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.

Study into whether folic acid and other B vitamins can help slow dementia

The world's largest ever study into a possible link between B vitamins and Alzheimer's disease is to be based at Oxford University.

Iodine could have helped to spare many Chernobyl children from thyroid cancer

As the 20th anniversary of Chernobyl approaches, UNICEF says that the numbers of children who developed thyroid cancer could have been significantly lower if they had been consuming iodized salt in their daily diet at the time of the accident.

Quicker and more effective way to diagnose motor neurone disease

Researchers from University of New South Wales (UNSW), the Prince of Wales Medical Research Institute (POWMRI) and the Prince of Wales Hospital have found a quicker and more effective way to diagnose Motor Neurone Disease (MND).

Map of the human brain sheds new light on dyslexia

Mapping the human brain at The University of Auckland has revealed that abnormal brain activity appears to be the reason why some dyslexia sufferers find it difficult to learn to read.

Breast implants safer than first thought when it comes to breast cancer

According to a new study silicone breast implants do not affect the risk of breast cancer in women who have cosmetic surgery.

New orthostatic hypotension treatment reduces symptoms without causing high blood pressure

A drug traditionally used to treat myasthenia gravis shows potential benefit for reducing symptoms of orthostatic hypotension without raising blood pressure when people lie down, according to results of a double-blind, controlled clinical trial.

Scientists gain greater understanding of how embryos differentiate left from right

Researchers at the Forsyth Institute have discovered a new mechanism responsible for early left/right patterning, the process by which organs locate themselves on the left or right side of the body.

New research shows specific mechanisms may not exist for facial recognition

New research from Georgetown University Medical Center suggests that the brain may not have developed a specific ability for "understanding faces" but instead uses the same kind of pattern recognition techniques to distinguish between people as it uses to search for differences between other groups of objects, such as plants, animals and cars.

Western Australia measles warning

The West Australian Department of Health has issued an alert following notification of five cases of measles in Western Australia over the Easter period.

New tool taps drool for clues to childhood stress

In four separate studies of mothers and their infants, preschoolers, kids and teens, a multi-university research team has shown, for the first time, that a simple test of a little drool can provide new insight into the role of social stressors, including relationships with parents and teachers, in child development.

Study could lead to development of differential treatments for pain in men versus women

A study conducted by investigators at Georgia State University and the Atlanta-based Center for Behavioral Neuroscience (CBN) reports that anatomical and functional differences in the brain may explain sex differences in the experience of pain and in the effects of certain drugs on pain.

Promising treatment for Huntington's disease soon to be tested clinically

At the Institut Curie, CNRS and Inserm researchers have shown that cysteamine, which is already used to treat a rare disease called cystinosis, prevents the death of neurons in Huntington's disease. Like Alzheimer's and Parkinson's, Huntington's disease, is characterized by the abnormal death of neurons.

St. Jude develop strategy to speed future development of more effective and less toxic treatments for medulloblastoma

Investigators at St. Jude Children’s Research Hospital have developed a strategy to speed future development of more effective and less toxic treatments for medulloblastoma, a type of brain cancer. Medulloblastomas arise in the back of the brain and account for about 20 percent of childhood brain tumors.

Breast implants not associated with an increased risk of cancer

Implants were associated with a decrease in breast cancer risk and an increased lung cancer risk, but these results likely reflect the lifestyles and smoking habits of the women in the study rather than an effect of the implants themselves, the authors conclude.

Microarray analysis could lead to better understanding of mechanisms underlying the genetic propensity toward excessive drinking

The meta analysis, which examined more than 4.5 million data points on more than 100 microarrays from mouse models, also identified more than 1,300 functional groups, including signaling and transcription pathways, which may also play an important role in establishing a capacity for a "high level of alcohol consumption."

Brits get serious about drinking and depression

Experts in the UK are warning that the favorite ritual of a glass of wine at the end of a stressful working day is for many a form of "self-medication" and a substitute for seeking professional help with their problems.

It's a vicious circle - exposure to stress causes anxiety and depression

Experts in the United States say the results of a study with mice suggests that stress in itself may cause anxiety and depression.

Sticky proteins for neuro-chip chat

EU-funded researchers have taken the firsts steps towards future technologies combining silicon circuits and the nervous systems of mammals. Applications could include advanced drug screening and, perhaps one day, implants to help combat neurological disorders.

Anxiogenic-like effect of chronic corticosterone in the light-dark emergence task in mice

Neuroscientists at Harvard Medical School and its affiliate McLean Hospital have shown that long-term exposure to stress hormone in mice directly results in the anxiety that often comes with depression.

Hap1 protein could lead to future drug targets for eating disorders

Researchers have discovered how the protein Hap1, which is abundant in the brain's hypothalamus, serves as the link between circulating insulin in the blood and the neural circuitry that controls feeding behavior in mice.
