London: Scientists have unveiled a new feel good "patch" which they say could help fight depression while you sleep. Developed by researchers at the University of California in Los Angeles, the device when stuck on to the forehead uses tiny electrical impulses to stimulate the trigeminal nerve in the head. This nerve, which sits just beneath the forehead and often described as the "USB port into the brain", leads to areas in the brain which are thought to control mood, the Daily Mail reported. The device, which contains electrodes, is linked by two wires to a generator the size of a mobile phone, which can be worn around the waist. In a trial on a small group of patients suffering from major depressive disorder, the researchers found the patients reported a 50 per cent reduction in symptoms after using the patch for eight hours a night for eight weeks. The patients, who had all suffered from major depressive symptoms for more than four months and not responded to at least one antidepressant, reported feeling better after just two weeks, the researchers said.
