A lot of potential for both good and harm with a procedure like this. I remember a couple years ago reading about a Russian guy with muscular dystrophy volunteering to transplant his head, but I guess it never followed through due to the ethical and safety concerns. I wonder who could even consent to donate their body for this type of procedure?
I saw a video where a guy was going to volunteer but then he got married & no longer felt the need to. I guess people in that situation are only willing to risk their life if they don't see a reason to live.
Yeah he stopped volunteering, his condition stabilized, he got a really gorgeous wife who was also a scientist and is finding happiness despite his disability which is amazing.
I attended a lecture given by Dr. White to an audience of physicians, so the subject wasn’t watered down. The protocols he developed were explained in detail, as were the obvious limitations due to the spinal cord having to be severed. He was very personable, down to earth, and sensitive to all the controversy his work had stirred up. During the Q&A, he discussed all the young people who die from massive brain injuries every year, but with bodies intact, and all the patients with normal cognitive function but with terminal diseases affecting internal organs. When asked if further research might someday be conducted on human subjects, he stated that that wasn’t a choice for doctors to make, it was for the public to decide.
I’m a little surprised they didn’t mention the insect head transplants. Not only were they going on ever since the 1920s, but they are still successfully done today. For example, people have been doing decapitation and transplantation experiments on Kissing Bugs for at least 90 years now.
Ship of Theseus but not mind-body problem. The mind is not the brain. That annoyed me. But an interesting question would involve swapping half the brain in each subject. Or parts of the brain.
@@GizmoMalteseI assume some personality of person A would be mixed with person B and vice versa. Unlikely that their consciousness will be fragmented. Although, memories may be mixed up I assume.
@@GizmoMaltese Considering the brain tends to adapt when missing parts of itself i dont think there would be a mix of personalities, unless you got the conscious part of both brains, but isnt that always the left side? Could you make a brain out of two left sides?
I don't know why but after watching this I suddenly feel a phantom pain around my neck somewhere... Edit:- Wow! Over 70 likes! Thanks guys❤️ This is the most that I have ever got!
I feel very few people would be willing to donate their body in this way. And I’d wager very few people would even want their head put on a random person’s body (it’s not like you could pick from hundreds of bodies to select the one you like the look of best). It would be so dysphoric.
I like the idea that in case of a head transplant, neither organisms survive and a totally new one is created. That doesn't make too much sense, however it is a small loophole for the philosophical questions such a surgery could raise.
I've never thought of it that way. The living being resulting wouldn't be either the monkey A or B, but a quimera of both. Alas, given the extent of the experiments, probably that wasn't even the correct result. Apparently the head never got attached, and even if the other monkey's blood carried different hormones, which would've affected the head, I personally see it more like a life support machine, only made of wetware instead of hardware. Probably, if the nerves could've been spliced together, the resulting creature wouldn't have ever behaved quite like the monkey A nor the monkey B, but I don't know when we'll archive that level of medicine!
Okay, so if Monkey C is indeed a new creature, then aren’t you forgetting about the object permanence of the donor parts from monkeys A and B? Those don’t just blip out of existence now that the operation has concluded: Monkey A’s head continues on in this “new” creature, same as Monkey B’s body. The resulting patient of this procedure cannot both have a new body as well as a continuation of the donor body, it can only be the latter.
there is so much to love about this video both in terms of form and content but lemme just say the music is really great. It's straight out of a Yorgos Lanthimos movie
The subject matter plus the music made this the most chilling media I’ve consumed - book, movie, podcast, anything - in a long, long time. Love it! (And banning my toddler daughter from watching it. She is a huge fan of this channel.)
My grandma was White's assistant during the time of this procedure. She still talks about working with the monkeys, and the interesting logistics of having to schedule their flights into Cleveland.
@@asasipogi They both died as a result of the procedure. The one whose head was kept alive managed to live for 9 days until immune rejection happened. Just to be clear, I don't personally condone what was done. The whole experiment was very ethically dubious.
Preach pastor, PREACH. John Kennedy or Joseph Stalin or Eisenhower or one of those political figures could have destroyed the whole world with nuclear weaponry. They shouldn’t have, and they didnt
In response to the 'body w/mind vs mind w/body' quesion, I think there's a stronger argument for multicelular species being primarily single celular creatures living in complex symbiosis with one another.
I think the answer is somewhere in between, as with the case of neurons across the body, the heart has its own "mini brain" (intracardiac nervous system) which isn't as big as the main brain but certainly much bigger than you think. The brain has 100 billion neurons, whereas the mini brain has only 100,000. This means that the brain has a million times the number of neurons that the mini brain has.
I feel so bad for the monkeys, and the experiments are horrific and barbaric, but he really WAS trying to help people and I hesitate to paint him as a *complete* monster or anything like that.
Good thing, I'm at work while watching this (but is almost dark and raining really hard). The story telling and the bg music makes this video really scary.

The music was perfect for this. I'm surprised that the video didn't touch on the implications of making those who can afford it (reasonably and with respect to body aging) immortal.
2:56 "And how many animals would have to die to prove it was possible?" Is he not aware of the millions of animals we kill every day for food? That's just needless suffering. At least with this, something good might come out of it and help reduce human suffering.
Unfortunately for the ultrarich, full body transplants aren't the longevity solution they are so desperately after. while new bodies might be young, the brain itself is prone to the effects of aging very much.
I'm not sure how that works. Neurons don't undergo mitosis. That's why you can't get more of them (except in the hypothalamus iirc). And since aging involves DNA damage due to repeated replication, neurons are immune to this. Theoretically, if you could isolate a brain and provide it glucose and oxygen, it could live indefinitely.
@@feynstein1004 that's not what causes cell aging, there are basically two main causes that is now established to be the underlying cause of cell aging, one is telomere length which as you have mentioned is due to cell duplication, but another significant cause of aging is due to free radical damage from basically all the reactions that go inside the cell to sustain, overtime this damage accumulate and overwhelm the mechanisms that try to control it. This is why even though neurons don't undergo cell duplication many people at advanced age show signs of brain atrophy and even outright dementia
@@Decloren Ah yes free radical damage. I forgot about that lol. But that can be largely mitigated using antioxidants, can't it? The telomere damage is irreversible though. So I feel like my point still stands. Just that now the brain in a jar needs antioxidants in addition to the glucose and oxygen.
@@feynstein1004 It might have been possible but impossible to know since such an "antioxidant" that would prevent all free radical damage does not exist. Telomere length is an another topic since it is actually possible for cells to replenish lost telomere by the use of the enzyme Telomerase which is how stem cells and cancer cells can multiply indefinitely without issue
Doing a difficult abstraction of ethical considerations, I am sure it could work and I would not worry too much about the the body-mind interactions because it sort of is already partially experienced with cardiac transplantations! But the real challenge and main interest of this paradigm would be the next step with spinal cord reconnection and I think it's likely to be possible in a not so long future (20 years) with some new technologies working in the body for a few weeks after the operation : dealing with scare tissues, recognizing the main pathways for muscular groups and body functions with more and more precise targets, probably using millions spinal cord specific stimulations to recognize the correct path and get a connection with the new head. It would probably need many technologies like enhanced cells, surgery and nanobots, but the most useful side effect would be to allow recovery of most paraplegia and quadriplegia, by the way an excellent way to get research credits.
I wouldn't even say "nanobots" are needed, but just either a technological way to bridge the nerves together or working out how to do it biologically. From there, physical therapy might be a beast, though.
@@marsdriver2501 I suspect "no" but I'd rather know one way or the other definitively The reason I suspect "no" is that a lot of "muscle memory" is really just unconscious activities and the pathways are going to be different. Also muscles are gonna atrophy a bit while you learn how to control them correctly. It definitely will be a process getting functional again, but for many, it'd be worth it.
It would require something pretty remarkable because the neurons in your spine are really really long. Sowing them together wont work, you'd somehow have to attach axions together
@@Paul-A01 How does how long nerves are affect reconnecting them? No, that's irrelevant. The real issue is no good way to actually connect the ends in a way that actually works for the sheer number of nerves involved. It's basically akin to a bundle of individual strands of wires, each one having an insulating coating that all happen to be the same color.
I sometimes wished he was successful with this experiment. I have seen people who have the mind but not the body. I know it is ethically and biologically wrong but if the intention is to give a mind its body, then I think there is nothing wrong in it. I’m interested in this. My professor went through this just few weeks ago, I was the one who found it interesting.
It's scary, but it could really improve spinal cord injury research, because the spinal cord reconnection is the Holy Grail and not so much the head transplant.
This is terrifying. I'm having Ian Malcom's commentary of if science should do certain things and C.S. Lewis's :That Hideous Strength" going through my head with this video.
What kind of question is that? Our memories and consiousness are stored in the brain, period. It's like asking "am I the same person after taking medications, they change the chemistry in my body", interesting to debate but useless in practice.
It isn’t that ridiculous. We are our minds. But part of the self is our bodies. Muscle memory and all of that. How the body looks in your minds eye. Not matching up to what you see would probably be pretty hard to deal with. Your self is absolutely what your mind perceives as you.
@@XWierdThingsHappenX If you take it as a whole - sure. But the same can be said when you ride a bicycle - remember the first feelings? Like it's impossible to move? And then it becomes the extension of your body? So I stand by my statement. You are your mind. Everything else is secondary and can be adapted to.
@@Demetrius900000the thing they were referring to was the discovery of neurons in the stomach. We currently believe they are responsible as a sort of interface between the guy micro biome and brain, controlling things like cravings and nervousness. While much is still unknown, it’s accepted that it plays at least some role in influencing our conscious thought
@@nethascotx24 Influencing, so it's not part of our minds and memories. Just change the microbiome to old one or even a better one and you're set. My statement stands.
I'm inclined to agree with you but I'm nowhere near as certain. I don't know enough about this topic because I study chemistry, but the fact that we're learning more about how our body influences our mind (in the way that we're discussing anyways, there's the obvious way that it does) only leads me to believe we have much, much more to learn and any absolute statement is misplaced. tldr: I agree it's basically all in the head, but I disagree that it is a settled fact.
I understand that in order to fully understand what we are capable of we must push boundaries, but I fear the possibility of pushing a boundary that doesn't teach us anything.

But the real challenge and main interest of this paradigm would be the next step with spinal cord reconnection and I think it's likely to be possible in a not so long future (20 years) with some new technologies working in the body for a few weeks after the operation : dealing with scare tissues, recognizing the main pathways for muscular groups and body functions with more and more precise targets, probably using millions spinal cord specific stimulations to recognize the correct path and get a connection with the new head. It would probably need many technologies like enhanced cells, surgery and nanobots, but the most useful side effect would be to allow recovery of most paraplegia and quadriplegia, by the way an excellent way to get research credits.
I wouldn't even say "nanobots" are needed, but just either a technological way to bridge the nerves together or working out how to do it biologically.
From there, physical therapy might be a beast, though.
@@InfernosReaper I wonder whether muscle memory would still be present, I mean could person A have easier time relearning skills in a person's B body?
@@marsdriver2501 I suspect "no" but I'd rather know one way or the other definitively
The reason I suspect "no" is that a lot of "muscle memory" is really just unconscious activities and the pathways are going to be different.
Also muscles are gonna atrophy a bit while you learn how to control them correctly.
It definitely will be a process getting functional again, but for many, it'd be worth it.
It would require something pretty remarkable because the neurons in your spine are really really long. Sowing them together wont work, you'd somehow have to attach axions together
@@Paul-A01 How does how long nerves are affect reconnecting them? No, that's irrelevant. The real issue is no good way to actually connect the ends in a way that actually works for the sheer number of nerves involved.
It's basically akin to a bundle of individual strands of wires, each one having an insulating coating that all happen to be the same color.
I sometimes wished he was successful with this experiment. I have seen people who have the mind but not the body. I know it is ethically and biologically wrong but if the intention is to give a mind its body, then I think there is nothing wrong in it.
I’m interested in this. My professor went through this just few weeks ago, I was the one who found it interesting.
It's scary, but it could really improve spinal cord injury research, because the spinal cord reconnection is the Holy Grail and not so much the head transplant.
Honestly, if consent from both parties has been provided for this, it could be revolutionary
Why this music if you try to be impartial?
Maybe he’s not.
so now you're a new person basically after the surgery. That's like living two lives
Beautiful video❤️
I mean headlessness seems cool in fantasy but once this is put into perspective it raises a lot of questions.
I thinks it's a worth while and noble quest
No. It's a cruel thing to do
@@conniesmith8417 cruel to whom?
As a Kid I loved a book “Professor Dowell’s head” about an amputated head of a man living on its own. Turns out it wasn’t completely impossible.
Im traumatized.
What an absolute legend!
your scientists were so preoccupied with whether they could they didn’t stop to think if they should
This is terrifying. I'm having Ian Malcom's commentary of if science should do certain things and C.S. Lewis's :That Hideous Strength" going through my head with this video.
Well poor things did the opposite
I was hesitant to watch this video. But it kept popping and I watched it. It is going to haunt me forever now. 😅
Set yourself with an extreme ambitious goal to the point a little success can be revolutionary.
I think there is definitely a lot more scene of self in our bodies as well as our brains personally speaking.
Head transplants and little monkey fellas? Is Karl Pilkington editor in chief at Ted Ed?
Isn't the animation style also really similar to the Ricky Gervais Show or am I imagining things? I don't believe that this is a coincidence.
It’s not a head transplant, you still have the same head. It’s a body transplant.
What kind of question is that? Our memories and consiousness are stored in the brain, period. It's like asking "am I the same person after taking medications, they change the chemistry in my body", interesting to debate but useless in practice.
It isn’t that ridiculous. We are our minds. But part of the self is our bodies. Muscle memory and all of that. How the body looks in your minds eye. Not matching up to what you see would probably be pretty hard to deal with. Your self is absolutely what your mind perceives as you.
@@XWierdThingsHappenX If you take it as a whole - sure. But the same can be said when you ride a bicycle - remember the first feelings? Like it's impossible to move? And then it becomes the extension of your body?
So I stand by my statement. You are your mind. Everything else is secondary and can be adapted to.
@@Demetrius900000the thing they were referring to was the discovery of neurons in the stomach. We currently believe they are responsible as a sort of interface between the guy micro biome and brain, controlling things like cravings and nervousness. While much is still unknown, it’s accepted that it plays at least some role in influencing our conscious thought
@@nethascotx24 Influencing, so it's not part of our minds and memories. Just change the microbiome to old one or even a better one and you're set. My statement stands.
I'm inclined to agree with you but I'm nowhere near as certain. I don't know enough about this topic because I study chemistry, but the fact that we're learning more about how our body influences our mind (in the way that we're discussing anyways, there's the obvious way that it does) only leads me to believe we have much, much more to learn and any absolute statement is misplaced.
tldr: I agree it's basically all in the head, but I disagree that it is a settled fact.
That disembodied head looks like something straight out of _Gravity Falls._
Those poor monkeys! 😢 that's sounds so scary 😨
Yeah they should've tried with humans. Pussies.
It reminds me of the Soviet reanimated dog head experiment.
0:50 made me laugh, I'm sorry 😂
I think the unsettling music was completely unnecessary, distracting away from the ethical and scientific questions. Great video otherwise
I listened at 2 times speed so it didn't bother me.
I’m pretty sure that the music is perfectly well-suited for this video. It’s just as disturbing as the concept alone.
I understand that in order to fully understand what we are capable of we must push boundaries, but I fear the possibility of pushing a boundary that doesn't teach us anything.

Thank you for this information about the NIH.
DIO be like:
wryyy
Poor monkey, I can imagine the horror he felt when he woke up, not understanding what was going on
Kenjaku be taking notes
The thumbnail: ok.
The background music: nightmares
is that a jojo reference?
