MedFilter: Is there any reason why, with an enriched blood supply attached, a severed head couldn't be kept alive? If so, could it be kept alive beyond typical life expectancy? The only worthwhile attempt at an answer I can dig up is this, but I imagine this question comes up in med school quite a lot.. (There is a particularly kookie book called If We Can Keep A Severed Head Alive.. on this topic but it's generally regarded as 'nut literature'.)

A guy named Dr. Robert White did an experiment in the 1970's (see here and here) in which he transplanted a Rhesus monkey's head onto another Rhesus monkey's body. His ultimate goal was to make such a thing possible for humans to extend the lifespans of quadraplegics (whose most common cause of death is multi-organ failure). Not to give them a body which worked, but to give them a body whose organs worked (immobility is the cardinal cause of organ failure in para- and quadraplegics), White couldn't address the immobility issue, but he at least was looking at extending lifespans. I've seen footage of the monkey head experiment, it was pretty creepy, but done in a good cause, I guess. I believe the transplanted head lived for several days.

Back when the Loompanics catalogue was as thick as a phone book it offered a book claiming that the U.S. Gov't had experimented in this area and actually kept a severed head alive and conscious in a secret laboratory basement somewhere. It sounds nutty and probably isn't true, but then again there's that law that says that if it's remotely possible it will someday occur (and my own similar belief that keeps me awake at night, that if it's remorely possible, some gov't somewhere will try to commit it on a person or animal in the name of "research").

Of course, I don't believe the disembodied head story, thank God, but on a theoretical note, wouldn't a disembodied head die from the utter physical and emotional shock of the experience? Is it possible to die of fright alone?

All of this is even supposing a machine could actually provide and maintain the immensely complex chemical balance that the human body does. It's my understanding that there is no machine as complex as the human body and brain and never will be...

See? biscotti posts at the exact same time as I do, confirming my theory that if it can be imagined, researchers will try it.

I'm assuming the experiments were never a practical success, and the monkey went mad in the process. Personally, I'd gladly accept the inevitability of death before I'd ever want to undergo such a procedure...

Good intentions or sensationalist, unimaginable, sadistic cruelty committed on an innocent animal? Jesus. The human goddamned species...

Though it's been dismissed as a hoax, this alleged Soviet film shows various animal reanimation experiments, including keeping a severed dog's head alive and receptive to stimuli. (Warning: not for the faint of heart)

Here's a little Wired article on recent developments.
and another review of the "If we can keep a severed head alive..."

Seems like official primary thing holding back the whole process is medical ethics. There are quite a few people (neurosuspensionists) gambling that this technique will become possible in the future.

Mrs Shelley meant it to be a cautionary tale.

I don't know about the US Government, but the monkey head was most definitely alive and conscious (unsurpisingly, it tried to bite people). Poor monkey.

It doesn't have to be a machine to keep the head alive, a vat-grown human body genetically engineered to be anencephalic would do perfectly (chop the old head off, sew the new head on), and would undoubtedly be cheaper and more effective than any machine.

As to dying of fright, assuming the head had come from a body so damaged as to be unfixable, I see no reason why the head would mind (ha) being attached to a new body. If it came from a perfectly healthy person kidnapped by black helicopters and Men In Suits and whisked off to Area 51, though...

I'm assuming the experiments were never a practical success

Actually, I believe they were considered quite promisingly successful, but further experimentation was stopped by animal welfare movements.

Right, like I said ;-)

(Heh, biscotti, that's two jinxes we posted at exactly the same timestamp in just 9 comments!)

Give me a natural death any day. I'll never be anything but a Luddite (and an animal right's activist) on this one.

Steve Martin already proved that brains can be transplanted, so why not heads?

It would be even cheaper to vat-grow one wicked-fat anencephalic body* with a whacking great blood supply and sew heads onto it wherever rich blood supplies near the skin. One to replace the original head and one on each femoral fer sure. Maybe a couple more in the armpits? Would those be cheaper coach-class accommodations?

Or I suppose you could just chop off the arms and legs and stick heads on the stumps if you didn't want to expend the energy to keep the arms and legs alive.

Could you hook up another few heads direct to the aorta, or would that just mean instant hemorrhagic death from the pressure?

For similar ideas, see the Greg Egan story "Appropriate Love" or similar-title.

*Or, as it would inevitably be known, Mega-Keanu.

But you have to think of the consequences
posted by Capn at 2:11 PM on July 15, 2004

A number of problems have been touched on:

You'll need an intact carotid sinus (and aortic sinus less so) to maintain normal blood pressure.

You'll need correct levels of oxygen and glucose, as well as amino acids.

You'll need lymphocytes, macrophages, and a number of other immune cells to prevent infections.

You'll need regulatory hormones from a multitude of organs.

Plus a number of other things I'm not even thinking about right now.

Just an aside, on the subject of Mary Shelly: I live across the street from the main office of the California Department of Education in Sacramento. In the lobby, in large letters on the wall above the security desk, is the following quote:

It was the secrets of heaven and earth that I desired to learn....
-- Mary Shelley

Which really, seriously makes me wonder if anyone who works in that office has actually read the damn book.

I think the biggest issue, once you take care of blood, hormones, etc would be the lack of a nervous system. You're cutting off the spine at a very high point and eliminating the feedback your brain has been "listening" to since day one. This probably would have severe effects on the person.

Although, if you kept enough of the spinal cord you could probably deal with this problem.

That's, of course, ignoring the psychological issue of being without a body, which seems to be the real catch.

Holy crap, thats one freaky video. Dog kept alive by 30's technology. Its like someone had a spare sewing machine and thought it would make for a great experiment.

How is this a hoax? Looks credible and keeping blood pumping and organs working at that time wasn't some great mystery.

One person claims its a hoax, others say its real, and one site mentions it might have been faked to fool Americans.
