Differences in the brain sensitivity to color responses may cause significant differences in the latency and amplitude of the electroencephalographic (EEG) component. This paper investigated the electroencephalography features of binocular color fusion and binocular color rivalry when watching stereoscopic three-dimensional (3D) displays. EEG experiments were conducted on a conventional 3D display platform. Eight subjects were involved to analyze differences in the event-related potential (ERP) and power spectrum when the brain perceived binocular color fusion and binocular color rivalry. Results show that: 1) the latencies of ERP components N1 and P2 of binocular color fusion were shorter than that of binocular color rivalry, 2) the amplitudes of the ERP components P2 and P3 of binocular color fusion were greater than that that of color rivalry, and 3) the left hemisphere was dominant for binocular color rivalry while the right hemisphere was greater involved in binocular color fusion. These results indicate that during the initial and mid-term cognitive processing, the brain response to binocular color fusion is faster than binocular color rivalry. Both binocular color fusion and rivalry involve visual post-processing, but binocular color fusion requires a greater allocation of neural resources. Power spectrum analysis revealed the cerebral lateralization in binocular color fusion and rivalry, it suggested that the way the brain processes this binocular input can have effects on its function.
大脑对颜色反应的敏感性差异可能会导致脑电图（EEG）成分的潜伏期和波幅出现显著差异。本文研究了观看立体三维（3D）显示时双眼颜色融合和双眼颜色竞争的脑电图特征。在传统的3D显示平台上进行了脑电图实验。八名受试者参与分析大脑感知双眼颜色融合和双眼颜色竞争时的事件相关电位（ERP）和功率谱差异。结果表明：1）双眼颜色融合的ERP成分N1和P2的潜伏期比双眼颜色竞争的潜伏期短；2）双眼颜色融合的ERP成分P2和P3的波幅比颜色竞争的波幅大；3）双眼颜色竞争时左半球占主导，而双眼颜色融合时右半球参与度更高。这些结果表明，在认知处理的初期和中期，大脑对双眼颜色融合的反应比双眼颜色竞争更快。双眼颜色融合和竞争都涉及视觉后处理，但双眼颜色融合需要更多的神经资源分配。功率谱分析揭示了双眼颜色融合和竞争中的大脑偏侧化现象，这表明大脑处理这种双眼输入的方式会对其功能产生影响。
