Using the counterphase-modulated-tritan-metamers method of Wisowaty and Boynton [Vision Res. 20, 895-909 (1980)], we measured the modulation sensitivity function of the blue mechanism on dark backgrounds and on uniform yellow backgrounds that were produced either by illuminating the retina with yellow light or by filling-in of a stabilized retinal image. When measured on yellow backgrounds, temporal modulation sensitivity was markedly reduced whether the background was produced by retinal illumination or by filling-in. This sensitivity reduction has been attributed by other researchers to changes in the transmission characteristics of the blue/yellow pathway caused by yellow adaptation. Our results obtained with backgrounds that appeared yellow due to filling-in indicate that the site of adaptation must be extraretinal as there was no yellow light reaching the retina in the vicinity of the test probe.
采用维索瓦蒂和博因顿[《视觉研究》20, 895 - 909 (1980)]的反相调制 - 蓝绿色觉异常视标法，我们测量了在暗背景以及通过用黄光照射视网膜或填充稳定的视网膜图像而产生的均匀黄色背景上蓝色机制的调制灵敏度函数。当在黄色背景上测量时，无论背景是由视网膜照明还是填充产生，时间调制灵敏度都会显著降低。其他研究人员将这种灵敏度降低归因于黄色适应导致的蓝/黄通路传输特性的变化。我们用因填充而呈现黄色的背景所获得的结果表明，适应位点必定在视网膜外，因为在测试探针附近没有黄光到达视网膜。
