- UCLA study first to show autistic brains can be trained to recognize visual and vocal cues
06-27-2007 · EurekAlert!
Providing autistic children with explicit instructions to pay more attention to facial expressions and tone of voice elicited an increased response in the medial prefrontal cortex, part of the brain's network for understanding the intentions of others. The findings may have implications for future therapeutic interventions.

- Researchers use novel three-dimensional imaging technique
10-24-2006 · EurekAlert!
Using an innovative three-dimensional imaging technique, a team of UCLA researchers have tracked how Alzheimer's disease spreads through the hippocampus -- the area of the brain linked with memory -- in a pattern consistent with the known trajectory of neurofibrilliary tangle dissemination, an accumulation of diseased proteins in the brain cells. They found that three areas within the hippocampus of Alzheimer's patients show more atrophy compared with those in patients having amnestic mild cognitive impairment.

- 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.

- UCLA imaging study provides clues about inability to imitate and empathize in autistic children
05-04-2007 · EurekAlert!
New imaging research at UCLA shows that impairments in autistic children's ability to imitate and empathize can be linked to dysfunction in the brain’s mirror-neuron system.

- Carnegie Mellon uses new imaging technique to discover differences in brains of people with autism
10-23-2006 · EurekAlert!
Using a new form of brain imaging known as diffusion tensor imaging (DTI), researchers in the Center for Cognitive Brain Imaging at Carnegie Mellon University have discovered that the so-called white matter in the brains of people with autism has lower structural integrity than in the brains of normal individuals. This provides further evidence that the anatomical differences characterizing the brains of people with autism are related to the way those brains process information.

- Sound training rewires dyslexic children's brains for reading
10-30-2007 · EurekAlert!
Brain imaging adds further support to the idea that at least some children with dyslexia have trouble processing sound, rather than a visual problem. The study also shows that computer-based sound training exercises can not only improve reading but literally rewire the brain. The findings may help clinicians detect and remediate dyslexia even before children begin learning to read.

In the first large-scale analysis of proteins in the brains of individuals addicted to cocaine, researchers have uncovered novel proteins and mechanisms that may one day lead to new treatment options to fight addiction.

- 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.

- New imaging technique identifies people-at-risk for Alzheimer's disease
12-20-2006 · EurekAlert!
UCLA researchers used innovative brain scan technology with a new imaging molecule, invented at UCLA, to show that abnormal brain protein deposits that define Alzheimer's disease can be detected in people with mild cognitive impairment, a condition affecting 15-20 million Americans that increases risk for developing Alzheimer's disease. The new imaging technique helped researchers track disease progression over a two-year period and may be helpful in detecting pre-Alzheimer's conditions.
