Why is it that only some drug users become addicts? This is the question that has been addressed by the teams of Pier Vincenzo Piazza and Olivier Manzoni, at the Neurocentre Magendie in Bordeaux (Inserm unit 862). These researchers have just discovered that the transition to addiction could result from a persistent impairment of synaptic plasticity in a key structure of the brain. This is the first demonstration that a correlation exists between synaptic plasticity and the transition to...

The adult brain, long considered to be fixed in its wiring, is in fact remarkably dynamic. Neuroscientists once thought that the brain's wiring was fixed early in life, during a critical period beyond which changes were impossible. Recent discoveries have challenged that view, and now, research by scientists at Rockefeller University suggests that circuits in the adult brain are continually modified by experience. The researchers, led by Charles D. Gilbert, Arthur and Janet Ross Professor and...

An innovative use of virtual reality is emerging as a major technique in brain recovery for stroke patients, Dr. Mindy Levin told the Canadian Stroke Congress today. "Our brains have an extraordinary plasticity which can limit the damage caused by some types of stroke," says Dr. Mindy Levin, professor in the School of Physical and Occupational Therapy at McGill University. "Together with Dr. Heidi Sviestrup from the Faculty of Health Sciences at the University of Ottawa, our rehab program...

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...

abrosia
  • Wasting away as a result of abstinence from food.
The word 'abrosia' comes from a Greek roots meaning 'not' and 'eating'.
