Note that brain tissue doesn't regrow (at least in these mice). So nerve regeneration may be as yet out of reach.

Sorry about the Bobbitt double. I typed before hitting the 'refresh' key and didn't see your post.

If you regrow a limb, and can use it, nerve regeneration had to take place.

Remember, one of the experiments was severing the optic nerve. Apparently it grew back.

Tell that to those paraplegics with severed spinal cords who can now walk due to never cell regeneration. The docs use nasal stem cells. It takes about three years.
