Question

Quizplus · Accepted Answer

George Wald and Ragnar Granit were the scientists who found three types of cones in the retina, which earned them the Nobel Prize in Physiology or Medicine in 1967. Although Brown and Smith also made significant contributions to the study of color vision, they did not discover the three types of cones. Similarly, Young and Helmholtz proposed the trichromatic theory of color vision but did not directly discover the three types of cones. Hering proposed an opponent process theory of color vision, which is different from the trichromatic theory.
