It is one of society's most common vexations: forgetting a name. Now, scientists at Temple and the University of Pennsylvania have hit on an intriguing remedy —a weak dose of electricity to the head. The technique is called transcranial direct current stimulation. The way this mild stimulation seems to work is by making neurons more likely to fire, said Temple psychologist Ingrid Olson, senior author of the study. "It kind of makes them more ready to act," she said of the neurons. No adverse effects have been found.
