In chronic experiments and in acute experiments with nembutal narcosis, photic-driven evoked potentials (EP's) were studied in the superior colliculi (SC) and in the cerebral visual cortex (VC, Area 17). In chronic experiments it was found that the EP's in SC and VC have similar latency periods (LP's) equal, respectively, to 12 +/- 1 and 12 +/- 2 msec (p less than 0.05); refractory periods during application of paired flashes are 50 and 70 msec for SC and VC, respectively. The critical frequencies for imitation of rhythmic flashes in both visual centers also coincide, reaching 20-25/sec. EP's with short LP's, equal to the LP's of evoked potentials in the VC, were found also in the frontal and motor cortex and the hippocampus. The problem regarding telencephalization of the retino-tectal channel of the visual system is discussed.
在慢性实验以及使用戊巴比妥麻醉的急性实验中，研究了上丘（SC）和大脑视觉皮层（VC，17区）的光驱动诱发电位（EP）。在慢性实验中发现，SC和VC中的EP具有相似的潜伏期（LP），分别为12±1毫秒和12±2毫秒（p<0.05）；在施加成对闪光时，SC和VC的不应期分别为50毫秒和70毫秒。两个视觉中枢中模拟节律性闪光的临界频率也一致，达到20-25次/秒。在额叶、运动皮层和海马体中也发现了潜伏期短的EP，其与VC中诱发电位的潜伏期相等。讨论了视觉系统视网膜-顶盖通道的端脑化问题。
