Free will takes flight: how our brains respond to an approaching menace
08-23-2007 · EurekAlert!Wellcome Trust scientists have identified for the first time how our brain's response changes the closer a threat gets. Using a "Pac Man"-like computer game where a volunteer is pursued by an artificial predator, the researchers showed that the fear response moves from the strategic areas of the brain towards more reactive responses as the artificial predator approaches.

- MRI shows brains respond better to name brands
11-28-2006 · EurekAlert!
Your brain may be determining what car you buy before you've even taken a test drive. A new study gauging the brain's response to product branding has found that strong brands elicit strong activity in our brains. The findings were presented today at the annual meeting of the Radiological Society of North America.

- UCLA: How does your brain respond when you think about gambling or taking risks?
01-25-2007 · EurekAlert!
Should you leave your comfortable job for one that pays better but is less secure? Should you have a surgery that is likely to extend your life but poses some risk you will not survive the operation? In the Jan. 26 issue of the journal Science, UCLA psychologists present the first neuroscience research comparing how our brains evaluate the possibility of gaining versus losing when making risky decisions.

- Brain's impaired ability to sense glucose might play role in type 2 diabetes
08-30-2007 · UT Southwestern Medical Center
New findings from studies in mice suggest that defects in the brain's ability to respond to glucose play a role in the development of non-insulin dependent (type 2) diabetes, and that a high-fat diet may contribute to impairing brain cells' ability to regulate glucose throughout the body.

- Thinking makes it so: Science extends reach of prosthetic arms
11-11-2007 · EurekAlert!
A technique allowing a prosthetic arm to respond directly to brain signals has the potential to provide more arm and hand movements, beyond the four the technique has already achieved, a new study shows. The researchers have begun work with two US Army medical centers to help soldiers who have lost limbs.

- Lipids in the brain an important factor for Alzheimer's disease?
12-10-2007 · EurekAlert!
As the most common form of dementia in the Western world, Alzheimer's disease carries enormous implications for our ageing society. It is generally accepted that the disease is caused by Alzheimer peptide (A -peptide) protofibrils. Until now, the conditions under which this type of protofibril is formed and leads to the disease remained unknown. VIB researchers have now discovered that certain lipids, present also in our brains, promote the formation of this protofibril.

- Chemical signature of manic depression discovered by scientists
02-05-2008 · EurekAlert!
People with manic depression have a distinct chemical signature in their brains, according to a new study. The research, published today in the journal Molecular Psychiatry, may also indicate how the mood stabilisers used to treat the disorder counteract the changes in the brain that it appears to cause.

- MIT researcher: Learning about brains from computers, and vice versa
02-15-2008 · EurekAlert!
For many years, Tomaso Poggio's lab at MIT ran two parallel lines of research. Some projects were aimed at understanding how the brain works, using complex computational models. Others were aimed at improving the abilities of computers to perform tasks that our brains do with ease. But recently Poggio has found that the two tasks have begun to overlap to such a degree, that it's now time to combine the two lines of research.

- Blocking immune cell action increases Alzheimer's-associated protein deposits
03-27-2007 · EurekAlert!
The immune system's response against amyloid-beta, the protein that forms plaques in the brains of patients with Alzheimer's disease, appears to protect the brain from damage in early stages of the devastating neurological disorder. A report from Massachusetts General Hospital researchers finds that lack of a protein required for recruitment of the brain's primary immune cell led to increased amyloid-beta deposits and earlier death in a mouse model of Alzheimer's disease.

- Scientists identify 36 genes, 100 neuropeptides in honey bee brains
10-25-2006 · EurekAlert!
From humans to honey bees, neuropeptides control brain activity and, hence, our behaviors. Understanding the roles these peptides play in the life of a honey bee will assist researchers in understanding the roles they play in their human counterparts.
