本文用小视觉刺激和细尖金属微电极记录聚集单位电反应的方法，研究了大鼠视野与上级丘的地形关系。在对脑曲率进行适当校正后，证明了对侧丘上精确的基本线性投影。视网膜定位投射的一般模式和排列与哺乳动物以下脊椎动物中发现的相似。同侧投影似乎缺失。在静态和运动光刺激下，研究了结肠单个单位的相位特性和节律放电模式。
The topographical relations of the visual field with the superior colliculus of the rat was investigated using constant small visual stimuli and recording the electrical response of aggregate unit activity with fine tip metal microelectrodes. A precise essentially linear projection onto the contralateral colliculus was demonstrated after appropriate corrections for brain curvature were performed. The general pattern and arrangement of the retinotopic projection is similar to that found in infra‐mammalian vertebrates. An ipsilateral projection appears to be absent. The phasic properties and rhythmic discharge patterns of single units in the coliculus were studied with stationary and moving luminous stimuli.
