An aberrant crossed corticotectal pathway can be generated by removal of one visual cortex and the contralateral superior colliculus from newborn rats. This aberrant crossed corticotectal projection arises from the pyramidal neurons located in layer V of the visual cortex and terminates in a spatially orderly manner in the appropriate laminae of the cortically deafferented contralateral colliculus. Comparable results cannot be reproduced by unilateral collicular lesions alone. The significance of these findings and the possible mechanisms involved in the formation of the aberrant pathway are discussed and compared with the retinotectal system.
通过切除新生大鼠一侧的视皮层和对侧的上丘，可以产生一条异常的交叉皮质顶盖通路。这条异常的交叉皮质顶盖投射起源于位于视皮层V层的锥体细胞，并以空间有序的方式终止于去传入皮质的对侧上丘的相应层中。仅通过单侧丘系损伤无法重现类似结果。讨论了这些发现的意义以及异常通路形成中可能涉及的机制，并与视网膜顶盖系统进行了比较。
