Aprx a week ago there was an elderly woman who woke up in the hospital morgue. She had been identified as "brain dead" which was a shock to her...she was in a deep sleep.Both science and ethics asks the question "what is life"? What does it mean to be alive? Is that differant than fully alive?
You have the cortex which is responsible for higher thought and you have the brain stem which is responsible for breathing and your heart rate.
In my case, I had damage to the brain stem and could not breath on my own. But my cortex was functioning... yet I was not awake. Was I alive? Of course.--"good" EEG.
In Terri's case her cortex is damaged (higher functions) but her brainstem is functioning. She is awake. Is she alive? Of course.--no EEG
Christopher Reeve was in between the 2 states. He was awake, yet the brainstem did not function, but his cortex was ok. Was he alive? Of course. He would be identified as physically disabled.--"good" EEG (Steven Hawking would be another example)
A person who is mentally disabled but physically fit could have a damaged cortex but the brain stem is fine. Are they alive? Of course.--EEG "good"
On a side note, you can have someone with epilepsy that has a "bad" EEG. Are they alive? Of course. But there is a temp. disruption of the neuron firing.

None of these people are "brain dead".
To be brain dead (my understanding) is to have no functioning cortex OR brain stem.
But at the same time you can be in an accident, have your brain stem damaged beyond repair, your cortex fine..and still you are dead, dead, dead.
Thus, I think truly that the above examples are people who are a "little" alive. If that is possible.
Coma patients, people with epilepsy, people who are mentally disabled, people in wheelchairs, people on machines to breathe, all have brain damage of some type.
But our culture will eventually have to decide, are these people "alive" enough? The risk is that if you take one of these people and say "no", what is to stop the other people from being at risk of being determined as not fully alive also.
There are no clear answers here.
