verified that spike and sharp wave and slow wave focus had some basis on pathology and relation with the prognosis. Spike and sharp wave focuses irt temporal implied the causes of glial proliferation, Ammon's sclerosis, microvascular malformation or hamartoma, and good results could be obtained through surgical resectiort of focus; whereas bilateral and diffused spike, sharp waves, which existed in diffused pathological changes, had no clinical significance for operation.
