Pupillary responses evoked by electrical stimulation of the area pretectalis and neighboring midbrain structures were studied in the cat. The pupillary responses evoked were recorded using an infrared pupilloanalyzing system. Bilateral pupillary constriction was evoked with a low threshold current intensity by stimulation of the nucleus pretectalis medialis, nucleus pretectalis olivaris, rostral part of the nucleus pretectalis posterior, the most rostral part of the periaqueductal grey and the nucleus of posterior commissure. Bilateral pupillary dilation was induced with a low threshold current intensity by stimulating the nucleus pretectalis anterior, caudal periaqueductal grey and the midbrain tegmentum. The effects of changing stimulus intensity and stimulus frequency were also studied.
在猫身上研究了电刺激顶盖前区和邻近中脑结构所诱发的瞳孔反应。使用红外瞳孔分析系统记录诱发的瞳孔反应。通过刺激内侧顶盖前核、橄榄顶盖前核、顶盖前核后部的嘴侧部分、导水管周围灰质最嘴侧部分和后连合核，以低阈值电流强度诱发双侧瞳孔收缩。通过刺激顶盖前核前部、导水管周围灰质尾部和中脑被盖，以低阈值电流强度诱发双侧瞳孔扩张。还研究了改变刺激强度和刺激频率的影响。
