Question

Quizplus · Accepted Answer

The SCN, or suprachiasmatic nucleus, is a part of the brain that controls the body's circadian rhythms. The expression of genes within the SCN can be influenced by exposure of the eyes to light, as the SCN receives direct input from light-sensitive cells in the retina. Barometric pressure, diet, and morning exercise may have some impact on the body's overall physiology, but they are not known to directly affect the expression of SCN genes.
