This awesome.  But we need to test the efficacy for a longer period of time so as to ascertain its effectiveness and use.

Dr. Quine, thanks again for the helpful comments. Human trials are next on the agenda for the researchers, but they will--as you observe--require many more connections, some of which will provide feedback. The proof-of-concept in rats was just to see if their technique would work. And their first human trials will not attempt to replace the entire spinal cord. However, their ultimate goal is to do just that. Thanks again for you helpful observations, I'm sure the researchers appreciate them too.

Yes, I agree completely. The researchers say it took the rats two weeks to "rewire" their muscle movement "intensions" to use the new neural pathway. Thanks again for your careful reading.

jnissen: Thanks so much for reinforcing Tony's pointing out a single character error in the last paragraph. As I told Tony, its hard to find errors that spell real words, since the spell checker doesn't find them and our proofreaders were out yesterday honoring Dr. King. Thanks again for the careful reading and helpful comment.

Tony: thanks for pointing out the single character error in the last paragraph. Its so hard to find those errors that spell correct words because the spell-checker doesn't find them. You need a real life proofreader and our were off yesterday honoring Dr. King. Thanks again for helping out.

But... these neural stimulators go to eleven.

An alternative paradigm: Wireless

The hard part of curing paralysis is picking up the intention of the patient, successfully implementing it at the muscle, and receiving suitable proprioceptive feedback. Getting a wire from the head to the limb is the easy part. Indeed, if the issue is problems with bodily rejection of the ribbon cable, the wire could be left out. A signal could be sent wirelessly from the top of the body to the bottom of the body. Implants of control devices (e.g. cardiac pacemakers) for extended periods of time have been achieved for years.

How Many Connections Needed for Minimal and Ideal Cure?

A cure for paralysis is one of the key goals of rehabilitative medical research. As such, news of cures attracts a lot of attention - and inevitably the headlines are over optimistic in anticipating the results. Positive short term results in rats hardly constitute a human cure. That said, I observe that the shown circuit provides 4 connections at the far end. How many spinal connections to each leg are needed for minimal and ideal cures? Basic abilities to lift and bend legs would provide significant benefit to a paralyzed individual. Better, the individual would have the ability to achieve a walking gait (this will probably require proprioceptive feedback to achieve balance and detect an uneven substrate). Ideally, all of the connections through the spinal cord would be restored restoring fine motor control to the foot and leg.

Locus is working with professor Grégoire Courtine on the project and hopes to expand its scope to treating epilepsy, pain management and Parkinson's disease.

While your at it... helps to spell the researcher's name properly!
