Omega-3s boost grey matter, findings may explain why omega-3s seem to improve mood
03-07-2007 · EurekAlert!Omega-3 fatty acids, found in fatty fish like salmon, are associated with increased grey matter volume in areas of the brain commonly linked to mood and behavior according to a University of Pittsburgh study.

- Study finds role of mid-brain in integrating heart and respiratory response to exercise
04-29-2007 · EurekAlert!
Oxford University researchers recently examined several deep brain nuclei during exercise and have concluded that the periaqueductal grey area (PAG), the small-celled gray matter adjoining or surrounding the cerebral aqueduct and the third ventricle in the midbrain, contains the greatest number of neural changes in connection with anticipation of exercise. The findings provide direct evidence implicating the PAG as a key area of the brain's circuitry's affecting cardiorespiratory response to exercise.

- Finding the door to a parallel universe
01-30-2008 · EurekAlert!
If there were a wormhole linking us to a parallel universe, how would we spot it? One suggestion is that it will give itself away by the curious way it bends light. This idea assumes the existence of so called "phantom matter" which has been proposed to explain how a wormhole might stay open. The phantom matter would cause light from another universe, passing through the wormhole, to diverge and emerge as a bright ring.

- Slow reading in dyslexia tied to disorganized brain tracts
12-03-2007 · EurekAlert!
Researchers at Children's Hospital Boston and Beth Israel Deaconess Medical Center have found that difficulty in reading smoothly, or fluently, which occurs in some types of dyslexia, may be caused by disorganized, meandering tracts of nerve fibers in the brain. The findings, which point to organized white matter as the structural basis in the brain for fluent reading, could help specialists find new ways to improve the automatic nature of reading in individuals with dyslexia.

- Bottleneck in blood supply makes brain vulnerable to strokes
01-03-2007 · EurekAlert!
A team of University of California, San Diego physicists and neuroscientists has discovered a bottleneck in the network of blood vessels in the brain that makes it vulnerable to strokes. The finding may explain the origin of the puzzling damage to the brain's gray matter often detected in brain scans, especially among the elderly.

- Ears ringing? Johns Hopkins scientists ID the brain's own clarion
10-31-2007 · EurekAlert!
Brain scientists at Johns Hopkins have discovered how cells in the developing ear make their own noise, long before the ear is able to detect sound around them. The finding, reported in this week's Nature, helps to explain how the developing auditory system generates brain activity in the absence of sound. It also may explain why people sometimes experience tinnitus and hear sounds that seem to come from nowhere.

- Monell researchers find metabolic defect in liver that can lead to obesity
07-24-2007 · EurekAlert!
Researchers at the Monell Center have identified a genetically-transmitted metabolic defect that can lead to obesity. The defect involves decreased production of liver enzymes needed to burn fat and may help to explain why some people become obese while others remain thin. The findings could open the door to the development of new obesity drugs.

- Omega-3 fatty acid may help prevent Alzheimer's brain lesions
04-17-2007 · EurekAlert!
A type of omega-3 fatty acid may slow the growth of two brain lesions that are hallmarks of Alzheimer's disease, UC Irvine scientists have discovered. The finding suggests that diets rich in docosahexaenoic acid (DHA) can help prevent the development of Alzheimer's disease later in life.
