This is incorrect. In a brain-dead patient, the isoelectric EEG serves to demonstrate the absence of brain activity despite adequate perfusion and absence of sedation, i.e, even though the computer is plugged in and you've pressed the start button, nothing happens, and thus, nothing is likely to happen in the future.

Isoelectric EEG can be induced with propofol and barbiturates, either voluntarily (refractory epilepsy) or involuntarily (anesthesia), without any obvious ill effects once the sedation is off.

Can you point to evidence where it is known if a brain can be restarted? Commenter said it's not known, you said it's untrue that it's not known, and stated that a brain can be made quiescent artificially or as a part of a neuralogical disorder and recover on it's own, but failed to provide evidence that we have a scientifically proven method to restart a brain.

I am not sure I understand the question. The brain "restarts" by itself if its otherwise normal and perfused.
