In what seems like something out of a sci-fi movie, scientists have plucked the famous Pink Floyd song “Another Brick in the Wall” from individuals’ brains.
Previously, researchers have used electrodes, computer models and brain scans to decode and reconstruct individual words and entire thoughts from peoples brain activity (SN: 6/3/23, P. 14).
The new study, published August 15 in PLOS Biology, adds music into the mix, showing that songs can also be decoded from brain activity and revealing how different brain areas pick up an array of acoustic elements. The finding may eventually help improve communication devices used by people with paralysis or other conditions that limit the ability to speak.
Neuroscientist Ludovic Bellier of the University of California, Berkeley and colleagues decoded the song from data captured by electrodes on the brains of 29 people with epilepsy. While in the hospital being monitored for the disorder, the individuals listened to the 1979 rock song.
People’s nerve cells, particularly those in auditory areas, responded to hearing the song. The electrodes detected not only neural signals associated with words, but also rhythm, harmony and other musical aspects. With that information, the researchers developed a computer model to reconstruct sounds from the brain activity data, and found that the model could produce sounds that resemble the song.
“It’s a real tour de force.’ says neuroscientist Robert Zatorre of McGill University in Montreal. “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”.
