AI recreates clip of Pink Floyd song from recordings of brain activity

An artificial intelligence has created a passable cover of a Pink Floyd song by analysing brain activity recorded while people listened to the original. The findings further our understanding of how we perceive sound and could eventually improve devices for people with speech difficulties. Robert Knight at the University of California, Berkeley, and his colleagues studied recordings from electrodes that had been surgically implanted onto the surface of 29 people's brains to treat epilepsy. The participants' brain activity was recorded while they listened to Another Brick in the Wall, Part 1 by Pink Floyd. By comparing the brain signals with the song, the researchers identified recordings from a subset of electrodes that were strongly linked to the pitch, melody, harmony and rhythm of the song.
