用金属微电极记录视顶盖的电反应，以小光刺激视顶盖，研究了鲈鱼、鲤鱼、蓝鳃鱼和金鱼4种淡水鱼的视顶盖与视野的地形关系。结果显示，对侧顶盖上有一个精确组织的视觉投射，其中前视野位于顶盖的前部，颞视野位于顶盖的后部，背视野位于顶盖的中背侧，腹视野位于顶盖的侧腹侧。投影被发现基本上是线性和均匀的，没有迹象表明在这些物种的视野中的专门领域。部分感受野延伸至双眼前方视野。
In four species of freshwater fish, bass, carp, bluegill and goldfish, the topographical relations of the visual field with the contralateral optic tectum were investigated, using a small light as stimulus in the visual field and recording the electrical response of the tectum with a metal microelectrode. The results show a precisely organized visual projection onto the contralateral tectum in which the anterior visual field lies anteriorly on the tectum, the temporal field posteriorly, the dorsal field medio‐dorsally, and the ventral field in the latero‐ventral part of the tectum. The projection was found to be essentially linear and uniform with no indication of a specialized area in the visual field in those species investigated. Some receptive fields extended into the anterior binocular visual field.
