## Abstract The effect on the somatosensory evoked response (SER) of the level of anesthesia, and the effect of the site, intensity, duration, and frequency of the stimulus on the amplitude and latency of various components of the SER were studied in 8 Rhesus monkeys. Peroneal nerve stimulation pro
Thymoxamine constricts the pupil without significant effect on accommodation and was used in this study because of the extreme sensitivity of the pattern electroretinogram (PERG) to defocus at high spatial frequencies. Pilocarpine, used in previous studies, can cause an unpredictable spasm of accomm
