Another Brick in the Wall, Part 1
solely using brain activity. It utilized a technique known as stimulus reconstruction and built on previous innovations allowing researchers to recreate a song akin to the one a person had heard. The 29 participants had pharmacoresistant epilepsy and intracranial grids or strips of electrodes which had been surgically implanted to aid in their treatment. Researchers utilized these electrodes to record activity across multiple auditory regions of the individuals’ brains that process aspects of music like lyrics and harmony — while the participants actively listened to. The entirety of the recordings took place at Albany Medical Center, in upstate New York.
Scientists used AI to analyze then create a copy of the words and sounds participants had heard. Though the final product was quite muffled, but the song is clear to anyone listening so you can check it out for yourselfa. The researchers are also confident that they could increase its quality in future attempts., mostly in the superior temporal gyrus and especially when absorbing unique music. There was also a small level of stimulation in the left side of the brain.
