The pineal gland is still a somewhat mysterious organ at the center of the brain. It was dubbed the “seat of the soul” by 17th-century French philosopher René Descartes and is still viewed as the physiological structure corresponding to the “third eye” in some esoteric traditions.

In medicine, the pineal gland remains rather elusive to research due to its location, snugly nudged to the wall of the third ventricle in the middle of the brain. Its main and most well-researched function is the secretion of melatonin, a hormone that plays a critical role in regulating the circadian rhythm.
