The AP story has more details that Reuters.

“The new study used brain scanning called functional MRI, or fMRI, for 23 patients in a vegetative state and 31 diagnosed as minimally conscious.
Patients are diagnosed as being in a vegetative state if they are tested and found unable to do such things as move on command or follow a moving object with their eyes. (Their eyes are open; in contrast, comatose people’s eyes are closed.) Minimally conscious patients show signs of awareness, but they are minimal and intermittent.”
Again, it’s really moot as no responses were found in people with injuries like Terri’s.
The test was done on people thought to be in a vegetative state. Terri wasn’t in a vegetative state per your definition. Have you ever watched the videos of her? My point was that the media and people on this forum keep perpetuating the lie that she was PVS.
