I did a PhD in brain-computer interfaces, including EEG and implanted electrodes. BCI research to a big extent focuses on helping paralyzed individuals regain communication. Unfortunately, EEG doesn’t provide sufficient signal-to-noise ratio to support good communication speeds outside of the lab with Faraday cages and days/weeks of de-noising including removing eye-movement artifacts in the recordings. This is a phy…
Recently, a Swiss-French team made the communication between the brain and the legs possible, and the device looked relatively mature. I think patient had nerves damaged in the vertebral column. What do you think about it ? Looked like a promising development. https://actu.epfl.ch/news/thought-controlled-walking-again-a...
Not OP, but Ttat article's use of the word "implant" implies a much more invasive device, which means a way better signal. Additionally, the output, while still complex, is far from the level of decoding of thought presented here. Thus, while still impressive, it is less of a leap from existing technology, and much more within the realm of what we know is very much possible.
