The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Bardet-Biedl syndrome provides clues on obesity, blood pressure

University of Iowa researchers have found a clue about how resistance to the hormone leptin might disrupt the brain signals that tell the body when to stop eating.

Testosterone appears to protect people against eating disorders

Testosterone appears to protect people against eating disorders, providing further evidence that biological factors -- and not just social influences -- are linked to anorexia and bulimia, according to new research findings at Michigan State University.

Tiny RNA molecule found to help create skin's protective barrier

Every minute, 30,000 of our outermost skin cells die so that we can live. When they do, new cells migrate from the inner layer of the skin to the surface of it, where they form a tough protective barrier.

Low testosterone levels linked to depression in older men

Older men with lower free testosterone levels in their blood appear to have higher prevalence of depression, according to a report in the March issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Large-scale study of traumatic brain injury

In a rare, large-scale study of traumatic brain injury (TBI) patients who span the full range of severity from mild to moderate and severe, Canadian researchers have found that the more severe the injury, the greater the loss of brain tissue, particularly white matter.

Genetic variations increase risk of anxiety disorders

Massachusetts General Hospital (MGH) researchers - in collaboration with scientists at the University of California at San Diego and Yale University - have discovered perhaps the strongest evidence yet linking variation in a particular gene with anxiety-related traits.

Working memory defects could explain why some children have problems learning

New research from Britain is suggesting that defects in their working memory may explain the problems some children have with learning.

Depression in older men linked to low testosterone

Australian researchers are suggesting that older men who have lower levels of the male sex hormone testosterone in their blood, may be more prone to depression.

Nanotechnology advances brain cancer detection and therapy

Brain cancer is one of the most aggressive and lethal of malignancies, made even more difficult to treat by the fact that most anticancer drugs have a hard time even getting to the tumors.

Short RNA strand helps exposed skin cells protect body from bacteria, dehydration and even cancer

Every minute, 30,000 of our outermost skin cells die so that we can live.

Mouse model tightly matches pediatric tumor syndrome, will speed drug hunt

Frustrated by the slow pace of new drug development for a condition that causes pediatric brain tumors, a neurologist at Washington University School of Medicine in St. Louis decided to try to fine-tune the animal models used to test new drugs.

Ciliary neurotrophic factor protects nerve cells

Since its discovery as a protein that gets specifically released in response to brain injury, ciliary neurotrophic factor (CNTF) has prompted much interest as a potential therapeutic agent.

Brain differences between women and men

What was once speculation is now being confirmed by scientists: the brains of women and men are different in more ways than one.

New discovery on programmed cell death

Investigators at St. Jude Children's Research Hospital have discovered a dance of proteins that protects certain cells from undergoing apoptosis, also known as programmed cell death. Understanding the fine points of apoptosis is important to researchers seeking ways to control this process.
