Abstract

It is widely believed that human rods cannot detect rapid flicker. With rod-isolation techniques, however, light-adapted rods detect flicker frequencies as high as 28 hertz, and the function relating rod critical flicker frequency to stimulus intensity contains two distinct branches. Human rod vision may, therefore, depend on two independent mechanisms.

摘要

人们普遍认为人类的视杆细胞无法检测快速闪烁。然而，采用视杆细胞分离技术时，适应明亮环境的视杆细胞能检测到高达28赫兹的闪烁频率，并且将视杆细胞临界闪烁频率与刺激强度相关联的函数包含两个不同的分支。因此，人类的视杆细胞视觉可能依赖于两种独立的机制。
