Electrical stimulation of the superior colliculus by square pulses evokes responses in the ipsilateral occipital region whose localization coincides with the zone of evoked potentials to photic stimulation. The short latent period of the visual cortical evoked potentials to stimulation of the superior colliculus (mean 3.2 +/- 1.1 msec; P less than 0.05) together with morphological data suggests that only one relay, in the structures of the thalamus, occurs along the tectocortical pathway in the rat visual system. In the poorly differentiated cortex of the rat no separate representation of retino-geniculo-cortical and tectocortical channels could be found.
通过方形脉冲对上丘进行电刺激，可在同侧枕叶区域诱发反应，其定位与光刺激诱发电位的区域一致。对视皮层诱发电位而言，刺激上丘后的潜伏期较短（平均3.2±1.1毫秒；P<0.05），结合形态学数据表明，在大鼠视觉系统的顶盖皮质通路中，丘脑结构中仅存在一个中继站。在大鼠分化程度较低的皮层中，未发现视网膜-膝状体-皮层通道和顶盖皮质通道的单独表征。
