训练鸽子单眼完成强度、颜色和图案任务。训练结束后，在圆核或丘脑视主核(OPT)进行单侧电解损毁。一半受试者在受过训练的大脑半球(受过训练的眼睛的对侧)造成损伤，另一半受试者在未受过训练的大脑半球造成损伤。在7天的恢复期后，这些鸟儿被重新训练，用以前没有训练过的眼睛完成同样的任务。两侧的圆形损伤导致眼间辨别能力的丧失，而对侧或同侧的OPT损伤都不影响辨别能力。这些结果表明，顶盖分离视觉通路在鸽子大脑半球间视觉信息传递中起重要作用。
Pigeons were trained to perform intensity, color and pattern tasks monocularly. After their training was completed, a unilateral electrolytic lesion was made either in the nucleus rotundus or in the nucleus opticus principalis thalami (OPT). The lesion was made in the trained hemisphere (contralateral to the trained eye) in half of the subjects and in the untrained hemisphere in the other half. After a 7-day recovery period the birds were retrained on the same tasks with the previously untrained eye. A rotundal lesion, on either side, resulted in the loss of interocular transfer of discrimination, whereas neither contralateral nor ipsilateral OPT lesions affected discrimination. These results suggest that the tectofugal visual pathway plays a crucial role in the interhemispheric transfer of visual information in pigeons.
