检查了树鼩中由麦芽凝集素-辣根过氧化物酶（HRP）缀合物的顺行运输标记的同侧视网膜小球投影。对于那些证实了该通路的动物（14 只动物中的 4 只），同侧丘状标记延伸到丘前部的三分之二左右，但最远端除外。在浅层灰色浅层中，标记总是断断续续地以规则的间隔间隔开。讨论了同侧投影的层状分布和斑片状终止，这与起源于颞部视网膜的两条明显独立的通路（交叉和非交叉的丘状通路）有关。
Ipsilateral retinocollicular projections labeled by anterograde transport of wheatgerm agglutinin-horseradish peroxidase (HRP) conjugate in the tree shrew were examined. For those animals in which this pathway was demonstrated (4 of 14) ipsilateral collicular labeling extended across approximately the anterior two-thrids of the colliculus, with the exception of the extreme rostral pole. Labeling was invariably punctuate and spaced at regular intervals in the lower stratum griseum superficiale. The laminar distribution and patchy terminations of ipsilateral projections are discussed in relation to two apparently independent pathways originating in the temoral retina, the crossed and uncrossed collicular pathways.
