When lightstimulus was weaker and concentrated on central vision, there was no significant difference between a red light and a green light in the aspect of dark adaptation.
光刺激作用主要集中在视网膜中央窝的条件下，等亮度较弱的红光与绿光之间暗适应时间无显著差异。

Here we demonstrate by in vivo time-lapse imaging of optic tectal cells in Xenopus laevis tadpoles that enhanced visual activity driven by a lightstimulus promotes dendritic arbor growth.
在此，我们使用视觉非洲爪蟾蝌蚪顶盖细胞活体延时成像证明，轻微刺激下增强的视觉活动促进树突棘生长。

The researchers also tested the flies' saliva for enzymes that signal sleepiness and measured the flies' ability to associate a light with an unpleasant stimulus.
