“We don’t need no thought control”: Pink Floyd music read from brain waves

For more than ten years, the University of California at Berkeley (UC Berkeley) has been working on measurements to analyze brain waves. The team of scientists led by Ludovic Bellier and Robert Knight has now achieved a milestone in their research: They played the song “Another Brick in the Wall, Part 1” from Pink Floyd’s concept album “The Wall” from 1979 to 29 participants and were able to subsequently restore parts of the song on the computer from the electrode measurements.

“All in all it’s just another brick in the wall”

While the words were slurred in the computer analysis, the UC Berkley researchers said, the rhythm of the iconic rock song could be read using a brain-computer interface. The researchers were also able to recognize the line “All in all it’s just another brick in the wall” on the computer.

The team from the University of California at Berkeley hopes to be able to use this technique to restore the musicality of speech to stroke patients or people with paralysis. This is not yet possible with today’s techniques and the reconstruction of the language sounds robotic. “In the future, thanks to advances in brain-machine interfaces, it will be possible to give back musicality to people who need it through brain implants,” said Robert Knight of UC Berkley.

For this study, however, intracranial electroencephalography (iEEG) was necessary, in which electrodes are surgically guided through the skull to the surface of the brain. This was the only way for the scientists to get close enough to the hearing center of the subjects who were actually being prepared for an epilepsy operation.
