I have a STEM student who is doing research on robotic prostheses, a fascinating new area of research. He first looked at nerve reinervation, because this is a focus at Chicago’s Rehabilitation Institute. Later we investigated “mind over matter” methods, whereby brainwaves could be used to teach robots, attached to the subject or not, to do various tasks.
To my surprise, yet another development is taking place in Europe, spinal cord damage repair, which combines an injection of cellular matter and operational conditioning therapy. This I learned from the European equivalent of V Sauce, a Youtube channel called Veritasium.
