A Generation Gap in Brain Activity
Abstract: Science 296, 2131-2133 (2002).
As the field of cognitive neuroscience matures, researchers are using imaging studies to get a better fix on what happens to the brain as it ages. Some neuroscientists have observed that certain brain areas physically shrink over time, whereas others have found that older people are more broad-minded: They use both frontal lobes when performing working memory tasks that are specialized according to hemisphere in younger brains. Exactly how these changes relate to cognitive failings in old age remains unclear, however.
