EAST LANSING, Mich. --- Scientists have discovered a molecular process in the brain triggered by cocaine use that could provide a target for treatments to prevent or reverse addiction to the drug.
Reporting in the Journal of Neuroscience, Michigan State University neuroscientist A.J. Robison and colleagues say cocaine alters the nucleus accumbens, the brain's pleasure center that responds to stimuli such as food, sex and drugs.
West Orange, NJ. March 15, 2013. Kessler Foundation scientists and their colleagues will discuss their progress in rehabilitation research at the upcoming 65th Annual American Academy of Neurology Conference at the San Diego Convention Center in San Diego, CA, March 16 – 23.
BUFFALO, N.Y. – The first controlled clinical trial to test the safety and efficacy of interventional endovascular therapy on the symptoms and progression of multiple sclerosis has found that the intervention, sometimes called the "liberation treatment," which has attracted intense interest in the global MS community, does not improve patient outcomes. In a few cases, the treatment made symptoms worse.
Low and moderate drinkers of alcohol reported lower severity of symptoms of fibromyalgia than teetotallers, finds a study in BioMed Central's open access journal Arthritis Research & Therapy. Too much alcohol reversed this effect.
The chronic pain of fibromyalgia is thought to affect one in 20 people worldwide but there is no known cause or cure. It often goes hand in hand with fatigue and sleep problems, headaches, depression and irritable bowel and bladder problems. Treatment is based around pain management and lifestyle changes.
Researchers in the UK have taken an important step towards understanding how the human brain 'decodes' letters on a page to read a word. The work, funded by the Economic and Social Research Council (ESRC), will help psychologists unravel the subtle thinking mechanisms involved in reading, and could provide solutions for helping people who find it difficult to read, for example in conditions such as dyslexia.
Green tea and coffee may help lower your risk of having a stroke, especially when both are a regular part of your diet, according to research published in Stroke: Journal of the American Heart Association.
Mindfulness — paying attention to one's current experience in a non-judgmental way — might help us to learn more about our own personalities, according to a new article published in the March 2013 issue of Perspectives on Psychological Science, a journal of the Association for Psychological Science.
Researchers at the University of Toronto have shown that playing shooting or driving videogames, even for a relatively short time, improves the ability to search for a target hidden among irrelevant distractions in complex scenes.
"Recent studies in different labs, including here at the University of Toronto, have shown that playing first-person shooter videogames can enhance other aspects of visual attention," says psychology professor Ian Spence. "But no one has previously demonstrated that visual search is also improved."
The brain's prefrontal cortex is thought to be the seat of cognitive control, working as a kind of filter that keeps irrelevant thoughts, perceptions and memories from interfering with a task at hand.
Now, researchers at the University of Pennsylvania have shown that inhibiting this filter can boost performance for tasks in which unfiltered, creative thoughts present an advantage.
Autism Speaks, the autism advocacy organization, today announced a study supported by one of Autism Speaks' first Suzanne and Bob Wright Trailblazer Awards, which presents a new theory that autism may result from chronic danger signaling by mitochondria, cell structures that supply our cells with energy. This study by Trailblazer researcher and mitochondrial medicine specialist Robert Naviaux, M.D., Ph.D., of the University of California, San Diego published in PLOS-ONE supports a novel theory about the cause and potential treatment of autism.
For the first time, a UCLA team has used a technique normally employed in treating brain aneurysms to treat severe, life-threatening irregular heart rhythms in two patients.
This unique use of the method helped stop ventricular arrhythmias — which cause "electrical storms" — that originated in the septum, the thick muscle that separates the heart's two ventricles. This area is virtually impossible to reach with conventional treatment.
INDIANAPOLIS -- Innovative medical records software developed by geriatricians and informaticians from the Regenstrief Institute and the Indiana University Center for Aging Research will provide more personalized health care for older adult patients, a population at significant risk for mental health decline and disorders.
MADISON — For the first time, scientists have transplanted neural cells derived from a monkey's skin into its brain and watched the cells develop into several types of mature brain cells, according to the authors of a new study in Cell Reports. After six months, the cells looked entirely normal, and were only detectable because they initially were tagged with a fluorescent protein.
CHICAGO --- A surprisingly high number of women have postpartum depressive symptoms, according to a new, large-scale study by a Northwestern Medicine® researcher.
This is the largest scale depression screening of postpartum women and the first time a full psychiatric assessment has been done in a study of postpartum women who screened positive for depression.
URBANA – A mutual curiosity about patterns of growth and development in pig brains has brought two University of Illinois research groups together. Animal scientists Rod Johnson and Ryan Dilger have developed a model of the pig brain that they plan to use to answer important questions about human brain development.
"It is important to characterize the normal brain growth trajectory from the neonatal period to sexual maturity," said Johnson.
"Until we know how the brain grows, we don't know what is going to change," added Dilger.
