We have all experienced it; hearing a new song that you really like, and rushing to your preferred digital music distributor to buy it. Researchers at Science Magazine have recently determined why we have this feeling. Hearing a new song activates a part of the brain called the Nucleus Accumbens. This part of the brain is used to make predictions, which it tries to do with a new song as well. When it correctly predicts where the song will go, it stimulate the feeling of pleasure, given that it is located within the reward center of the brain. However, the nucleus accumbens doesn’t work alone. It has been found that it works in conjunction with three other parts of the brain: one looks for patterns, another compares the music to sounds previously heard and the last checks for emotional ties. According to Robert Zatorre of the Montreal Neurological Institute at McGill University, these four regions of the brain “work overtime” when listening to a new song. This development has been taken further, and now researchers believe that they can correctly predict what a person is willing to spend on a new song judging by the amount of activity that their nucleus accumbens displays. Aniruddh Patel of Tufts University commented that a music store such as Google Music and iTunes was “a very clever idea” that plays to “an old theory in music cognition”. Some researchers believe that these discoveries will lead to breakthroughs in speech and sound recognition in the future.
