How long does the consciousnesses last after biological death?

How long does the consciousnesses last after biological death? Some scientists in England think they have discovered the answer.

Are you a believer in cognizance after death?

Depends on how you define "death" but as far as I can tell the evidence strongly shows that the mind is what the brain does.

Actually these people weren't dead which is kind of why they are around to tell their tale. Calling someone "dead" just because their heart has stopped doesn't necessarily make them so. They are dead when they fail to wake up.

People in vegetative states fail to wake up, too, John Hardy not a Turnbull fan​. Are they dead?

No they certainly aren't. I'm just pointing out the sloppy use of the word "dead". Death isn't when the heart stops, death occurs when life ends at the cellular level and not a moment before.

Yes, the operative word there being "irreversible".

You said life ends at the cellular level. So which is it, when the cells cease to function or when "it's" irreversible? And what's "it?" Consciousness? We already discussed that. The heart? Can the brain function without the heart? Absolutely. So, when is death?

Death occurs with the cellular death of the entire brain including the brain stem. The irreversible part comes in because death is a permanent state of affairs. You can't resuscitate the dead.

Anyone undergoing any other experience, even if they are declared "technically dead" is not actually dead and actually not even close to dead. Death is a one way ticket, an event of thermodynamic finality.

Looks like interesting research. Whether the brain can be brought back to a functioning state after all activity has ceased is questionable. It would be hard to imagine that severe brain damage had not also occurred. None the less, the cells are still very much alive in a brain death scenario.

However, although brain dead humans are technically no longer alive, their bodies can often still circulate blood, digest food, excrete waste, balance hormones, grow, sexually mature, heal wounds, spike a fever, and gestate and deliver a baby.

"Technical" definitions used in common speech are rarely definitive.

So, I asked Andrew Tamm, who filled my Stream with a hundred (sarcasm there) animated gifs and cat pictures to remove me from whatever Circle he has me in where he posts the animated gifs and cat pictures. It was either that or unfollow him and I didn't see any reason to unfollow him. Me asking https://plus.google.com/112885755521259735422/posts/78dwnvvgh4p <==edited to add the correct link Then he plusses me onto Public posts of animated cat gifs : https://plus.google.com/u/0/112885755521259735422/posts/EuuR1tnU3vJ https://plus.google.com/u/0/112885755521259735422/posts/8r6Grcm2Jpj https://plus.google.com/u/0/112885755521259735422/posts/74PgSu6iL2s Then one of his friends (or Circlers) starts plussing me into posts of animated cat gifs : https://plus.google.com/u/0/107120198886093172821/posts/gRW9JhWLs5T Don't get me wrong, I'm all about sarcasm and messing with people, but this seems sort of childish to me.

I'm shutting down Google+ for the night and quite possibly for the weekend. Why? This stupid #gifwars thing people are so proud of. This Adam Black guy said he doesn't like gifs and now everyone is mass trolling him. Having been mass trolled like this I can relate to him easily enough. Have an opinion and the collective might of Google+'s lower class denizens jump on a bandwagon. I just saw a post where someone wanted to jump on board and had to get clarification she was tagging the proper Adam Black. She wasn't even connected to him ! Nor was she a part of the original discussion. She just wanted to follow the herd. When I called her out of it she claimed, "one gif doesn't make a troll." Perhaps not, but she's contributing to a larger troll effort. One straw doesn't break the camel's back, but thousands will. So, tonight, Google+ disgusts me. It probably will tomorrow as well. And possibly Sunday. I gave up Google+ for two months this spring
