Brain scan shows that vegetative patients can think - Britain - Times Online
I have recently criticised the type of research that MRI scans have used for (finding a "God spot" in the brain, for example.)
The story above shows a much more meaningful use - finding out whether a person in a vegatitive state has awareness or not.
Mind you, it may make withdrawal of life support decisions more difficult rather than less, but it's still worth looking into.
