Scientists have previously managed to decode words from brain brain wave recordings taken from speech and languages areas of the human brain. Now they have managed to decode music. Patients who have electrodes attached to the surface of their brains were played a song. “Another Brick in the Wall” by Pink Floyd, while their brain waves were monitored. The data from the brain waves were analyzed with the help of artificial intelligence and translated to sound. What came back was muffled, but rhythmic, and the words “All in all, it’s just another brick in the wall” were audible. You can hear that translated sound at the Guardian article. The researchers are convinced that the data would render better sound if more electrodes were used, placed closer together.

What does this mean? The research is intended to find ways to allow those with disabling neurological conditions to communicate using brain waves, which would be a boon to victims of stroke or ALS. Or if you want to look at the dark side, it means that artificial intelligence can read our minds. However, artificial intelligence has yet to learn how to implant electrodes in human brains. -via Damn Interesting
