The technique could be used to improve devices that allow communication from people unable to speak.
To decode the song, neuroscientist Ludovic Bellier of the University of California, Berkeley and colleagues analyzed the brain activity recorded by electrodes implanted in the brains of 29 individuals with epilepsy. While in the hospital undergoing monitoring for the disorder, the individuals listened to the 1979 rock song.
“It’s a real tour de force,” says Robert Zatorre, a neuroscientist at McGill University in Montreal who was not involved in the study. “Because you’re recording the activity of neurons directly from the brain, you get very direct information about exactly what the patterns of activity are.”The study highlights which parts of the brain respond to different elements of music.
“Music is a core part of human experience,” says Bellier, who has been playing instruments since he was 6 years old. “Understanding how the brain processes music can really tell us about human nature. You can go to a country and not understand the language, but be able to enjoy the music.”
