PVS a Myth?

This is big.

In a study certain to rekindle debate over life-sustaining care for those with grievous brain injuries, researchers report that five patients thought to be in a persistent vegetative state showed brain activity indicating awareness, intent and, in one case at least, a wish to communicate.

Of 54 unresponsive patients whose brains were scanned at medical centers in England and Belgium, those five appeared able, when prompted by researchers, to imagine themselves playing tennis, and four of them demonstrated the ability to imagine themselves walking through the rooms of their homes.

Caution: human lives at stake.
