In an Unexplained Case, Brain Activity Has Been Recorded as Much as 10 Minutes After Death



Doctors in a Canadian intensive care unit have stumbled on a very strange case - when life support was turned off for four terminal patients, one of them showed persistent brain activity even after they were declared clinically dead.

For more than 10 minutes after doctors confirmed death through a range of observations, including the absence of a pulse and unreactive pupils, the patient appeared to experience the same kind of brain waves (delta wave bursts) we get during deep sleep. And it's an entirely different phenomenon to the sudden 'death wave' that's been observed in rats following decapitation.

"In one patient, single delta wave bursts persisted following the cessation of both the cardiac rhythm and arterial blood pressure (ABP)," the team from the University of Western Ontario in Canada reports.

They also found that death could be a unique experience for each individual, noting that across the four patients, the frontal electroencephalographic (EEG) recordings of their brain activity displayed few similarities both before and after they were declared dead.

"There was a significant difference in EEG amplitude between the 30-minute period before and the 5-minute period following ABP cessation for the group," the researchers explain.

1. Makes one wonder

What were they thinking about for those 10 minutes?

2. From a previous article I had read:

The results revealed that 40% of those who survived a cardiac arrest were aware during the time that they were clinically dead and before their hearts were restarted. Dr. Parnia, in the interview stated: “The evidence thus far suggests that in the first few minutes after death, consciousness is not annihilated. Whether it fades away afterwards, we do not know, but right after death, consciousness is not lost. We know the brain can’t function when the heart has stopped beating. But in this case conscious awareness appears to have continued for up to three minutes into the period when the heart wasn’t beating, even though the brain typically shuts down within 20-30 seconds after the heart has stopped. This is significant, since it has often been assumed that experiences in relation to death are likely hallucinations or illusions, occurring either before the heart stops or after the heart has been successfully restarted. but not an experience corresponding with ‘real’ events when the heart isn’t beating. Furthermore, the detailed recollections of visual awareness in this case were consistent with verified events”.

I'm guessing that means if your eyes are open you may very well be dimly aware of some of the actions going on around you

4. Talk to an electronics engineer, not a doctor...

Just my guess--

Brain waves are electrical impulses commonly measured by such things as Hall effect sensors. I don't know, but would assume something like that is in an eeg machine.

The brain would presumably have capacitive effects with all of this energy flowing, and capacitors can take a while to fully discharge.

So, while the brain is "discharging" when the cells are actually dead from lack of blood flow, it would look like it was working.

6. That's a very good analogy

At the risk of being gruesome, I wonder if the discharging neurons would cause "flashes" of memories or even thoughts?

We will all find out someday but I'm not too curious, it can wait

5. The body is an ecology

Like any other ecology it does not die all at once. I read a fascinating book about the science of decomposition and one of the things they found is that cells die and stop working at different rates after "death" although it seems gruesome and a little creepy if you really think about it , it is kind of beautiful from a scientific process perspective..

This post will probably ensure that no one on this board who reads it ever speaks to me again LOL

8. Nahhhh....

I know what you mean by this.

One time I got someone really pissed off at me when I declared that hurricanes can be beautiful.. Well, photos of them from space, I mean.

"Waaaahhhh!!! WTF is wrong with you??? Don't you realize how many PEOPLE THEY KILL?????"

etc., etc., etc.


The person obviously didn't understand that I wasn't including thoughts about the damage they do. Just their awesome power and appearance.

Leave out the part about the damage, and they really are beautiful.

Anyway....

You can't make people understand...

9. Thanks

I just made my first Discussionist milestone by getting a post hidden. Does that mean i am part of the group now?LOL.

Anyway I happen to agree with you hurricanes and tornadoes and volcanic eruptions are beautiful.I love watching thunderstorms as well. The world is the world and its processes are neither good or eveil that is always in the hands of humanity....

7. The real question that needs to be answered is

can brain activity be detected in the SJWs?
