Research deciphers 'déjà -vu' brain mechanics
06-07-2007 · Massachusetts Institute of Technology (MIT)Neuroscientists at the Picower Institute for Learning and Memory report that they have identified a neuronal mechanism that helps us rapidly distinguish similar, yet distinct, places. The discovery helps explain the sensation of déjà vu.

- Research Links Brain Chemistry with Aggressive Personality
06-04-2007 · Brookhaven National Laboratory
An image depicting research findings linking brain chemistry with aggressive personality has been named "2007 Image of the Year" by the Society for Nuclear Medicine. The research, which was performed at Brookhaven Lab, showed that healthy men with lower levels of a particular brain enzyme exhibited more aggressive personality traits, as measured by a standard personality questionnaire.

- Alcohol abuse is in the genes
06-29-2007 · EurekAlert!
Researchers state that "alcohol-abuse prevention must consist of locating and identifying genetically predisposed subjects." The research reveals that a subject's brain with low beta-endorphin levels becomes accustomed to the presence of an exogenous surplus, diminishing its own supply and triggering dependence on an external source -- in this case, alcohol.

- New protein synthesis not essential to memory formation
07-26-2007 · EurekAlert!
New research from the University of Illinois challenges the premise that the brain must build new proteins in response to an experience for that experience to be recorded in long-term memory.The findings, published in the Proceedings of the National Academy of Sciences, could alter basic assumptions about the role of protein synthesis in memory formation.

- 3-D fruit fly images to benefit brain research
09-04-2007 · EurekAlert!
In a paper published on September 5 in the online, open-access journal PLoS ONE, a team led by Mary O'Connell of the MRC Human Genetics Unit describe how they have already used an imaging technique called optical projection tomography (OPT) to image individual cavities within the brain of an aging fly and see the brain deteriorate. The OPT images could help to speed up genetic research into Alzheimer's and other human diseases affecting brain cells.

- New insight into childhood metabolic disease
10-11-2007 · EurekAlert!
Glutaric acidemia type I is an inherited disorder similar to Huntington disease. In most, but not all, affected children, a period of normal development is followed by an irreversible brain injury triggered by a nonspecific illness. New research using a mouse model of GA-I has provided insight into the mechanisms underlying injury and age-dependent susceptibility to the disease and suggested a way to monitor children with the disease.

- Feeling sleepy is all in your genes
10-17-2007 · EurekAlert!
Genes responsible for our 24-hour body clock influence not only the timing of sleep, but also appear to be central to the actual restorative process of sleep, according to research published in the online open access journal BMC Neuroscience. The study identified changes in the brain that lead to the increased desire and need for sleep during time spent awake.

- Obesity research boosted by watching hunger in the brain
11-07-2007 · EurekAlert!
Scientists can now measure how full or hungry a mouse feels, thanks to a new technique which uses imaging to reveal how neurons behave in the part of the brain which regulates appetite. Researchers hope the technique, which uses magnetic resonance imaging, will enable a far greater understanding of why certain people become obese when others do not, and why different people have different appetites.

- Left brain helps hear through the noise
11-14-2007 · EurekAlert!
Our brain is very good at picking up speech even in a noisy room, an adaptation essential for holding a conversation at a cocktail party, and now we are beginning to understand the neural interactions that underlie this ability. An international research team reports today, in the online open-access journal BMC Biology, how investigations using neuroimaging have revealed that the brain's left hemisphere helps discern the signal from the noise.
