在视神经切断后7个月，对成年蝾螈视束和顶盖内再生视网膜纤维的解剖通路和轨迹进行了检查。尽管恢复retinotopic有序的中央连接顶盖内，个别再生的视神经束内的视网膜纤维的路径是非常混乱的;路由错误的视网膜纤维表现出曲折的轨迹在顶盖表面上的方法，其网站的正常神经支配。这些结果表明，具有异常通路和曲折轨迹的再生视网膜纤维可以保持，只要它们与适当的目标接触。
The anatomical pathways and trajectories of regenerating retinal fibers within the optic tract and tectum of adult newts were examined, 7 months after transection of the optic nerve. In spite of restoration of retinotopic ordered central connection within the tectum, the pathways of individual regenerating retinal fibers within the optic tract were greatly disorganized; the misrouted retinal fibers exhibited tortuous trajectories on the tectal surface in approach to their sites of normal innervation. These results suggest that the regenerating retinal fibers with abnormal pathways and tortuous trajectories can be maintained provided they are in contact with appropriate targets.
