The effect of stimulus contrast changes on the binocular visual evoked response (VER) was investigated using pattern reversal VER, dichoptic stimulation, and Fast Fourier Transform. When the stimulus contrast was changed binocularly, the monocular components increased as the contrast increased. The binocular component first appeared at the level of 10% contrast; its magnitude was stable under all recording conditions. When the stimulus contrast was changed monocularly, the eye that received the higher contrast stimulation showed more power in the power spectrum. The binocular component appeared even when the difference in contrast between the two eyes was large. The magnitude of the binocular component was stable under all recording conditions. We concluded that the binocular and the monocular components differ in the magnitude of their responses to a contrast change and speculate that the pathways responsible for the two components are not identical.
使用模式反转视觉诱发电位（VER）、双眼分视刺激和快速傅里叶变换，研究了刺激对比度变化对双眼视觉诱发电位（VER）的影响。当双眼刺激对比度发生变化时，单眼成分随着对比度的增加而增加。双眼成分首先出现在10%对比度水平；其幅度在所有记录条件下都保持稳定。当单眼刺激对比度发生变化时，接受较高对比度刺激的眼睛在功率谱中显示出更大的功率。即使两只眼睛之间的对比度差异很大，双眼成分也会出现。双眼成分的幅度在所有记录条件下都保持稳定。我们得出结论，双眼和单眼成分对对比度变化的反应幅度不同，并推测负责这两种成分的通路并不相同。
