Study reveals neural basis of rapid brain adaptation

You detect an object flying at your head. What do you do? You probably first move out of the way -- and then you try to determine what the object is. Your brain is able to quickly switch from detecting an object moving in your direction to determining what the object is through a phenomenon called adaptation.

ROCHESTER, Minn. -- A new Mayo Clinic study (http://newsblog.mayoclinic.org/2008/12/03/brain-tumors-best-treatments-for-long-term-survival/) found that children with low-grade brain tumors (gliomas) (http://www.mayoclinic.org/brain-tumors/) who undergo aggressive surgery to completely remove the tumor have an increased chance of overall survival.

RIVERSIDE, Calif. – Elderly adults can improve their vision with perceptual training, according to a study from the University of California, Riverside and Boston University that has implications for the health and mobility of senior citizens.

The study, "Perceptual learning, aging, and improved visual performance in early stages of visual processing," appears in the current online issue of the Journal of Vision. It was funded by a $3.5 million grant from the National Institute on Aging.

A new study has found that low amounts of albumin in the urine, at levels not traditionally considered clinically significant, strongly predict faster cognitive decline in older women. The study involved more than 1,200 women aged >70 years in the Nurses' Health Study who were phoned every two years for three cycles and tested for general cognition, verbal/word memory, verbal fluency (speed in making word associations), and working/short-term memory.

FORT COLLINS - In the last 50 years, modern medicine has made astounding advances in surgery, yet many of today's veterinary and human medicine students still hone basic surgical and suturing skills on carpet pads and pig's feet before transitioning to a live patient. An invention by Colorado State University veterinarians provides students with artificial body parts that look, feel, behave, and even bleed just like real skin, muscles and vessels.

COLUMBIA, Mo. – As the number of children diagnosed with autism spectrum disorders continues to increase, the one thing that won't change is the need for those children to develop social skills. Now, researchers at the University of Missouri are developing an effective social competence curriculum, with a virtual classroom component, that could help educators meet the demand of this growing population.

A recent study (1) suggesting that amyotrophic lateral sclerosis (ALS) may be attributed to "repetitive head trauma experienced in collision sports" lacks scientific epidemiological evidence to support this claim. In a review of the 12-patient study, several experts specializing in motor neuron diseases challenge the findings as entirely pathological and without clinical merit. Their editorial, which aims to dispel doubts of Lou Gehrig's ALS diagnosis, is now available online in the peer-reviewed journal Muscle & Nerve.

College students participating in a new study on online courses said they felt less connected and had a smaller sense of classroom community than those who took the same classes in person – but that didnt keep online students from performing just as well as their in-person counterparts.

Physical activity promotes changes in the brain that may protect high-risk individuals against cognitive decline, including development of Alzheimer's disease, according to a new study done at the University of Wisconsin-Milwaukee (UWM).

J. Carson Smith, an assistant professor of health sciences, included in the study both people who carry a high-risk gene for Alzheimer's disease, and other healthy older adults without the gene.

A treatment model designed to accommodate the beliefs and concerns of Chinese immigrants appears to significantly improve the recognition and treatment of major depression in this typically underserved group. In a report in the December American Journal of Public Health, a Massachusetts General Hospital (MGH) research team describes how their model for screening and assessing patients for depression in a primary care setting increased the percentage of depressed patients entering treatment nearly sevenfold.

(Boston) - Five U.S. federal agencies recently cosponsored a set of expert work groups to formulate common data elements for research related to psychological adjustment and traumatic brain injury (TBI). Danny G. Kaloupek, PhD, associate professor of psychiatry and behavioral neuroscience at Boston University School of Medicine, chaired the work group on posttraumatic stress disorder (PTSD). Dr.

Successfully treating and reversing the effects of multiple sclerosis, or MS, may one day be possible using a drug originally developed to treat chronic pain, according to Distinguished Professor Linda Watkins of the University of Colorado at Boulder.

Watkins and her colleagues in CU-Boulder's department of psychology and neuroscience discovered that a single injection of a compound called ATL313 -- an anti-inflammatory drug being developed to treat chronic pain -- stopped the progression of MS-caused paralysis in rats for weeks at a time.

Scientists at Johns Hopkins have identified a compound that could be used to starve cancers of their sugar-based building blocks. The compound, called a glutaminase inhibitor, has been tested on laboratory-cultured, sugar-hungry brain cancer cells and, the scientists say, may have the potential to be used for many types of primary brain tumors.
