Researchers at Northwestern University recorded the auditory brainstem responses of college students — that is to say, their electrical brain waves — in response to complex sounds. The group of students who reported musical training in childhood had more robust responses — their brains were better able to pick out essential elements, like pitch, in the complex sounds when they were tested. And this was true even if the lessons had ended years ago.
Indeed, scientists are puzzling out the connections between musical training in childhood and language-based learning — for instance, reading. Learning to play an instrument may confer some unexpected benefits, recent studies suggest. - NYTimes.com
