Abstract

Photopic background stimulation elevates scotopic increment thresholds (rod-cone interaction) at moderate background levels when both test and concentric disk-background stimuli enter the same eye (monocular condition) but not when they enter different eyes (dichoptic condition). Only when background levels are made extremely high is there any measurable dichoptic interaction, and this interaction does not resemble that observed monocularly. Rod-cone interaction, as usually studied, is a property of monocular pathways in human vision.

摘要

当测试刺激和同心圆盘背景刺激进入同一只眼睛（单眼条件）时，明视觉背景刺激在中等背景水平下会提高暗视觉增量阈值（视杆-视锥细胞相互作用），但当它们进入不同眼睛（双眼条件）时则不会。只有当背景水平极高时，才会有任何可测量的双眼相互作用，而且这种相互作用与单眼观察到的情况不同。通常所研究的视杆-视锥细胞相互作用是人类视觉中单眼通路的一种特性。
