Quizplus · Accepted Answer

The suprachiasmatic nucleus (SCN) is a region of the brain that is responsible for regulating circadian rhythms, or daily rhythms. Visual input to the SCN, specifically light exposure to the retina, is an important factor in setting and synchronizing these rhythms to the 24-hour day. Therefore, choice A is the best answer. The other answer choices do not accurately describe the role of the SCN in processing visual input.
