In cats with midpontine pretrigeminal transections, orientation reflexes to visual stimuli consist only of vertical eye movements, pupillary dilation, and electroencephalographic arousal. Extinction of the orientation reflex by repetition of the photic stimulus is easily obtained; the reflex partially recovers after a few minutes of rest. By using as reinforcement stimulation of hypothalamus producing pupillary dilation and EEG arousal, conditioned responses to a visual stimulus may be obtained. The cat with midpontine pretrigeminal transection can be used as convenient preparation for the study of the orientation and conditioned reflexes.
在中脑桥脑三叉神经前横断的猫中，对视觉刺激的定向反射仅包括垂直眼球运动、瞳孔扩张和脑电图觉醒。通过重复光刺激很容易使定向反射消退；休息几分钟后，反射会部分恢复。通过使用刺激下丘脑产生瞳孔扩张和脑电图觉醒作为强化手段，可以获得对视觉刺激的条件反应。中脑桥脑三叉神经前横断的猫可作为研究定向反射和条件反射的便利实验对象。
