I’m sorry but you read wrong you absolutly can feel/look for brain function that is EXACTLY how the determination of brain death is made. Cranial nerves are assessed by checking for pupil constriction to light (2 & 3), doll’s eye reflex and/or calorics (8,3,4 &6) corneal reflex (5&7) and fiannly apnea test.
Absolutely no other scans are required (nor routinely done)under US law and I’m fairly certain Israeli law as well.
The heart can last without a brain as Sam2 pointed out. That experiment was interrupted since it successfully proved the very point you are now denying. (the sheep gave birth to a live sheep 2 days after its head had been severed)
However please note this isnt a discussion about brain death. That has been debated ad nauseum though I am more than happy to discuss it further on another thread.
My only point is this girl, tragic as it may be, is by both legal standards and medical standards dead and not simply “in a coma”
(I suppose she can be described as “appearing to be unconscious” just as Lenin can.)
