Unlocking the Secrets of the Mind: Music Recreated from Brain Waves

Researchers at the University of California Berkeley have made an astonishing breakthrough in the field of neuroscience and artificial intelligence. Dr. Robert Knight, a distinguished professor of psychology and neuroscience, and Ludovic Bellier, a seasoned postdoctoral researcher, teamed up to delve deep into the inner workings of the human brain with a focus on its response to music.

The Experiment: Pink Floyd Meets Neuroscience

  • The subject of Study: Utilizing the 1979 classic “Another Brick in the Wall, Part 1” by Pink Floyd, the researchers embarked on a unique experiment.
  • Participants: 29 epileptic patients at Albany Medical Center in New York, undergoing brain surgery.
  • Procedure: Electrodes were placed on the surface of the patient’s brain. While in surgery, the Pink Floyd track played, and the brain’s electrical activity was closely monitored. –
  • AI Application: Using artificial intelligence, Bellier reconstructed the song purely based on the brain activity recorded.

Music: A Universal Language

Dr. Knight stated the reason behind choosing a musical piece for their study: music’s universality. He believes that music, a phenomenon predating language, can bridge cultural divides. It adds emotion, rhythm, and semantics, enhancing our comprehension of language. This study, aiming to improve brain-machine interfaces, can potentially aid patients with speech disorders, non-verbal apraxia, stroke, and ALS.

Future Implications: From Medical Needs to Daily Life

Bellier highlighted that while the primary focus is on medical applications, this revolutionary technology might be utilized in everyday life in the future. As brain recording tech evolves, transmitting thoughts might become possible even without invasive surgery.

  • Keyboard for the Mind: The A.I. offers a form of “mind-keyboard”, allowing one to potentially just think of an action for it to be executed. For instance, merely thinking of ordering an Uber might summon the ride.
  • Privacy Concerns: Addressing potential apprehensions, Bellier mentions that current encryption methods can secure wireless EEG signals, ensuring that privacy is maintained.

Neurological Discoveries: Insights into Brain Activity

The study provided an array of revelations:

  • The right hemisphere, particularly the superior temporal gyrus, was predominantly active during the listening experience.
  • The left brain was mildly stimulated.
  • The brain’s temporal lobe lit up with the rhythm guitar’s 16th notes when played at 99 beats per minute.

Expanding the Horizon: Potential Uses & Ethical Considerations

Understanding the brain’s perception of music can pave the way for sophisticated devices that can assist people with speech difficulties, delivering a more human-like communication method. Dr. Knight emphasized the potential of creating devices that truly sound like human interaction, especially for patients with ALS or aphasia.

  • AI and Music Composition: Bellier speculates that if AI can capture imagined music, not just heard, it might even be employed in music composition.
  • Copyright Concerns: The recreation of songs through brain activity could lead to copyright issues. Jennifer Maisel from the Rothwell Figg law firm in Washington DC expresses intrigue over the concept of authorship in such scenarios.


The groundbreaking study by Dr. Knight and Bellier has set the stage for a myriad of potential applications and innovations in the realm of neuroscience, artificial intelligence, and daily life. The convergence of these fields is not just reshaping our understanding of the human brain but also redefining our relationship with technology.
