<br/>Researchers in the United States say playing an instrument and listening to music can significantly enhance the brain's ability to process speech. The team was led by professor Dr Nina Kraus, a neuroscientist from Chicago's Northwestern University in Chicago. In her research, she recorded the brain's response to music using electrodes on the scalp. Professor Kraus said brain's sensitivity to music can be harnessed to sharpen up the response of the brain. Researchers presented these findings at the annual meeting of the American Association for the Advancement of Science in San Diego.<br/><br/>
