Scientists’ work on the human brain continues at full speed. In this context; Some devices have already been developed that will enable people who have lost some of their abilities due to brain damage or diseases to regain their lost abilities. Some devices that allow movement and speech with the power of thought are among the most important examples of studies on this subject.
Now, however, there has been a breakthrough in brain activity. A group of scientists discovered that any music can be reproduced by analyzing the listener’s brain waves. Although the result is not perfect for now, experts think that a much better point can be reached with the studies done. In the new future, it will be possible to detect what you are listening to just by examining your brain waves, and even what you are listening to can be recreated in the virtual environment.
Past studies have been concluded thanks to artificial intelligence
A scientist named Ludovic Bellier and his team, who used to work at the University of California and now work at a private company, conducted a research to understand how the human brain perceives music. During this research, coinciding with a study done in 2012, the team first started working on ready-made data.
In a 2012 study, 29 patients with severe epilepsy listened to the first part of Pink Floyd’s song “Another Brick in the Wall”, the activities in the brain were recorded one by one, and then these words were reproduced with special devices. This study was recorded as a first in those years. Ludovic Bellier and his team made a brand new discovery using that data.
*The template prepared for the research. On the left, you see the sound waves emitted by the Pink Floyd song. In the middle is the activity of these waves in the brain. The image on the right represents sound waves created through artificial intelligence. Note the similarity in the waves on the left and right.
The research team used a special AI model that analyzed data from 2012, able to decipher activity in the auditory cortex of the brain and turn that back into music. This artificial intelligence enabled scientists to recreate music recorded with brain waves. The resulting sound is not very clear. It also sounded robotic. However, it should not be forgotten that the artificial intelligence model in question can be trained in the process. In other words, much better results will be obtained in the future.
Here’s a remake of Pink Floyd’s song:
So why is this work “groundbreaking”?
The research may not have excited you enough on its own. However, the research team is more than happy with their results. Because it is believed that with this study, brain-computer interface technologies can be developed. Stating that they are at a very early stage, Bellier said: This method revealed that even the activities in the deepest parts of the brain can be analyzed with brain-computer interfaces.
