Mike is correct. Brain activity does not screech to a halt but peters out
over a period of minutes once the heart stops beating.
When we (I'm in the medical field and not, by any stretch of the imagination
an engineer) speak of someone being "brain dead" or "flat line EEG," we
don't really mean that there is no electrical activity in the brain at all,
only that there is no purposeful activity.
That is why, in most jurisdictions--not all--death is defined as cessation
of heartbeat. In the eyes of the law, that's a dichotomous variable; it is
or it ain't. Which means, from a legal perspective, at least, that when lay
people say that so-and-so was dead for a time and then brought back, they
are correct, cornball as it sounds.
Actually, heart beat doesn't cease like snapping a light switch but trails
off into meaningless blips and wiggles that can go on for a while.
Clinical death, to physicians and other health professionals is when the
machine has quit and it can't be fired up again. Vague, yes, but perfectly
So.....I see no way in which one could determine with precision when life
ends. At least not with the precision that this group would consider even
