Music On The Brain

Why does music sometimes get stuck in your head? “A team from Dartmouth College, Hanover, New Hampshire, played music to volunteers while using a technique called functional magnetic resonance imagery to scan their brains. As the music was played, parts of the tune were cut. Researchers found volunteers mentally filled in the blanks if a familiar song was missing snippets, although the same effect was not seen with unfamiliar tunes. The brain activity was picked up by the scan and found to be centred in the auditory cortex.”
