Brain death is the irreversible end of all brain activity (including involuntary activity necessary to sustain life) due to total necrosis of the cerebral neurons following loss of brain oxygenation. It should not be confused with a persistent vegetative state. Patients classified as brain dead can have their organs surgically removed for organ donation.
Brain death, either of the whole brain or the brain stem, is used as a legal indicator of death in many jurisdictions.

Peace lies indeed.”
