Dr. Robert Knight, professor of psychology and neuroscience, and Ludovic Bellier,  postdoctoral researcher in human cognitive neuroscience, analyzed the electrical activity of 29 epileptic patients undergoing brain surgery at Albany Medical Center in New York. The patients, who had volunteered for research, had electrodes placed onto the surface of their brain. While receiving surgery they hoped would cure intractable seizures, Pink Floyd’s 1979 single “Another Brick in the Wall, Part 1” played in the operating room. Using artificial intelligence, Bellier was able to reconstruct the song from that electrical activity in each patient’s brain, according to an article published in the journal PLoS Biology.
