Assignment:

With normal lighting, have the volunteer look into the distance and then at an object held about 10 cm from the eye. What happens to pupil diameter when the eye is focused for near vision? Was the sympathetic or parasympathetic division of the ANS active during the testing of these reflexes? While observing the subject's eyes, gently stroke the skin (or just the hairs) on the left side of the back of the subject's neck, close to the hairline. This should initiate the ciliospinal (pupillary-skin) reflex. What is the reaction of the left pupil? Of the right pupil?
