Eight patients with secondary generalized epilepsy not alleviated by medical treatment underwent partial callosotomy. During the surgical procedure, they had mesial surface ECoG recordings taken from both frontal and parietal lobes, using large flat multilead platinum electrodes, and simultaneously recordings from a number of scalp positions, using needle electrodes. In all cases studied, this approach demonstrated one or, more commonly, several focal areas of epileptiform activity discharging independently over the mesial aspects of one or both hemispheres. The findings were correlated with the pre- and postoperative EEG patterns, in the light of current concepts of generalized epilepsies.
8例药物治疗无效的继发性全身性癫痫患者接受了部分胼胝体切开术。在手术过程中，使用大型扁平多导联铂电极从额叶和顶叶的内侧表面进行皮质脑电图（ECoG）记录，并同时使用针电极从多个头皮位置进行记录。在所有研究病例中，这种方法显示出一个或更常见的是几个癫痫样活动的局灶性区域，在一个或两个半球的内侧独立放电。根据目前对全身性癫痫的概念，这些发现与术前和术后的脑电图模式相关。
