Abstract

In the Frog, after unilateral optic nerve and tract section, contralateral visual responses were recorded in the tectum ipsilateral to the section. These responses were elicited by stimulation of a unique spatial region located near the projection of the contralateral eye optic axis and could be randomly recorded on the tectal surface. The possible pathways and the role of such retino-tectal afferences are discussed.

[在正常蛙蛙中存在非视网膜着位的对侧视网膜顶盖视觉投影]。
在蛙的单侧视神经和视束切片后,在该切片的同侧顶盖记录对侧视觉反应。这些反应是通过刺激位于对侧眼视轴投影附近的独特空间区域引起的,并且可以随机记录在顶面上。讨论了这种视网膜-顶叶传入的可能途径和作用。
