Abstract

The rhythm in melatonin production by the mammalian pineal gland is generated by the circadian timing system. The components of that system which mediate the function are: (1) visual projections through the retinohypothalamic tract to the circadian pacemaker, the suprachiasmatic nucleus (SCN) of the hypothalamus; (2) the SCN which generates a circadian signal transmitted by SCN projections to the parvocellular autonomic component of the paraventricular nucleus; (3) paraventricular nucleus projections to the upper thoracic intermediolateral cell column; (4) preganglionic sympathetic fibers to the superior cervical ganglion; (5) postganglionic sympathetic fibers from the superior cervical ganglion to the pineal.
