Researchers at the University of Puerto Rico, School of Medicine have found a way to pharmacologically induce a memory of safety in the brain of rats. As reported in the June, 4 2010 issue of Science, administering brain-derived neurotrophic factor (BDNF) into the prefrontal cortex prevented rats from expressing fear to a tone that had been previously paired with a shock. Rats given BDNF acted as if they had received repeated presentations of the tone without the shock, a procedure called...

Finding suggests possibilities for future treatment of anxiety disorders Researchers have found a way to pharmacologically induce a memory of safety in the brain of rats, mimicking the effect of training. The finding suggests possibilities for new treatments for individuals suffering from anxiety disorders. Rats normally freeze when they hear a tone they have been conditioned to associate with an electric shock. The reaction can be extinguished by repeatedly exposing the rats to the tone with...

OAKLAND, Calif., May 26 /PRNewswire/ -- Most young people experience learning losses when they do not engage in educational activities during the summer break. According to the National Summer Learning Association (www.summerlearning.org), research spanning 100 years shows that students typically score lower on standardized tests at the end of summer vacation than they do on the same tests at the beginning of the summer. For students who are already struggling or reading below grade...

A cat can recognize a face faster and more efficiently than a supercomputer. That's one reason a feline brain is the model for a biologically-inspired computer project involving the University of Michigan. U-M computer engineer Wei Lu has taken a step toward developing this revolutionary type of machine that could be capable of learning and recognizing, as well as making more complex decisions and performing more tasks simultaneously than conventional computers can. Lu previously built a...

UCSF scientists report that they were able to prompt a new period of "plasticity," or capacity for change, in the neural circuitry of the visual cortex of juvenile mice. The approach, they say, might someday be used to create new periods of plasticity in the human brain that would allow for the repair of neural circuits following injury or disease. The strategy "“ which involved transplanting a specific type of immature neuron from embryonic mice into the visual cortex of young mice...

TAU researcher uses magic tricks to treat children with locomotor disabilities It's often hard to motivate youngsters with physical disabilities. But a new approach from a Tel Aviv University researcher bridges the worlds of behavior and science to help kids with paralysis and motor dysfunction improve their physical skills and inner confidence "” using a trick up her sleeve called "magic." Dr. Dido Green of Tel Aviv University's School of Health Professionals developed an innovative...

Scientists have gained new insight into why a relatively short-term hearing deprivation during childhood may lead to persistent hearing deficits, long after hearing is restored to normal. The research, published by Cell Press in the March 11 issue of the journal Neuron, reveals that, much like the visual cortex, development of the auditory cortex is quite vulnerable if it does not receive appropriate stimulation at just the right time. It is well established that degraded sensory experience...

Doctors treat millions of children with Ritalin every year to improve their ability to focus on tasks, but scientists now report that Ritalin also directly enhances the speed of learning. In animal research, the scientists showed for the first time that Ritalin boosts both of these cognitive abilities by increasing the activity of the neurotransmitter dopamine deep inside the brain. Neurotransmitters are the chemical messengers neurons use to communicate with each other. They release the...

Virtual reality game technology using Wiiâ“ž¢ may help recovering stroke patients improve their motor function, according to research presented as a late breaking poster at the American Stroke Association's International Stroke Conference 2010. The study found the virtual reality gaming system was safe and feasible strategy to improve motor function after stroke. "This is the first randomized clinical study showing that virtual reality using...

TAU finds new synthetic supplement improves memory and staves off age-related memory loss Those who live in industrialized countries have easy access to healthy food and nutritional supplements, but magnesium deficiencies are still common. That's a problem because new research from Tel Aviv University suggests that magnesium, a key nutrient for the functioning of memory, may be even more critical than previously thought for the neurons of children and healthy brain cells in adults. Begun at...
