WebThe afferent pathway sends messages from the pupil to the brain along the optic nerve to the optic tracts, and the efferent pathway sends the message back from the brain to the pupil via nerves, resulting in pupil constriction and dilation. When the pathway is disrupted in one of the eyes, the Marcus Gunn pupil is observed. http://www.uhwi.org/Rapd.html
