Stimulus and analysis parameters have been adjusted to provide optimum conditions for producing and recording the early components of flash visual evoked potentials. A visual evoked subcortical potential (VESP) of mean latency P23-N28-P34 has been recorded in 86% of subjects. The triphasic wave was maximal at an electrode position slightly posterior to the Rolandic/sylvian fissure and topographically separate from the lid electroretinogram and the visual evoked cortical potential. Monocular stimulation shows bilateral reduction of the amplitude of the VESP, indicating that the wave is independent of the retina and optic nerve and must be arising from a postchiasmal site.
已调整刺激和分析参数，以提供产生和记录闪光视觉诱发电位早期成分的最佳条件。在86%的受试者中记录到平均潜伏期为P23-N28-P34的视觉诱发电位皮层下电位（VESP）。三相波在罗兰多/外侧裂稍后方的电极位置处最大，在地形上与眼睑视网膜电图和视觉诱发电位皮层电位分开。单眼刺激显示VESP波幅双侧降低，表明该波独立于视网膜和视神经，必定起源于视交叉后部位。
