Separating the brain's 'bad' from 'good' iron
08-23-2007 · EurekAlert!Duke University chemists are developing ways to bind up iron in the brain to combat the neurological devastation of Parkinson's and Alzheimer's diseases. The key is to weed out potentially destructive forms of iron that generate harmful free radicals while leaving benign forms of iron alone to carry out vital functions in the body.

- How the brain handles surprise, good and bad
09-19-2007 · EurekAlert!
Whether it's a mugger or a friend who jumps out of the bushes, you're still surprised. But your response -- to flee or to hug -- must be very different. Now, researchers have begun to distinguish the circuitry in the brain's emotion center that processes surprise from the circuitry that processes the aversive or reward "valence" of a stimulus.

- Why bad things can happen to the heart when 'good' cholesterol goes bad
08-22-2007 · EurekAlert!
It's yet another example of how a good thing can go bad: Researchers have found evidence in laboratory studies that "good" cholesterol, renowned for its ability to protect against heart disease, can undergo detrimental changes in protein composition that make it "bad" for the heart. The study could lead to new lab tests and treatments for heart disease, they say. It will be presented in August at the American Chemical Society national meeting in Boston.

10-25-2006 · EurekAlert!
In the long run, a drink or two a day may be good for the brain. Researchers found that moderate amounts of alcohol -- amounts equivalent to a couple of drinks a day for a human -- improved the memories of laboratory rats. Such a finding may have implications for serious neurodegenerative diseases like Alzheimer's.

People with epilepsy who experience multiple auras, sensations such as a cold breeze or bright light before they have a seizure, may be good candidates for epilepsy surgery because their seizures seem to be coming from one area of the brain, according to a study published in the Aug. 21, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

- Having right timing 'connections' in brain is key to overcoming dyslexia
09-04-2007 · EurekAlert!
Using new software developed to investigate how the brains of dyslexic children are organized, University of Washington researchers have found that key areas for language and working memory involved in reading are connected differently in dyslexics than in children who are good readers and spellers. However, a three-week instructional program can normalize those connections.

In the first neural investigation into what happens to our emotional stability when we lose sleep, researchers from UC Berkeley and Harvard Medical School have found that while a good night's rest can regulate our mood and help us cope with the next day's emotional challenges, sleep deprivation excessively boosts the part of the brain most closely connected to depression, anxiety and other psychiatric disorders.

12-13-2006 · EurekAlert!
There's good news for children growing up in bad neighborhoods in a comprehensive, 8-year study led by University of Colorado at Boulder. The successful development of children in Denver and Chicago from the best neighborhoods was 63 percent, while the success rate for children living in high-poverty, disadvantaged neighborhoods was still relatively high, at 52 percent.

- First of its kind report on how children with brain tumors perform at school
07-16-2007 · EurekAlert!
While children who have had brain tumors perform worse in school than healthy kids, grades in foreign language are the most affected and girls have a harder time than boys in getting good grades, according to a study published in the July 17, 2007, issue of Neurology, the medical journal of the American Academy of Neurology. Researchers say this is the first time the actual grades and subjects of brain tumor survivors have been reported.
