Abstract

The relative spectral sensitivity of blue-sensitive pigeon cones was determined using flicker-photometry based on mass ERG-responses from intact subjects during high-level light adaptation. The resulting spectral sensitivity curve can be mimicked by a P460 nomogram screened by an oil-droplet that absorbs 50% at 466 nm. Comparison of the curve with the nomogram indicates that on the average less than 10% of the light that excites the blue-sensitive cones is guided past or diffracted around their oil-droplets.

摘要

利用基于完整受试者在高水平光适应期间的群体视网膜电图反应的闪光光度法,测定了蓝敏感鸽视锥细胞的相对光谱敏感性。所得的光谱敏感性曲线可以由一个在466nm处吸收50%的油滴筛选的P460列线图模拟。将该曲线与列线图进行比较表明,平均而言,激发蓝敏感视锥细胞的光中,只有不到10%的光被引导穿过或绕开它们的油滴。
