To study the possibility of the clinical application of the electrically evoked response (EER) of the visual system, we analyzed P2 of EER as well as P100 of flash VEP by means of topography and dipole-tracing. By applying a constant electric current of 1.0 mA (duration 5 msec, frequency 1.39 Hz) and a strobo flash light of 0.6 Joules (frequency 1.39 Hz) to each eye, P2 and P100 were recorded respectively. It was found that the source generators of P2 and P100 showed the same localization and dipole vector. The results indicated flat the significance of P2 in applying EER clinically was comparable to the P100 of VEP.
为研究视觉系统电诱发反应(EER)临床应用的可能性,我们通过地形图和偶极子追踪分析了EER的P2以及闪光视觉诱发电位(VEP)的P100。对每只眼睛分别施加1.0毫安的恒定电流(持续时间5毫秒,频率1.39赫兹)和0.6焦耳的频闪闪光灯(频率1.39赫兹),分别记录P2和P100。结果发现,P2和P100的源发生器显示出相同的定位和偶极子矢量。结果表明,P2在EER临床应用中的意义与VEP的P100相当。
