Can a brain live for a minute after decapitation?

    I’m curious if the conductive nature of the blade matters. (think about the sensation of chomping down on aluminum foil)  Would a ceramic blade yield the same reaction?

  2. I knew this sounded familiar. It’s sooo Karl Pilkington: re: “a man who was beheaded and his body took 32 steps after decapitation…”

    Here’s another article at Damn Interesting
    I used to love this site but it’s been dead for awhile now, no pun intended.

    Awesome: we’re yet another step closer to Futurama head jars!

    My reaction has always been – why wouldn’t the brain be alive? It’s usually not directly damaged by the slice and only gradually ceases to function and eventually dies off due to lack of oxygen. You could be instantly knocked out by the shock and sensory overload, but you certainly don’t die immediately. The duration of the post-decapitation awareness could be anything from seconds to conceivably minutes (some theories state that the halted circulation allows the brain tissue to more fully utilize the oxygen content of the blood, but that is a mere speculation) and would probably considerably vary between subjects, but I am really convinced it is strictly a matter of “how long?” rather then “at all?”

      The brain may be alive for a short period, but consciousness is lost within about a second of the spinal cord being severed along with a complete loss of blood pressure as the arteries are also severed.

    Alive or not, it seems like a forceful decapitation would likely put you into shock (both the circulatory and mental kinds) so you’d probably be too dazed and disoriented to fully appreciate the novelty of being a disembodied head before bleeding out.

    This is probably one of those situations where “humane” and “aesthetically tasteful” are opposed to one another.

    There is, inevitably, going to be some amount of oxygen and already-generated ATP stored in the tissue of the severed head, and no physical disruption of the high-level brain areas. If you just dropped a big steel block, instead of a big steel blade, you’d get essentially immediate and massive physical disruption of the neural network. Much messier; but far less likely that the brain would remain conscious for any time thereafter.

    Can we get a Unicorn With Head Attached chaser?

  9. I seem to remember a program on one of the discovery channels about the French Revolution and a doctor or scientist who was ordered to the guillotine told his assistants to watch his head and he would blink for as long as he could…I think he managed to blink 17 times before not having any more control. Who knows how long it took for his consciousness to die completely.

    Why would we expect there to be a single moment that is a “border between life and death?” Death is a process. It seems to be that at what point in that process the organism is technically “dead” is a matter of deciding on arbitrary criteria.

    • Antinous / Moderator says:

      And yet, having watched a few people die, they do go from life to waxy lump of meat rather dramatically.

  11. Bevin says:

    I was with my Aunt when she passed on.  The family had made the decision to remove life support actually, and while the alarms were turned off, the monitors were on.  Long after she was “dead” there was still a lot of electrical activity being recorded, and it went on for a LONG time. It was beautiful and creepy.

    It’s been scientifically proven that a head can live separated from the body. Let me reference the following: “The Brain that Wouldn’t Die” – as well as the Academy nominated “They Saved Hitler’s Brain” –

    Is there a way to differentiate between cogent thought and a random jumble of reflex action using

  14. hypnosifl says:

    Wouldn’t the huge drop in blood pressure and quick decrease in oxygen supply to brain cells mean that you’d almost instantly go into a faint? (for comparison, a choke hold will make you unconscious in about 9 seconds, and in that case blood flow to the brain is only cut by 13%) There’s still brain activity in a person who’s fainted, but for all intents and purposes they are “unconscious”.

    Quick!  Get the soy sauce!

  16. Teller says:

    I recall reading that during the French Revolution, someone would lift the just-decapitated heads and laugh in their faces.

  17. Highly recommend Mary Roach’s “Stiff”, in which I learned that no sooner had the chopping started, then people were delving into this question of “is the head still alive?” .. and yes, the book truly is unexpectedly hilarious, fascinating and thought-provoking [ ]

    When I unplug my computers power cord, the transformer still has power stored in it (it’s fitted with an indicator light) for about 45 seconds; why wouldn’t the brain do the same thing, It’s all about electricity isn’t it? We don’t have to be robots to be electrified. 

    Or read Stephens Kings “The Breathing Method”.  

  19. bollesy says:

    This dumb thread, again!  The loss of sight and hearing would be nearly immediate with the traumatic decrease in blood pressure and hypoxia from O2 (blood flow has stopped) being rapidly metabolized by a brain running in overdrive. Yes, brain cells may well malinger for a while before dying but that wouldn’t sustain consciousness. And what about that two foot thunk into the basket. OUCH!!  Unless you talked Abhorson into letting you wear a helmet you’ve got another insult to “think” about. I’ve had the misfortune to have volunteered for a tilt-table test and if you’ve got orthostatic intolerance or syncope-BANG, lights out in mere seconds, even though your brain is getting a liter or so a minute from your heart frantically putting out 190+ BMP.  But I’ll be happy to hear your arguments if you’d like to conduct an N=1 non-replicable experiment.  Bear in mind you may have some trouble responding to the reviewers’ critiques.

    Just the title of this post makes me throw up in my mouth a little bit.
