I apologize Twit for leading you astray on that video. Your last sentence is still correct however. Here is the REAL Dr. Cranford video that shows him talking to Terri and acknowledging her responses.
Investigating this, I came across numerous references to Dr. Cranford doing essentially the same thing in a different video -- with Terri being able to track visually. That is doubtless where the confusion arose. Incidentally, Dr. Hammesfahr criticized Cranford for issuing commands to Terri much too quickly. Brain-damaged patients process information slowly. Cranford didn't give her enough time. For all that, Terri did respond to both audio and visual stimuli from Cranford. Not bad for someone who's blind and deaf
It turns out that other brain specialists studied these videos and offered their professional opinions. I read several of their depositions saying that Terri was responsive and showed some higher mental function, and that she was not PVS. There are many more to read. I think I should quote some of those, but not now.
I'll get to your video shortly. Thanks for posting it.
Dr. Cranford gives her a voice command, though she can't hear, to follow a light with her eyes. But this woman is blind! Does he think she can hear and SEE? It is batty.
"...You see that, don't you, huh? You do follow that a bit, huh? ... OK, that's good!"
Give it up if that's the best you have -- even the autopsy confirmed she was blind. You fanatics are something else. Faced with facts, you still deny it.
