Dave (tam), it's nice to see you here again. In the case of Terri Schiavo, there is not much left of her brain, mostly just the stem and a lot of spinal fluid filling the space where the rest of her brain used to be. The doctors who have been involved with this case for many years have said that she is not reponsive. The little bit of footage you have seen is just about all there is among the many hours of footage that exist in which she doesn't just blankly stare off into space, and the doctors have determined that what looks like responsiveness in the footage you have seen is not what it appears to be. That is why the state she is in is called "persistant vegetative state". The only brain activity they have been able to detect is what is required to keep the heart pumping and other autonomic nervous system and reflexive activity.

I am sorry to read that your daughter is having to be fed through a tube. I don't know the circumstances you and your daughter are facing, but I wish you the best of luck with everything, and my best thoughts and wishes go to you and your family for whatever help and comfort you and they need at this time.
