Abstract

Both normal and commissure-sectioned rabbits were examined over a variety of visual discrimination tasks. The visual displays were projected at various distances within the frontal visual field of the rabbit. The learning of either a black-white or a vertical-horizontal problem was found to be normal in commissure-cut animals. Furthermore, no deficit in angular acuity was observed. However, when they were tested with the patterns displayed at 25 cm distance, large impairments were found in the commissure-sectioned animals.

摘要

对正常和胼胝体切断的兔子进行了各种视觉辨别任务的测试。视觉显示器投射在兔子额叶视野内的不同距离处。发现在胼胝体切断的动物中，学习黑白或垂直-水平辨别问题的能力正常。此外，未观察到角分辨力缺陷。然而，当用距离为25厘米处显示的图案对它们进行测试时，发现胼胝体切断的动物有很大的损伤。
