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.

Famous quotes containing the words brain and/or death:
“I recently learned something quite interesting about video games. Many young people have developed incredible hand, eye, and brain coordination in playing these games. The air force believes these kids will be our outstanding pilots should they fly our jets.”
—Ronald Reagan (b. 1911)
“The child who enters life comes not with knowledge or intent,
So those who enter death must go as little children sent.
Nothing is known. But I believe that God is overhead;
And as life is to the living, so death is to the dead.”
—Mary Mapes Dodge (1831–1905)
