我们使用 10' 直径闪光灯在 104td 572 nm 背景下观察，测量了高达 5° 偏心率的增量阈值。我们发现两种不同的灵敏度分布，一种闪光波长为 410-470 nm，另一种为 520-580 nm。光谱灵敏度图分别指示两个轮廓的蓝色敏感锥体和绿色敏感锥体。蓝色敏感视锥细胞的灵敏度在 1° 偏心率时达到最大。较大偏心率下的测量容易适应测试场。蓝色敏感视锥细胞的光收集面积提升到一定幂后遵循蓝色敏感视锥细胞的灵敏度分布。
We measured increment thresholds up to 5° eccentricity using a 10′ dia flash viewed against 104td of 572-nm background. We found two distinct sensitivity profiles, one with flash wavelengths 410–470 nm and another with 520–580 nm. Spectral sensitivity plots indicate blue-sensitive cones and green-sensitive cones for the two profiles, respectively. Sensitivity of blue-sensitive cones is maximum at 1° eccentricity. Measurements at greater eccentricities are susceptible to adaptation to test field. The light-collecting area of blue-sensitive cones raised to a power follows the sensitivity profile of blue sensitive cones.
