Treatment could help athletes, women with eating disorders Women with extremely low body fat, including runners and dancers, as well as women with eating disorders, are prone to develop hypothalamic amenorrhea, a condition in which their menstrual periods cease, triggering such serious problems as infertility and osteoporosis. Now, a study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) offers the first definitive proof that a lack of leptin contributes to hypothalamic...

Researchers at UT Southwestern Medical Center have identified a signaling pathway in the brain that's sufficient to induce cellular leptin resistance, a problem that decreases the body's ability to "hear" that it is full and should stop eating. "Leptin resistance is a significant factor, yet the mechanisms that underlie the problem remain unclear," said Dr. Joel Elmquist, professor of internal medicine and pharmacology at UT Southwestern and senior author of the study appearing in the March...

Preventing the vasopressin neurons from swelling, and maintaining their size The anti-diuretic hormone "vasopressin" is released from the brain, and known to work in the kidney, suppressing the diuresis. Here, the Japanese research team led by Professor Yasunobu OKADA, Director-General of National Institute for Physiological Sciences (NIPS), and Ms. Kaori SATO, a graduate student of The Graduate University for Advanced Studies, clarified the novel function of "vasopressin" that works in the...

A Mayo Clinic researcher says the surprising findings suggest the possibility of a novel treatment for obesity A study by researchers at Mayo Clinic's campus in Florida and Washington University School of Medicine adds a new twist to the body of evidence suggesting human obesity is due in part to genetic factors. While studying hormone receptors in laboratory mice, neuroscientists identified a new molecular player responsible for the regulation of appetite and metabolism. In the Jan. 11...

Researchers at the University of Colorado School of Medicine have created a new and exciting mouse model to study how lipid sensing and metabolism in the brain relate to the regulation of energy balance and body weight. The research team, led by Hong Wang, PhD, created mice with a deficiency of lipoprotein lipase (LPL) in neurons, and observed two important reactions. First, the mouse models ate less and second, they became sedentary. Because LPL is important to the delivery of fatty acids to...

UT Southwestern Medical Center researchers have pinpointed a tiny site in the brain where the hormone leptin may help trigger the onset of puberty. The findings in mice indicate that a site within the hypothalamus called the ventral premammillary nucleus, or PMV, is the target where the hormone leptin effectively kick starts puberty in females. Researchers have known that puberty starts when individuals have enough energy stores or fat to meet the demands of reproduction, and that leptin...

The timing of the onset of puberty is linked to levels of nutrition: later onset is associated with malnutrition, while earlier onset is linked to childhood obesity. A team of researchers, led by Carol Elias, at the University of Texas Southwestern Medical Center, Dallas, has now generated data in mice that run counter to current thinking about the molecular pathway by which nutrition status affects the onset of puberty. Further, the team defines a new regulatory pathway for the process,...

New findings by researchers at UT Southwestern Medical Center suggest that serotonin "“ a brain chemical known to help regulate emotion, mood and sleep "“ might also have anti-diabetic properties. The findings, appearing online this week in Nature Neuroscience, also offer a potential explanation for why individuals prescribed certain kinds of anti-psychotic drugs that affect serotonin signaling sometimes have problems with their metabolism, including weight gain and the...

Research conducted by scientists at LSU Health Sciences Center New Orleans has found that two proteins in the brain act as valves to turn the hormone that regulates water retention in the body on and off. Their findings may lead to advances in treatment for diseases like high blood pressure, congestive heart failure, and cirrhosis of the liver. The research is published in the November 1, 2010 issue of Endocrinology. Daniel Kapusta, PhD, Professor of Pharmacology at LSU Health Sciences Center...

(Ivanhoe Newswire) -- Here's a new reason to hit the gym. Besides burning calories, it also makes you think you're fuller. New research shows exercise restores the sensitivity of neurons involved in the control of satiety or feeling full, which in turn contributes to reduced food intake and consequently weight loss. Obesity has been an increasing problem in the world. Just in the U.S, in 2009, only Colorado and the District of Columbia had a prevalence of obesity less than 20 percent....

2013-03-04 13:43:30

The hypothalamus is an organ that serves as an important link, along the hypothalamic-hypophyseal axis, between the nervous system and the endocrine system. It is located within the cranial cavity, in the cerebrum, right below the thalamus. It also forms the floor of the third ventricle in the brain. It contains neural pathways, blood vessels, glial cells, and secretory cells—all of which work together to control things like body temperature, hunger, thirst, sleep, and hormonal and...
