Scientists have found a way to rejuvenate the brain as March 8, 2013
Perhaps it is no secret that the brain child more prone to learning new things, than the adult brain. If you do not believe me, just ask any adult who is trying to learn, for example, a new language. The flexibility of the young brain also makes it easier to rehabilitate from injuries. Researchers at Yale University have found an efficient way, which allows you to “transform” the old brain young again.
Once we reach adulthood, our brains are fully formed and becomes less pliable for learning new information. All this is due to a single gene, which slows the rapid changes in the synaptic connections between neurons. Scientists at Yale for several months, followed by synapses mice and were able to identify a gene Nogo Receptor 1 – the same key genetic element responsible for the maturation of the brain.
Scientists were able to isolate the gene in mice and this has led to surprising results. Researchers have been able to achieve that same level of plasticity, which is available for the young brain. Old mouse brain without the gene Nogo Receptor could recover from a traumatic brain injury as fast as the brains of young mice. Moreover, keep the mouse with the “updated” by the brain, too, as was young, she improved motor function and was able to perform more complex experimental problems.
“The study showed that by manipulating the gene Nogo Receptor in the human brain can accelerate convalescence, such as concussion,”
– Said graduate student Feras Akbik (Feras Akbik) from Yale University.
Further study also showed that the process of memory loss is also slowed – mouse without Nogo Receptor rid of stressful memories are much faster than the one that had this receptor. Scientists say that this discovery will also be able to help people more quickly out of the post-traumatic situations.
