Brain-to-Audio: A Revolutionary Breakthrough in Neurotechnology

Imagine a world where your thoughts could translate into music. That may sound like a scene straight out of a science-fiction movie, but recent developments in neurotechnology have brought us closer to making it a reality. In this article, we’ll explore the world of Brain-to-Audio technology and how it functions. We'll go through the experiment the scientist conducted for its activation and its possibility.

Understanding EEG (Electroencephalography)

Before diving into Brain-to-Audio, we need to understand electroencephalography better - a technique that records electrical activity in the brain using electrodes placed on the scalp. The technique allows us to analyze primary features of the brain, and it has been primarily used for diagnosing epileptic seizures and sleep disorders.

Intracranial EEG: The Invasive Technique

Intracranial EEG requires electrodes to be placed on the surface of the brain, making it an invasive technique. However, this technique shines in providing high-quality brain data, making it possible to listen to the brain's electrical activity straight from its surface.

Brain-to-Audio: What is it?

Brain-to-Audio is a neurotechnology that decodes brain data into sound. In simpler words, the technique allows us to listen to music straight from the brain. It's like having a music player connected directly to the brain.

The Experiment Design

To illustrate Brain-to-Audio technology, the scientists decided to conduct an experiment where they played the Pink Floyd classic, "Another Brick in the Wall" to twenty-nine patients. Then, scientists recorded brain activity of the patients and created a spectrogram from information obtained from the brain.

Decoding Neural Activity

Decoding is the process of translating neural activity observed in the brain into coded symbolic information. Then, the process of creating a spectrogram begins. Here, decoding neural information is done using a digital neural network.

Spectrogram: The Key to Brain-to-Audio

The auditory spectrogram of a song transcribes the frequencies and amplitudes of sound over time, making it possible to Visualize sound via its frequency composition. It enables us to look at the song and understand better where We Are and what is happening.

Quality of Reconstruction v/s Number of Electrodes

Adding more electrodes typically increases the resolution of the information we get but also increases the noise as well.

Brain-to-Text Transcription

Brain-to-Audio technology offers not only the possibility of hearing the music but also the potential for reconstructing the musicality of speech. Suppose we combine advancements in brain-to-text technology with this. In that case, we could help people who are unable to communicate with us through speech to not only write to us but also have their speech reconstructed.

Advancements in Brain-Computer Interface Technology

The advancements made in brain-computer interface technology are nothing short of revolutionary. An experiment conducted in a paralyzed subject showed that the subject could imagine writing letters and have them magically appear on a computer screen. The brain-computer interface technology could transcribe 90 characters per minute with over 94% accuracy, which can be improved to over 99% of accuracy with an additional autocorrect technique.

Pros and Cons of Brain-to-Audio Technology

One of the possible applications of the technology can help us learn more about people with neurological disorders such as strokes, language impairments, and degenerative brain disorders like Parkinson’s or Alzheimer’s. However, invasive nature of intracranial EEG makes it less preferable if non-invasive techniques sufficiencies can justify it.

Conclusion

Brain-to-Audio technology is a promising breakthrough in the world of neurotechnology. A Fusion of brain-to-text and brain-to-audio technology can revolutionize the communication process for people who have lost the ability to speak. Though the techniques are invasive, they open doors for further research.
