As the chords of Pink Floyd's 'Another Brick in the Wall, Part 1,' filled the surgery suite, neuroscientists at Albany Medical Center diligently recorded the activity of electrodes placed on the brains of patients undergoing epilepsy surgery.
Neuroscientists recorded electrical activity from areas of the brain as patients listened to a 3-minute snippet of the Pink Floyd song, “Another Brick in the Wall, Part 1.” Using artificial intelligence software, they were able to reconstruct the song from the brain recordings. This is the first time a song has been reconstructed from intracranial electroencephalography recordings.
Because these intracranial electroencephalography recordings can be made only from the surface of the brain—as close as you can get to the auditory centers—no one will be eavesdropping on the songs in your head anytime soon.

"Noninvasive techniques are just not accurate enough today. Let's hope, for patients, that in the future we could, from just electrodes placed outside on the skull, read activity from deeper regions of the brain with a good signal quality. But we are far from there," Bellier said.Reading your mind? Not yet
