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.

Mouse genes guide search for human anxiety disorder genes

We are all familiar with the question - "Are you a man or a mouse?" What if the answer is "a little of both"? Because of the power of molecular genetics research in animals and the maturation of animal models, the path to identifying genes involved in particular types of behavior, such as fear, is much clearer in animals than in humans.

Memory function varies after damage to key area of the brain

Scientists at the University of Liverpool have discovered dramatic differences in the memory performance of patients with damage to the hippocampus, an area of the human brain key to memory.

Leukaemia drug may reverse multiple sclerosis brain damage

Scientists in Britain say a drug which was developed to treat leukaemia may also be a powerful new weapon against multiple sclerosis (MS).

Scientists grow prostates from mouse stem cells

A team of molecular biologists in the U.S. have grown complete prostates derived from stem cells in the prostates of mice and they say the experiment represents a big step towards regenerating organs from a patients' own cells.

New obesity drug Tesofensine may have huge potential

According to trials, a new obesity drug, Tesofensine, which may be launched on the world market in a few years, can produce weight loss twice that of currently approved obesity drugs. The Danish company Neurosearch and a number of researchers at the Faculty of Life Sciences at University of Copenhagen are behind the promising findings.

Depressed pregnant women have twice the risk of preterm delivery

Depressed pregnant women have twice the risk of preterm delivery than pregnant women with no symptoms of depression, according to a new study by the Kaiser Permanente Division of Research. The study is published online in the Oxford University Press's journal Human Reproduction on behalf of the European Society of Human Reproduction and Embryology.

Could brain abnormality predict drug addiction?

Scientists at The University of Nottingham are to use MRI technology to discover whether abnormalities in the decision-making part of the brain could make some people more likely to become addicted to drugs.

Gene study sheds new light on lung cancer

A multi-institution team, funded by the National Human Genome Research Institute (NHGRI) of the National Institutes of Health (NIH), today reported results of the largest effort to date to chart the genetic changes involved in the most common form of lung cancer, lung adenocarcinoma. The findings should help pave the way for more individualized approaches for detecting and treating the nation's leading cause of cancer deaths.

Gene find sheds light on motor neuron diseases like amyotrophic lateral sclerosis

Scientists have identified a gene in mice that plays a central role in the proper development of one of the nerve cells that goes bad in amyotrophic lateral sclerosis, or Lou Gehrig's disease, and some other diseases that affect our motor neurons.

High-dose hormone treatment might reduce risk for posttraumatic stress disorder

Cortisol helps our bodies cope with stress, but what about its effects on the brain? A new study by Cohen and colleagues, appearing in the October 15th issue of Biological Psychiatry, suggests that the answer to this question is complex.

Education and work help beat Alzheimer's

New research has revealed that education and a mentally demanding job protects people from Alzheimer's disease.

Cell phones and brain cancer - major research initiatives needed

Major research initiatives are needed immediately to assess the possibility that using cellular phones may lead to an increased risk of brain tumors, according to an editorial in the November issue of the journal Surgical Neurology, published by Elsevier.

Worries over test for mad cow disease

A new test to screen blood for the incurable human form of mad cow disease could be available within 18 months, but it has raised concerns.

Fatty acids may be the culprit in Alzheimer's

According to new research from the U.S. controlling the level of a fatty acid in the brain could help treat Alzheimer's disease (AD).

Beyond recognizing odors, a single neuron controls reactions

Babies will smile when they catch the scent of vanilla, but a whiff of rotting meat will send them into fits. From people to mice and flies to worms, animals of all kinds are born with likes and dislikes thanks to the evolutionary wisdom collected in their genes. But new research shows that some preferences are still surprisingly flexible at even the most basic level - that of the sensory neuron itself - and that our nervous system may be even more adaptable than we thought.

New hope for a better treatment for childhood cancer

Children who are diagnosed with cancer could benefit from better diagnosis and treatment in the future thanks to a new research project involving clinicians and scientists at The University of Nottingham.

Genes that control cell death may play role in age-related hearing loss

Several genes that play a role in how our body's cells normally auto-destruct may play a role in age-related hearing loss, according to research published online in the journal Apoptosis - a journal devoted to the topic of cell suicide, or programmed cell death.

People with autism less influenced by gut instincts

People with autism-related disorders are less likely to make irrational decisions, and are less influenced by gut instincts, according to research funded by the Wellcome Trust. The study adds to the growing body of research implicating altered emotional processing in autism.
