We investigated the influence of eye dominance scaled by 6 tests on the parameters (N80, P100 latency and N80-P100 amplitude) of the white-black-, green-black-, red-black- and blue-black-pattern visual evoked potentials (PVEPs) of 40 healthy subjects (20 males and 20 females) with normal visual acuity. The P100 latency of the white-black PVEPs was, for both sexes, shorter (P less than or equal to 0.001) in the PVEPs of the dominant eyes. This P100 latency shortening could also be verified for both right dominant and left dominant eyes with no significant difference between them. A consistent relationship, however, between the different degrees of eye dominance and the P100 latency shortening could not be established. In contrast to the P100 latency findings the N80 latencies of the white-black-PVEPs and the N80-P100 amplitudes did not show any significant differences with respect to eye dominance. Furthermore, the colour-black PVEPs did not present any differences of latency and amplitude depending on eye dominance. Thus our results give further electrophysiological evidence for eye dominance as a lateralized CNS phenomenon that is not influenced by colour.
我们通过6项测试对40名视力正常的健康受试者（20名男性和20名女性）的白-黑、绿-黑、红-黑和蓝-黑模式视觉诱发电位（PVEPs）的参数（N80、P100潜伏期和N80-P100波幅）进行了研究，以探讨眼优势的影响。在主眼的PVEPs中，无论男女，白-黑PVEPs的P100潜伏期均较短（P≤0.001）。这种P100潜伏期缩短在右优势眼和左优势眼中均得到证实，且两者之间无显著差异。然而，不同程度的眼优势与P100潜伏期缩短之间并未建立起一致的关系。与P100潜伏期的结果相反，白-黑PVEPs的N80潜伏期和N80-P100波幅在眼优势方面未显示出任何显著差异。此外，颜色-黑PVEPs在潜伏期和波幅方面也未表现出取决于眼优势的差异。因此，我们的结果为眼优势作为一种不受颜色影响的中枢神经系统侧化现象提供了进一步的电生理证据。
