The technology that decodes brain signals is advancing rapidly. It can interpret neural activity and reveal what’s going on. Someone’s mind, What they really want to say, or – in the case of a new study – which song they’re listening to.
US Researchers We have been able reconstructA “recognizable” version of a Pink FloydSong based on pulses of brain activity. Temporal lobeListen to the song Another Brick in the Wall Part 1 and get the volunteers involved.
While the song did undergo some initial processing, it was not a final version. Spectrogram formIn terms of fidelity, reverse processing is superior to the forward process because it is compatible with the brain’s audio processing methods.
“We reconstructed Pink Floyd classic song Another Brick in the Wall“Direct human cortical recordings provide insights into the neural basis of music perception as well as future brain decoding applications.” You can find out more about this by clicking here.Neuroscientist Ludovic Belier, University of California Berkeley.
Bellier’s team wanted to see how brain patterns could map to musical elements, such as harmony and pitch. They found that a part called the auditory cortex of the brain was responsible for this mapping. Superior temporal gyrusThe rhythm is closely related to (STG). It appears that this particular area is important when it comes to understanding and perceiving musical rhythm.
The team recruited 29 individuals who already had brain electrodes implanted for management. Their epilepsy. The participants listened to Pink Floyd while 2,668 electrodes were monitored.
Then, all of these data were analyzed using Machine learningThrough what is known as a Decoding model based on regression. The computer algorithms were designed to find correlations between music and brain activity.
The researchers were able to reverse the process and identify Another Brick on the Wall by using the learning process. What the brain was doingThen, it is. It is. Reconstructed trackIt’s a bit muddy and distorted but you can still tell what song it is.
This helps to Continued effortsTo better understand brain patterns, and improve your performance. Brain-machine interfaces.
Imagine restoring the perception of music to those with brain injury, or restoring speech to those who lost it. Think the words you want to say.And the pitch, tone and lyrical movement of these words too.
“For example the findings of musical perception may contribute to development a general decoder that incorporates the prosodic aspects of speech, based on fewer, well-located electrodes,” WriterResearchers in their published papers.
The research has appeared in PLOS Biology.
