Abstract

The photopic spectral sensitivity of the yellow field of the pigeon's retina to UV light was determined electrophysiologically. The sensitivity curve could be approximated with a model in which the activity of only two cone types were incorporated. In this model, the first type of cone had a maximum sensitivity at 366 nm and was combined with an oil droplet that is completely transparent in the UV wavelength range. The second type had a sensitivity maximum at 415 nm and was associated with an oil droplet cutting off light below 390 nm.

摘要

通过电生理学方法测定了鸽子视网膜黄斑对紫外光的明视觉光谱敏感性。该敏感性曲线可以用一个仅包含两种视锥细胞类型活性的模型来近似。在这个模型中，第一种视锥细胞在366nm处具有最大敏感性，并与一个在紫外波长范围内完全透明的油滴相结合。第二种视锥细胞在415nm处具有最大敏感性，并与一个截止波长低于390nm的油滴相关联。
