Which outcome occurs when melanopsin-containing retinal ganglion cells are stimulated by light during daytime?

💡 Explanation

The suprachiasmatic nucleus (SCN) synchronizes the circadian rhythm with the external environment through light detection by melanopsin. This entrainment process allows the SCN to coordinate bodily functions with the day-night cycle because light exposure inhibits melatonin production. Therefore, stimulating these cells results in circadian rhythm synchronization, rather than an immediate change in body temperature or enzyme production.
