The pineal gland, also known as the pineal body, epiphysis cerebri, or conarium, is an endocrine gland in the vertebrate brain about the size of a grain of rice. It is shaped like a tiny pine cone (hence its name), and it’s located in the center of the brain behind and above the pituitary gland. Mystics consider this gland to be the third eye and the connecting link between the physical and spiritual worlds, but until recently the medical community considered it vestigial (an organ that has become functionless through evolution). Now the medical community knows the pineal gland is our major source of melatonin production.
