Launching electric current in the brain for just 25 minutes reversed the decline in working memory badociated with aging, scientists said Monday. Although researchers have tested the effects on people for only 50 minutes, this discovery offers hope for a reinforcement of a mental function so essential to reasoning, problem-solving and planning, that it has been called the foundation of intelligence.
By stimulating the brain in specific regions with an AC current, "we can bring back the higher working memory function you had when you were much younger," Robert Reinhart, researcher in psychology.

In order for the alternating current, delivered by electrodes embedded in a skull cap, to be used to treat deficits in the working memory, it will however have to overcome a long list of obstacles, starting with the proof of its safety. But whether the results published in Nature Neuroscience or not lead to practical applications, they provide some of the strongest evidence to date of why older people are not as good at remembering a number of phone that we just heard or address in a fair place. text seen: the brain circuits become functionally disconnected and fall out of sync.
