Moving Music Spurs Dopamine Spike in Brain

Today Trevor Gibbons, 54, can walk, talk, and even sing, despite having lost the use of his vocal cords and much of the right side of his body after having two strokes and falling from a 4-story window in 2001. The miracle remedy he credits with his ability to overcome the pain, disability, and depression that accompanied his accident? Music.

"One particular day, an intern named Lucy at Beth Abraham hospital [in New York city]…where I was being treated… came with a portable piano and tried to get me to listen to music even though I couldn't sing along at that point," the Bronx man says.

"I had to take so many narcotics for the pain, but when I heard the music, got into the music, the pain would just fade away," he says. When Lucy played "This Little Light of Mine," which Gibbons' grandmother would sing to him as a little boy in Barbados, it marked a turning point in his recovery and jumpstart a life-long dedication to music therapy.

Music has long been known as a balm for an ailing mind and body, but until now, nobody understood why. Researchers have documented for the first time exactly how good music changes the chemistry in the brain by boosting the pleasure chemical, dopamine.

Researchers from McGill University in Canada monitored the brains of eight 19-24 year olds as they listened to self-selected music using PET scans and MRIs. Music ranged from classical to jazz to punk and even techno – the only requirement was that the music be so good for the participant that it moved him or her to chills.

When compared to "neutral" music, listening to chill-inducing music gave participants a six to nine percent increase in dopamine. Results fromt the study will be published Sunday in Nature Neuroscience

"Before, researchers had shown that the pleasure centers in the brain light up when listening to good music, but they couldn't tell for sure if it was dopamine," says lead author and neuroscience Ph.D. candidate at McGill University, Valorie Salimpoor. This is the first time that the actual surge in dopamine levels has been shown, she says.

Moving Music and Chills of Pleasure

Dopamine is the "brain's motivation system" Salimpoor says. It's in the interest of our own survival that we enjoy things like sex and eating, and "the [dopamine] system is an ancient reward system that evolved" to reinforce these necessary behaviors, she adds.

Why music has evolved to stimulate a similar pleasure reward is not as straightforward. "It's an intellectual reward as we focus on and follow the notes," Salimpoor says. "It seems relatively unique to humans that we have this higher order ability to experience pleasure."

Researchers asked participants to choose their own "chill-inducing music", as long as it was instrumental only. Because our brains are trained to respond in certain ways to the human voice, they allowed only instrumental pieces to avoid muddling signals about reaction to the music.

Researchers noted that while the pleasure center was activated throughout the music, getting chills from particular passages caused a spike in dopamine during and in the few seconds preceding it.

"The music is stimulating an emotional response and this response is both causing the chills and the surge in dopamine," Salimpoor says. (Chills don't stimulate the dopamine, they just happen to be a useful marker of heightened moments of enjoyment.)
