Computed EEG Topography (CET) of 74 cases of epilepsy demonstrates the potential utility of this method beyond that of the analog EEG for the quantification and localization of regions of epileptogenesis. For the detection and localization of focal epilepsy, CET was equal to or better than the EEG in 77 p. 100 of cases and provided more evidence of focal abnormality in 8.5 p. 100. The topography of spectral power and of early and late, extravisual, components of the averaged evoked potential to flash were abnormal in the region of interictal spike activity.
74例癫痫患者的计算机脑电图地形图（CET）表明，该方法在癫痫发生区域的量化和定位方面比模拟脑电图更具潜在效用。对于局灶性癫痫的检测和定位，CET在77%的病例中与脑电图相当或优于脑电图，并且在8.5%的病例中提供了更多局灶性异常的证据。在发作间期棘波活动区域，频谱功率以及闪光平均诱发电位早期和晚期、视觉外成分的地形图均异常。
