Lifelong bilinguals may have more efficient brains – The Chart - CNN.com Blogs


Lifelong bilinguals may have more efficient brains – The Chart - CNN.com Blogs: Neuroscientists have been discovering mounting evidence that being fluent in more than one language protects against age-related cognitive declines. But there's still the major question: Why?

Researchers used functional magnetic resonance imaging (fMRI) to get a closer look at the brains of both bilinguals and monolinguals, comparing how their activity differs during specific tasks. This new study, published Tuesday in the Journal of Neuroscience, expands upon previous ideas that bilinguals tend to show superior task-switching abilities compared to monolinguals. The study was led by Brian Gold of the University of Kentucky in Lexington.
