Google and Osaka University in Japan have conducted groundbreaking research that explores a fascinating technique for converting brain activity into music. During the study, five volunteers were placed inside an fMRI (functional magnetic resonance imaging) scanner and exposed to over 500 tracks across 10 different musical genres. The resulting brain activity was captured and incorporated into Google’s AI music generator, Music LM. This allowed the software to be conditioned on the unique brain patterns and responses of each individual.
The generated music closely resembled the stimuli received by the subjects, albeit with subtle semantic variances. According to the abstract of the research report, “The generated music resembles the musical stimuli that human subjects experienced, with respect to semantic properties like genre, instrumentation, and mood.” This highlights the successful correlation between brain activity and AI-generated music.
Additionally, the study revealed a fascinating overlap between the brain regions responsible for processing textual information and the brain regions associated with music. There were similarities between certain components of Music LM and the brain activity observed in the auditory cortex.
The researchers concluded that there is a significant correlation between the internal representations of Music LM and brain activity in certain regions when exposed to the same music. By utilizing data from these regions as input for Music LM, they were able to predict and reconstruct the types of music to which the human subjects were exposed.
While this research brings us closer to the possibility of translating thoughts into music using highly intelligent software, the scientists acknowledged the challenges of building a universal model. Due to the significant variations in brain activity among individuals, creating a model capable of accurately interpreting and generating music solely from human imagination would be difficult.

Overall, Google and Osaka University’s collaboration has demonstrated the remarkable capability of converting brain activity into music and highlights the intersecting areas between neuroscience and AI. By nurturing this research, we may witness future breakthroughs in bridging the gap between the human mind and the creation of music.
