Someone with a flat EEG is unable to perform even involuntary functions, such as breathing, digesting, circulating blood, etc., etc. It would be impossible to "starve" anyone with a flat EEG, as such a person would be unable to process nutrients even if they were provided.
That's not true and it's obvious you haven't read the court documents.
There are two regions of the brain and I've forgotten if it's the upper or lower regions which control breathing. Terri obviously is breathing on her own and it is the other region which is flat.
