The Hypothalamus is the area of the brain that controls body temperature, hunger, and thirst.

Scientists identify brain circuits that 'decide' how much we eat

Scientists have identified the brain circuits that 'decide' how much we eat. Using live brain scanning techniques and an innovative study design, researchers have discovered how the brain controls food intake in humans. Their findings are published in Nature.

Low birth weight children may be at a greater risk of stress-related health problems as adults

Findings from this study show that low birth weight (below the 10th percentile) can lead later in life to low concentrations of cortisol, a hormone that regulates stress response by adjusting blood pressure and blood sugar levels.

Functional brain imaging shows neural circuits contributing to pedophilia

Pedophilia, the sexual attraction of adults to children, is a significant public health concern and it does not respond well to treatment.

Sildenafil increases release of key reproductive hormone oxytocin

Researchers at the University of Wisconsin-Madison report this month that sildenafil increases the amount of oxytocin released by stimulation of the posterior pituitary gland, a small structure directly underneath the brain that regulates hormone levels in response to neural signals.

How the brain produces fever responses during infections

With the finding that fever is produced by the action of a hormone on a specific site in the brain, scientists have answered a key question as to how this adaptive function helps to protect the body during bacterial infection and other types of illness.

Potential dangers of Ritalin

Use of the attention deficit/hyperactivity disorder (ADHD) drug Ritalin by young children may cause long-term changes in the developing brain, suggests a new study of very young rats by a research team at Weill Cornell Medical College in New York City.

Chemical in brain acts like a fuel gauge

The concept that a drop in blood sugar triggers a craving for food is best understood just before lunchtime. But exactly how the process unfolds has proven difficult to explain, even on a full stomach.

Pure oxygen harms the brain

A paramedic or doctor plops a mask over the face of a person struggling to breathe and begins dispensing pure oxygen.

Scientists discover important step in cortisol production

When a person's under stress or injured, the adrenal gland releases cortisol to help restore the body's functions to normal.

Drug resistant headache pain eased by brain stimulation

Researchers in Britain and the United States have found that the extreme pain of cluster headaches can be eased by electrodes.

Research suggests a significant circadian rhythm in swim performance lasting 2-4 minutes

A new study investigating the potential of a circadian rhythm in athletic performance adds further confirmation that it exists. The finding is being published in the Journal of Applied Physiology, one of 11 peer reviewed scientific publications issued monthly by the American Physiological Society (APS).

SH2B1 protein plays a key role in controlling body weight, response to insulin and leptin

A single protein in brain cells may act as a linchpin in the body's weight-regulating system, playing a key role in the flurry of signals that govern fat storage, sugar use, energy balance and weight, University of Michigan Medical School researchers report.

A central thermogenic-like mechanism in feeding regulation

During periods of fasting, brain cells responsible for stimulating the appetite make sure that you stay hungry.

Research offers hope for alcoholics

Scientists at Melbourne's Howard Florey Institute have discovered a system in the brain that stops an alcoholic's craving for alcohol, as well as prevent relapse once they have recovered from alcohol addiction.

Stay cool and live longer!

If new research is to be believed living longer may simply be a case of staying cool.

Newly discovered molecule could lead to new treatments for obesity

Japanese scientists have found a molecule which is responsible for making mammals feel full, and they believe the discovery could lead to new ways to treat obesity in humans.

Food like an addictive drug for some people

Researchers in the U.S. have found that the same brain circuits are involved when obese people fill their stomachs as when drug addicts think about drugs and the discovery they say suggests an association between overeating and addiction.

Insulin receptor stops progression of Alzheimer's disease

Stimulation of a receptor in the brain that controls insulin responses has been shown to halt or diminish the neurodegeneration of Alzheimer's disease, providing evidence that the disease can be treated in its early stages, according to a study by researchers at Rhode Island Hospital and Brown Medical School.

Leptin could combat type 2 diabetes

University of Florida researchers have discovered the appetite-controlling hormone leptin could also combat type 2 diabetes, a disease that has become a growing problem in the United States as more Americans pack on extra pounds.
