Behavioral effects of monocularity were assessed in rats, by means of visual discrimination training in a jumping box. The results showed that the experimental subjects did not differ from controls in brightness discrimination, however, were significantly inferior on a conditional discrimination task. This particular test involves the association of present cues with previously learned ones. Since previous work proposes the consideration of the rat's brain as a functional split-brain, and in our condition the visual information was highly lateralized only to the contralateral hemisphere, we suggest that our results may be due to an impairment produced by the reduction of the brain mass available for the discrimination.
通过在跳箱中进行视觉辨别训练，评估了大鼠单眼视觉的行为效应。结果表明，实验对象在亮度辨别方面与对照组没有差异，然而，在条件辨别任务上明显较差。这个特定的测试涉及将当前线索与先前学到的线索联系起来。由于先前的研究提出将大鼠的大脑视为功能性裂脑，并且在我们的实验条件下，视觉信息仅高度偏向对侧半球，我们认为我们的结果可能是由于可用于辨别的脑质量减少而产生的损伤所致。
