Electric Stimulation Improves the Working Memory of Older People

Electric stimulation improves memory
During memory tasks, brain activity associated with working memory lights up in the brain of a 20-year-old (left), but remains dormant in the brain of a person in their 70s (middle).

The performance of our working memory deteriorates as we age. As we get older, it becomes increasingly difficult to form new memories and hold on to them. Now researchers at Boston University have shown that it is possible to improve memory in older folks. They used external electric stimulation to give 70-year-olds the memory abilities […]
