  1. The pineal gland (also called the pineal body or epiphysis) is a small endocrine gland in the brain. It is located near the center of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join. A recent review of the pineal and its secreted hormone, melatonin.
    The pineal gland is responsible for the production of melatonin, which is regulated in a circadian rhythm. Melatonin is a derivative of the amino acid tryptophan. The production of melatonin by the pineal gland is stimulated by darkness and inhibited by light. The retina detects the light, and directly signals and entrains the suprachiasmatic nucleus (SCN). Fibers project from the SCN to the paraventricular nuclei (PVN), which relay the circadian signals to the spinal cord and out via the sympathetic system to superior cervical ganglia (SCG), and from there into the pineal gland.
    The pineal gland is large in children, but shrinks at puberty. It appears to play a major role in sexual development, hibernation in animals, metabolism, and seasonal breeding. The abundant melatonin levels in children is believed to inhibit sexual development. When puberty arrives, melatonin production is reduced.

  2. the pineal gland is located between and a little below the frontal lobes (temporal lobe area) and really, science doesn’t recognize that it HAS a specific purpose. but based on relative data obtained in corresponding brain activity studies, it is probable that the pineal gland is at least partly responsible for our sense of intuition, and affects dream states. some oriental and india-peoples believe that this is the ‘third-eye’ region, the sacred chakra which gives us e s p and other psychic gifts. they call it the ‘seat of the soul’. i suggest you search the net and see if you can find any other facts about this……
