Hugg Herr showed the state of the art in bionics at TED, including a touching moment with a dancer first performance on stage after she got her mobility back.
I think there is great potential in the technology shown here, to speed up motor learning: if you ever did some kind of sport that requires good coordination, you know that practice makes you perfect. That’s because you have to build the neural pathways in the cerbellum and basal ganglia to learn the new movements, you can’t just learn them by observation because that stimulates another part of the brain, the temporal lobes.
It could have vast applications from faster physical rehabilitation to recreative uses in sports and dancing.
We live in interesting times!
