Report  Web desk : LONDON Scientists have uncovered a method for improving short-term working memory by stimulating the brain with electricity. Researchers found that applying a low-voltage current can synchronise brain waves, enabling people to perform better at tasks involving working memory. The hope is that the approach could one day be used to bypass damaged areas of the brain and send signals in people with traumatic brain injury, stroke or epilepsy. The team found that buzzing the brain with electricity could give a performance boost to the same memory processes used when people try to remember names at a party, telephone numbers, or even a short shopping list. The brain is in constant state of chatter, with this activity seen as brainwaves fluctuating at different frequencies and in different regions, keeping a steady beat. In a new study, a team from Imperial College London found that applying a weak electrical current through the scalp of participants helped to align different parts of the brain. 02
