为了证实癫痫病人的癫痫样放电存在左侧大脑半球占优势,本文对纽约医学中心脑电图(EEG)室,使用16导EEG仪,按国际标准10～20系统法,把头皮电极、单极和双极导联记录到的1360份EEG进行分析。凡出现不对称的波峰,根据左或右侧大脑半球一侧波幅高者,或痫样放电的重复出现率,或两侧电活动不对称而其中一侧占优势者制表进行统计。 In order to confirm that epileptiform discharges of epilepsy patients are dominant in the left hemisphere, we use the 16-lead EEG instrument in the EEG room of New York Medical Center, according to the international standard 10-20 system method, the scalp electrode, monopolar And 1360 EEGs recorded by the bipolar lead were analyzed. Where asymmetric peaks, according to the left or right hemisphere side of the high volatility, or recurrence of epileptiform discharges, or both sides of the asymmetric electrical activity and the dominant side of the tabulation statistics.
