Why Is Brain Death Important

Decent Essays
1. What is the definition of brain death and why is it important?

An organism dies when it loses the power to preserve and sustain its self-organizing organization permanently and irreversibly. This is defined as the irreversible loss of the capacity for bodily integration. Brain death focuses on the death of part of the organism, not the whole (body).
Upon further examination, standards published in 1968 suggest that brain death (aka "whole-brain") involves four essential criteria:
1) Lack of receptivity and response to external stimuli
2) Absence of spontaneous muscular movement and spontaneous breathing
3) Absence of observable reflexes, including brain and spinal reflexes
4) Absence of brain activity, as signified by a flat electroencephalogram
