He believes that using a higher density of electrodes might improve the quality of their reconstructions: “The average separation of the electrodes was about 5mm, but we had a couple of patients with 3mm [separations] and they were the best performers in terms of reconstruction,” Knight said.
“Now that we know how to do this, I think if we had electrodes that were like a millimetre and a half apart, the sound quality would be much better.”
As brain recording techniques improve, it may also become possible to make such recordings without the need for surgery – perhaps using sensitive electrodes attached to the scalp.

Scientists in Texas developed a GPT-like AI system that reads minds
The scientists recently published a paper in Nature Neuroscience exploring using AI to non-invasively translate human thoughts into words in real time.
According to the researchers, current methods for decoding thoughts into words are either invasive — meaning they require surgical implantation — or limited in that they “can only identify stimuli from among a small set of words or phrases.”
The team at Austin circumvented these limitations by training a neural network to decode functional magnetic resonance imaging (fMRI) signals from multiple areas of the human brain simultaneously.

‘Mind-Reading’ Technology Translates Brainwaves into Photos
In an article published in Nature, researchers at Radboud University in the Netherlands revealed the results from an experiment where they showed photos of faces to two volunteers inside a powerful brain-reading functional magnetic resonance imaging (fMRI) scanner. … As the results of the experiment show, the fMRI/AI system was able to almost identically reconstruct the original images that the volunteers were shown. https://petapixel.com/2022/08/23/mind-reading-technology-translate-brainwaves-into-photos/

Meta AI can tell which words you hear by reading your brainwaves
An AI developed by Facebook’s owner Meta can scan a person’s brainwaves to “hear” what someone else is saying to them. https://www.newscientist.com/article/2335961-meta-ai-can-tell-which-words-you-hear-by-reading-your-brainwaves/
