Interocular transfer of monocularly learned pattern discriminations was found to be imperfect in split-chiasm cats but to improve as a result of specific practice with interocular transfer tasks. Section of the forebrain commissures subsequently performed in these animals abolished immediate interocular transfer of pattern discriminations. However, there were some savings in reattaining the learning criterion with the second eye. Other cats that learned the same discriminations monocularly but had sustained a combined section of optic chiasm and forebrain commissures before learning showed no indication of interocular transfer. These data suggest that the commissural systems involved in interocular and interhemispheric transfer of pattern discriminations may be modified by practice and learning. Further, it is possible that the intervening transfer experience between the section of the optic chiasm and that of the forebrain commissures results in the persistence of some capacity for interocular transfer of pattern discriminations after commissurotomy. However, this residual capacity may be negligible when compared with the capacity for interocular transfer of split-chiasm cats with intact forebrain commissures.
研究发现，在视交叉切断的猫中，单眼学习的模式辨别在眼间转移并不完美，但通过眼间转移任务的特定训练可以得到改善。随后对这些动物进行前脑连合切断，消除了模式辨别立即发生的眼间转移。然而，在用第二只眼睛重新达到学习标准时存在一些节省。其他单眼学习相同辨别的猫，但在学习前视交叉和前脑连合联合切断，未显示眼间转移迹象。这些数据表明，参与模式辨别眼间和半球间转移的连合系统可能会因训练和学习而改变。此外，视交叉切断和前脑连合切断之间的中间转移经验可能导致连合切断术后模式辨别眼间转移的某种能力持续存在。然而，与前脑连合完整的视交叉切断猫的眼间转移能力相比，这种残余能力可能微不足道。
