NERVOUS SYSTEM AND REFLEXES Introduction:
... The photopupillary reflex enables a rapid adjustment of the size of the pupil of the eye to the existing light intensity. This reflex is coordinated by the brain. The reflex is most easily observed in persons with light-colored eyes. When a bright light stimulates the retina of the eye, impulses are ...
