The music that makes the foot tap,the fingers snap,and the pulse quicken stirs the brain at its most fundamental levels,suggesting that scientists one day may be able to return damaged minds by exploiting rhythm,harmony,and melody,according to new research. "Undeniably,there is a biology of music",said Harvard university medical school neurobiologist mark jude tramo. "music is biologically part of human life,just as music is aesthetically part of human life". RESEARCHERS FOUND THAT THE BRAIN: Responds directly to harmony. Neuroscientists discovered that different parts of the brain involved in emotion are activated depending on whether the music is pleasant or unpleasant. Interprets written music in an area on the brains right side,that region corresponds to an area on the opposite side of the brain known to handle written words and letters. So,researchers uncovered an anatomical link between music and language. Grows in response to musical training. In a study of classically trained musicians,researchers discovered that male musicians have significantly larger brains than men who have not had extensive musical training. Overall,music seems to involve the brain at almost every level,and researchers are already looking for ways to harness the power of music to change the brain. Preliminary research also suggests that music may play some role in enhancing intelligence. Indeed,so seductive is the possibility that music can boots a child s IQ that some politicians are lobbying for schools children to be exposed regularly to Mozart sonatas,although such research has yet to be confirmed. The scientists said the new research could help the clinical practice of neurology,including cognitive rehabilitation. As a therapeutic tool,for example,some doctor already use music to help rehabilitate stroke patients. Surprisingly,some stroke patients who have lost their ability to speak retain their ability to sing,and that opens an avenue for therapists to retrain the brains speech centers.
