A More Efficient Brain: Speaking Another Language or Learning Music

  Bilinguals and musicians use fewer brain resources when completing a working memory task.
  Using brain functional imagery, musicians remembered the type of sound presented to them faster than non-musicians, while bilinguals and musicians performed better on locating the source of a sound.
  Bilinguals performed about the same as individuals who spoke only one language and were not musicians on remembering the sound, but they showed less brain activity when completing the task.
