Some aspects of the pineal gland function

ABSTRACT

Rhythmic production of melatonin by the mammalian pineal gland occurs in response to noradrenergic stimulation which produces a cascade of biochemical events within the pinealocyte. Melatonin is involved in a wide range of physiological processes, including seasonal reproduction and diurnal activity rhythms. It was recently discovered that melatonin is a very potent hydroxyl radical scavenger, reinforcing its relationship with the aging process and the immune system.
