Does Life Flash Before Your Eyes? Brain Scan of Dying Man Suggests It's Possible (theguardian.com) 42

When Harry Stamper sets off a bomb to save planet Earth in the film Armageddon, his life flashes before his eyes. Now research has revealed tantalising clues that such recall may not be Hollywood hyperbole. From a report: An international team of scientists has reported an unexpected situation in which they recorded the brain activity of an 87-year-old patient as he died. The man had been admitted to a hospital emergency department after a fall that resulted in a bleed in the brain, and subsequently deteriorated. When doctors carried out an electroencephalography (EEG), they had discovered the patient had developed epilepsy. However, during the EEG recordings he had experienced a heart attack and died.

The team says analysis of recordings of the 30 seconds before and after the man's heart stopped beating suggest that in his final moments he experienced changes in different types of brain waves, including alpha and gamma brain waves. The study suggests that interactions between different types of brain wave continue after the blood stops flowing in the brain. But, the researchers add, it also raises an intriguing possibility. "Given that cross-coupling between alpha and gamma activity is involved in cognitive processes and memory recall in healthy subjects, it is intriguing to speculate that such activity could support a last 'recall of life' that may take place in the near-death state," the team writes in the journal Frontiers in Ageing Neuroscience.

However, the findings are based on the recordings from just one person, and the researchers urge caution, noting among other factors that traumatic brain injuries and white matter damage can affect brain waves, while activity of networks in the brain can be affected by anticonvulsant medication such as that given to the patient. Nonetheless, the researchers say the results could have important implications.

    The experience that you are having right now, of reading this post, IS the experience of watching your life pass before your eyes. The present experience is one little slice of the grand narrative of your life, which is now passing before your eyes. Once it finishes, you will die.

    I've just been through this with my mother (not the death part); if your elderly folks hit their heads, such as after a fall, getting a brain scan soon* is important. Apparently about 10% have brain swelling which requires immediate attention.

    * Consult your doctor about the definition of "soon". Our medicos pressed to get one done right away (within hours, in her case).

      Not just the elderly. Young healthy folks taking a solid hit to the head and then dying of a brain bleed several hours later is sadly far from uncommon.

    The fact that the brain activity increased doesn't mean that it was related to any flashback events. In fact, the article makes it clear that these sort of brain waves relate to multiple functions, and then the author goes on to assume it was a flashback.

    The previous article said that they conducted the EEG after he died. Fifteen minutes later.

    With a sample size of one (1), this is meaningless gibberish, anyway.

  • In the near future, everyone will have their brain scanned after death. This will detect whether the person committed any unsolved or undetected crimes in life. Fines will be levied against the person's estate, or in cases where they are destitute, their family. Where the family is also unable to pay these fines, family members wi be transferred to labour camps to work off their debts.

    • Congrats. You just wrote the synopsis of a dystopian sci-fi novel. Now write the story and make your millions so you can pay your fines after you die.

  • As biased as my own analysis may be; what purpose would recollection during death serve?

    Are these last moments experienced as a frantic struggle to search desperately for any means to survive? Is this conscious in the sense of fore-brain activity or is it more animalistic?

    • If I were simply thinking pragmatically, it would be a great way to get memories replicated to other parts of the brain in case of brain damage. Death might be imminent, but any action that your body takes would be related to ultimately still surviving. A stroke would be an example where an oxygen deprived brain can get severely damaged in one area, but the rest of the brain may yet survive - it's possible a mechanism like this could salvage some data from the damaged part of the brain by rapidly recallin

      • That's a good take on this as a hypothetical!

        I prefer to view the system as a complex signal processor. Rather that obeying logical rules such as if (death == imminent) emergency_backup(); a deeper analysis of how the system from the context of signal processing could be forced into such a state. In that sense if (hormone > threshold) emergency_backup();

        This is a very plausible take in my opinion as a combination of stress hormones does trigger all sorts of high activity related to memory storage/retri

      • That's not how it goes. Our brains don't RAID stuff or do backups.

        Neither our brains nor our bodies give a flying shit about our masturbation memories from back in high-school. Or trivialities like our names. Or names of other things.
        Or that hard learned skill not to shit our pants whenever the lower part of our colon gets full.
        Or anything else that happened to be stored in the memory for a while.
        That's all just data files. And there are no system files.

    When you are playing the old analog VCR if you suddenly pull the plug, it sends out a really unusual burst of signals through the coax cable to the TV. I think the VCR flashes all the videos it has ever streamed at the moment of death. The TV too flashes incoherently, unable to display the torrent of videos properly.

    Yes, I think this is the most plausible explanation of what I had seen. Based in this research.
