The pineal gland (also called the pineal body , epiphysis cerebri , epiphysis , conarium or the " third eye ") is a small endocrine gland in the vertebrate brain . It produces the serotonin derivative melatonin , a hormone that affects the modulation of wake/sleep patterns and seasonal functions. [ 1 ] [ 2 ] Its shape resembles a tiny pine cone (hence its name), and it is located near the centre of the brain, between the two hemispheres , tucked in a groove where the two rounded thalamic bodies join. [ edit ] Location The pineal gland is reddish-gray and about the size of a grain of rice (5–8 mm) in humans, located just rostro-dorsal to the superior colliculus and behind and beneath the stria medullaris , between the laterally positioned thalamic bodies .
