Cells projecting rostrally from the cat's superior colliculus were identified by antidromic activation from the posterior thalamus. These cells occurred principally in the stratum griseum superficiale and stratum opticum, although some were also encountered in deeper laminae. The rostrally projecting neurons of the superficial laminae formed a heterogeneous group with respect to axonal conduction velocity, receptive field dimensions and special response properties, such as directional and velocity sensitivity. No correlation was detected between receptive field size and estimated axonal conduction velocity in these units. Cells with the smallest receptive fields, were rarely excited antidromically from the thalamus.
通过来自丘脑后部的逆向激活，鉴定出了从猫的上丘向前投射的细胞。这些细胞主要出现在浅层灰质和视层，不过在更深的层中也有一些。浅层中向前投射的神经元在轴突传导速度、感受野大小和特殊反应特性（如方向和速度敏感性）方面形成了一个异质群体。在这些单元中，未检测到感受野大小与估计的轴突传导速度之间的相关性。感受野最小的细胞很少从丘脑被逆向兴奋。
