MIT shows how brain interprets surfaces
04-19-2007 · Massachusetts Institute of Technology (MIT)A team of researchers from MIT and NTT Lab in Japan reveal how the brain responds to surface textures. Their findings show that the perception of reflectance and gloss may be coded by neurons that respond differentially to light and dark spots.

- MIT model helps researchers 'see' brain development
04-09-2007 · EurekAlert!
Large mammals -- humans, monkeys and even cats -- have brains with a somewhat mysterious feature: the outermost layer has a folded surface. Understanding the functional significance of these folds is one of the big open questions in neuroscience. Now a team led by MIT, Massachusetts General Hospital and Harvard Medical School researchers has developed a tool that could aid such studies by helping researchers "see" how those folds develop and decay in the cerebral cortex.

- New neuroimaging study identifies 'brain signature' for cigarette cravings
12-18-2007 · EurekAlert!
A new brain imaging study by researchers in the Abramson Cancer Center of the University of Pennsylvania shows that cigarette cravings in smokers who are deprived of nicotine are linked with increased activation in specific regions of the brain. Using a novel method of measuring brain blood flow developed at Penn, this study is the first to show how abstinence from nicotine produces brain activation patterns that relate to urges to smoke.

- Carnegie Mellon University research shows how sensory-deprived brain compensates
04-17-2007 · EurekAlert!
Whiskers provide a mouse with essential information. These stiff hairs relay sensory input to the brain, which shapes neuronal activity. In a first, studies of this system by Carnegie Mellon scientists show just how well a mouse brain can compensate when limited to sensing the world through one whisker. Published April 4 in the Journal of Neuroscience, the results should help shape future studies of sensory deprivation that results from stroke or traumatic brain injury.

- Adult brain can change, study confirms
09-05-2007 · Massachusetts Institute of Technology (MIT)
Neuroscientists from MIT and Johns Hopkins University have used evidence from brain imaging and behavioral studies to show that the adult visual cortex reorganizes--and that the change affects visual perception.

- 3 proteins may play important role in nerve-cell repair
04-11-2007 · EurekAlert!
Some mature brain cells can grow new extensions when the amount of three particular proteins on their surface increases, a new study shows. The research examined three related receptor proteins, called GPR3, GPR6 and GPR12, on nerve cells in the brains of rats.

- Bisexual fruit flies show new role for neurochemical
01-02-2007 · EurekAlert!
Fruit flies' ability to discern one sex from another may depend on the number of receptors on the surface of nerve cells, and the number of receptors is controlled by levels of a ubiquitous brain chemical, University of Illinois at Chicago researchers have found.

- Blood-flow detector software show promise in preventing brain damage
08-31-2007 · EurekAlert!
Researchers from the Johns Hopkins Children's Center and Cambridge University in England have designed an automated means of continuously tracking potentially dangerous changes in blood flow to the brain in real time, a system that shows promise for preventing brain damage and death in children with head injuries.

- It's only a game of chance
03-27-2007 · EurekAlert!
Cells in the central nervous system tend to communicate with each other via a wave of electrical signals that travel along neurons. The question is: How does the brain translate this information to allow us to perceive and understand the world? It was believed that these signals generated patterns that the brain could interpret; however, new research shows that such patterns may be random. These studies will contribute to the ongoing debate on neuronal coding.

- A molecule that protects from neuronal disorders
09-14-2007 · EurekAlert!
Researchers from the Mouse Biology Unit of the European Molecular Biology Laboratory in Italy, have now discovered that a protein that helps organising the cells' skeleton is crucial for preventing mental retardation and other neuronal disorders. In the current issue of Genes & Development they report that mice lacking the protein show symptoms of lissencephaly brought about by faulty development of the cerebral cortex, the brain's surface layer.
