Has anyone heard of PoNS? PoNS is a device that stimulates the tongue with an electrical impulse. I believe the idea is that it stimulates the cranial nerves and parts of the brain. Apparently it is undergoing trials. I don't intend to give anyone false hope, but it will be interesting to see how it plays out (especially in regards to balance issues).
It could be promising technology for some. However, we should all be skeptical of sensationalistic media coverage.
