Answer: pineal gland
Rationale: The SCN communicates signals about light levels with the pineal gland. The pineal gland releases a hormone called melatonin, which peaks at nighttime and is reduced during wakefulness. Thanks to this system, light is the primary stimulus regulating our circadian rhythm and it tells us to sleep at night and stay awake for the day.
