Scientists know that music can give intense pleasure by delivering chemical rewards in the brain that are equal to the joy of good food or even sex, but now they think they may have identified the part of the brain where this pleasure starts.
Researchers scanned the brains of subjects while they listened to new songs and asked how much they would spend on buying the tracks. They found that the most popular songs - those which people were prepared to pay more for - were also the ones that elicited the strongest response in the nucleus accumbens, a structure in the centre of the brain that is involved in reward processing.
"This area is important because it's involved in forming expectations and these are expectations that could be rewarding," said Valorie Salimpoor of McGill University in Montreal, Canada. "What makes music so emotionally powerful is the creation of expectation. Activity in the nucleus accumbens normally would indicate that expectations are being met or surpassed."
