Question

Quizplus · Accepted Answer

Rods and cones are responsible for detecting light and transmitting information to the brain via the optic nerve, but they do not directly affect melatonin levels. The retinohypothalamic tract and ganglion cells are involved in transmitting light information to the suprachiasmatic nucleus (SCN), which is responsible for regulating melatonin secretion. However, because individuals who are blind still have functioning rods and cones, they may still detect changes in light and be able to entrain to a light-dark cycle.
