Brain implanted electrodes has brought consciousness back

Sometimes, technology does some wonders. For this man, he has been in "minimally conscious state" which is very close to coma or vegetative state. He has been in that condition for 6 years, feeding on a tube into his belly.

After the brain implant electrodes were implanted into his head and researchers turned on and off the electrodes over six months and reported that it became effective for this man. He is able to chew and swallow instead of using feeding tube.

It looks very risky by looking at that picture, electrodes going real deep into the brain. But with man in "almost" vegetative state, it surely worth to do that kind of research work! If you disagree with that research process, is it worth for man to stay in "almost" vegetative state for the rest of his life? What if Terri Schiavo had that implanted, would she be successful? Her parents believed that she was not in vegatative state, but her husband did.
