Idk what brain region it was in, but I once drove a guy who had some sort of brain stimulation for Parkinson’s. Had this match-box sized box of batteries for it in his chest. (Batteries were shit like 15 years ago.) He was hyped about it, and I’m sure whatever he had was pretty rudimentary by today’s standards.

Once the electrode was in place and we performed the stimulation, the first patient immediately said, ‘I feel my legs.’

Even if the return of mobility is very minor, I would think the ability for a paralyzed persons to sense their immobile limbs would be a huge win for health.

This is super cool!
