The hypothalamus and reproduction
American Journal of Obstetrics and Gynecology, 1972Abstract This article has been designed to review recent developments in the field of hypothalamic hormones involved in the control of reproductive functions. A brief resume of early physiologic and anatomic studies was presented initially to give a better understanding of the concept of hypothalamic regulation of the release of gonadotropic hormones ...

The hypothalamus forms part of the central autonomic network, regulating body homeostasis and controlling pain. To this effect, it is strongly wired to more rostral and caudal areas, in particular the brainstem periaqueductal grey, the locus coeruleus and the median raphe nuclei, all involved in autonomic and sleep mechanisms and also in the descending

The effect of a transitory increase in plasma FSH and LH levels during the prepubertal period on puberty has been investigated. Twenty-day-old rats had been bilaterally ovariectomized and 24 hr later they received two ovaries of infantile rats beneath the kidney capsule. These rats exhibited precocious puberty. Animals into which two additional ovaries

The Hypothalamus and Hypertension
Physiological Reviews, 2001Most forms of hypertension are associated with a wide variety of functional changes in the hypothalamus. Alterations in the following substances are discussed: catecholamines, acetylcholine, angiotensin II, natriuretic peptides, vasopressin, nitric oxide, serotonin, GABA, ouabain, neuropeptide Y, opioids, bradykinin, thyrotropin-releasing factor ...

Optometry - Journal of the American Optometric Association, 2010
For nearly 2 millennia, signs of hypothalamic-related vision disorders have been noticed as illustrated by paintings and drawings of that time of undiagnosed Horner's syndrome. It was not until the 1800s, however, that specific connections between the hypothalamus and the vision system were discovered. With a fuller elaboration of the autonomic nervous

EXPERIMENTS with an analogue model of the heart, demonstrated by me1, show that a pulse may arise, in a fluid-filled elastic system, in either of two ways : in the first, energy is cycled into the system from a mechanical source, corresponding to the physico-chemical contraction of the ventricles ; in the second, pulsation can be derived from the ...

EVIDENCE has recently been produced that, in the rat, oxytocin is synthesized in the paraventricular nucleus1. After small electrolytic lesions in this region a decrease in the amount of oxytocin was found in the posterior pituitary with no change in its vaso-pressin content.

The Hormones of the Hypothalamus
Scientific American, 1972The isolation and synthesis of thyroid stimulating hormone-releasing factor (TRF or TSH-RF) and luteinizing hormone releasing factor (LH-RF) are discussed. Hypothalamic fragments of sheep brains were the source f rom which 1 mg of TRF was first extracted characterized and synthesize d.

The brain is considered a major site for microRNA (miRNA) expression; as evidenced by several studies reporting microarray data of different brain substructures. The hypothalamus is among the brain regions that plays a crucial role in integrating signals from other brain nuclei as well as environmental, hormonal, metabolic and neuronal signals from the

THE HYPOTHALAMUS AND LACTATION
British Medical Bulletin, 1966Various hypothalamic mechanisms are of importance to lactation. Foo d intake increases in lactation to meet the demand for raw materials in milk presumably at the direction of the appetite-controlling mechanisms in the hypothalamus. The direct astimulation of hypothalamic appetite centers may result from the suckling stimulus. Although the ascending
