Before a diagnosis of brian death can be rendered, hypothermia must be ruled out. Since body temperature is regulated by the brain, this means that a functioning brain is one of the prerequisites for a diagnosis of "brain death."
At least some of the "brain dead" still regulate the body's electrolye balance, an activity mediated by the brain. The brainstems of some "brain dead" individuals register measureable responses to visual and auditory stimuli. And at least some "brain dead" individuals have activity in the cerebral cortex which can be detected via EEG's.
