Pineal gland secretes the hormone melatonin at night with a circadian rhythm. The synthesis and secretion of melatonin are stimulated at night by norepinephrine released by sympathetic postganglionic neurons projecting from the superior cervical ganglia.

Timekeeping by the Pineal Gland
Science, 1977N Acetyltransferase, an enzyme involved in melatonin production in the pineal gland, exhibits a circadian rhythm in chickens with peak values in the dark-time and low values during the light-time, commencing at lights-on.

Metastases to the pineal gland
Neurology, 2006We identified 10 patients with symptomatic metastases to the pineal gland. We present the clinical and radiographic findings in this syndrome. Leptomeningeal metastases occur frequently and are a poor prognostic factor. In all cases, the primary cancer was clinically silent, either in remission (six cases) or previously undiagnosed (four cases). Hence,

The pineal gland and aldosterone
American Journal of Physiology-Legacy Content, 1960It has recently been suggested that the canine pineal gland secretes a hormone which stimulates the adrenal cortex to release aldosterone. The following experiments were undertaken to determine what effect pinealectomy or administration of bovine pineal extracts has on certain physiologic variables associated with aldosterone activity in rats: a) the ...

The activity of ornithine decarboxylase was assayed in several organs (thymus, testes, prostate gland, liver, kidneys, adenohypophysis, anterior hypothalamus, and adrenals) taken from adult male rats killed at seven day interval up to six weeks after pinealectomy.

The Pharmacology of the Pineal Gland
Annual Review of Pharmacology and Toxicology, 1976Only recently have a sufficient number of publications been available to legitimize a review of the pharmacology of the mammalian pineal organ. Two decades ago Kitay & Altschule reviewed the world literature on pineal physiology, which comprises several thousand papers, and concluded only that removal of the pineal, or administration of pineal extracts,

Neonatal Network, 2000
The pineal gland is located posterior to the midbrain and is the site of melatonin production. Research on pineal gland function in neonates is very limited. This article will discuss pineal gland development and the possible relationship between melatonin production and sudden infant death syndrome.

Chronobiology International, 2006
The pineal gland plays a key role in the control of the daily and seasonal rhythms in most vertebrate species. In mammals, rhythmic melatonin (MT) release from the pineal gland is controlled by the suprachiasmatic nucleus via the sympathetic nervous system.
