DURHAM, N.C. -- Elderly adults who perform as well as younger adults on certain cognitive tests appear to enlist the otherwise underused left half of the prefrontal cortex of their brain in order to maintain performance, Duke University neuroscientists have found. In contrast, elderly people who are not "high performers" on the tests resemble younger adults in showing a preferred usage of the right side of the prefrontal cortex.
