the human brain the body's most important organ but also the organ we know the littlest about it helps us to think two cents to feel that helps us to know that we are alive but coming with the fact that it is the most important organ it's also irreplaceable if our lungs liver heart or kidneys fail us there is usually some hope that a transplant can save us brain transplants however seem to only be long in science fiction but what if you could have a brain transplant one of the rest of your body was dying and all your brain needed to do to survive was abandon ship what would happen once your brain woke up in a new body the idea of reanimate the dead is not by any means a new idea in eighteen 18 Mary Shelley introduced the world to Frankenstein and the idea of what it might be like to bring a body back to life with an entirely new mind the result as far as the novel goes brought us something less than human with the creation frankenstein's monster responding to words such as creature monster and it even today the idea of conducting a brain transplant is considered controversial with critics arguing that the procedure challenges the very idea of consciousness itself even with moral objections firmly in place hasn't exactly discourage scientist from exploring the possibility of a brain transplant however transplanting human brain doesn't exactly exist outside of fiction but that doesn't apply to animals one of the earliest known experiments was done by Vladimir democrat a Russian scientist who experimented with head transplants creating briefly living two-headed dogs later in the nineteen seventies American surgeon dr. Robert White transplanted the head of a monkey on to another's headless body although this was not whites first attempt at the controversial procedure it was one of his more successful ones with the monkey being able to use it senses until its immune system rejected the foreign head and killed the animal a little over a week after the operation there have been no documented cases of a brain being transplanted into another body however this full head transplant is a lot more likely a lot more obtainable while white was never able to do more than a few briefly successful head transplant Chinese doctor shopping ran has attempted to find the secret behind the tricky operation by 2015 redhead created over 1,000 hybrid mice by removing and switching their heads after the ten-minute operation the mice will be able to breathe move blank and even eat on their own using tiny tubes that carry oxygenated blood from the brain to the new body the mice would live tragically short lives dying only a few minutes after the operation was complete rain believes that his research though unsuccessful is the key to understanding how to one day successfully operate on human spinal cord however many of Rennes critics hope that day never comes dr. hunt Batjer president-elect of the American Association for neurological surgeon said I would not wish this on anyone I would not allow anyone to do it to me as there are a lot of things worse than death or could he have meant by that how can a brain transplant possibly be worse than death is he just simply trying to discourage medical advancements or is there possibly a colossal downside lurking in the shadows although experts cannot say for certain it is widely speculated that if he were to transport a human brain into another body the identity of the new body would be long to the donor of the brain however some also believe that the shock and disorientation caused by the aftermath of the surgery could continue to alter the personality of the brain donor creating an entirely new person if a brain transplant resulted in the creation of an entirely different person couldn't that also be considered a form of death and how would this kind of operation impact loved ones on both sides of the issue how does the family react to their loved one looking entirely different or how the grieving process be changed if their deceased loved one woke up and could walk and talk but no longer had the same mind no longer had an interest in associating with their family anymore perhaps this idea of personhood comes from the fact that we know very little in regards to how the brain works while we do know that the brain is deeply interconnected containing all of our bodily actions while still taking cues from the rest of our body as well as the world around us and interpreting them we don't know much about how the brain stores our memories as well as what it means to be conscious but as the brain the only thing that holds our personality and makes us who we are one theory known as the cellular memory theory challenges this idea that theory speculates that human body cells contain clues to our personalities taste in history's independently of either our genetic code or our brain cells so in theory the recipient of a donated organ may be susceptible to inheriting some of the personality traits of the donor while the theory has not been proven to be 100% validated some scientists and physicians are testing these ideas one organ that is thought to be prone to sell memory is the heart in Vienna Austria 47 heart transplant patients were examined over a two-year period and while the majority said they experienced no mental repercussions following the surgery 15% did say they experienced a noticeable change in their personality while six percent said that they could undoubtedly confirm drastic changes in their personality or no explained reason apart from identity surgery such as brain transplants can raise more questions such as those over ownership for instance if the transplant were to be successful in a male patient and they were later to have children with those children be biologically his just because the identity of the person changes doesn't mean that the makeup of the rest of the body does bioethics and regenerative medicine expert doctor christopher Scott speculates that not only would the body not truly be the recipients but that neither brains nor body would belong to either party the question posed was is this a person that the body belongs to or the person the head belongs to it is a chimera hybrid person even if you were to survive a surgery with your identity still intact will your sanity be intact as well some in the medical field believe that even if a head or brain transplant work possible creating moving breathing talking wife the effect the experience would have on the mind could be devastating and considering that those who do experienced traumatic experiences are susceptible to changes in their brain including ships and intelligence emotional reactivity happiness and sociability at best the mind may be altered forever at worst the person goes insane dr. Paul Myers associate professor of biology at the University of Minnesota has explicitly been against such procedures largely because of the potential effect it would have on the health of the mind doctor meyer stated confidently that even tasks were feudal the result would be at best a shambling horror and animal driven mad with pain and terror crippled and whimpering even if the transplant were possible similar issues that could be faced during and after the procedure can be seen in one of Sciences latest miracles face transplants levels of anti-rejection medications required for the procedure are so high that they put patients at risk for cancer and kidney issues patients also have a hard time getting full function of their new face making the idea of a much more complicated brain transplant even more of an improbability so with all that being said brain and head transplants are far away right while not as far as you might like to think in 2015 Italian surgeon Sergio Canavero announced that he would perform the first ever human head transplant removing the heads of two bodies and rejoining them to the opposite bodies Cannavaro plans to remove the head of a living person with a dying body and attaching it to the body of a recently deceased person whose body is in relatively good health the operation costing over 16 million american dollars would call for over 36 hours of surgery requiring a team of over 150 medical professionals 80 of them being surgeons to remove the head and fix it onto a new body in order to perform the surgery Connemara would need to cool the body to a low temperature 10 degrees Celsius to be exact before decapitating and reattaching using the nerves of the spinal cords with a small electric shock and a substance called PPG afterwards the patient would be placed in a coma for almost three weeks to reduce muscle movement followed by months of rehabilitation some of it possibly under virtual reality in order to have the patient acclimated to their new body the severe mental strain from waking up in a body you have never used is a dangerous proposition after all despite the hefty price tag on the harsh criticism surrounding the Italian doctor Canavero has already found a subject Russian graphic artist Vladimir Spiridonov Spiridonov suffers from severe muscular dystrophy causing him to have been bound to a wheelchair all of his life if the surgery goes well it will be the first time the 31 year old has ever walked due to the controversy surrounding the operation the procedure will take place in China with Canavero hoping for it to happen as early as 2017 so are we likely to see a full brain transplant in our lifetime no we're not however bullhead transplants are potentially possible however who knows exactly what we're going to see who knows what's really truly possible however there is one fact of course is that possible doesn't mean ethical concerns still surrounding some transplants while others are now considered common our perception of what is natural and should remain uninfluenced by man continues to blur in change but the facts are that transplants have saved countless lives a successful one offers a person a more fulfilling life allowing those who would have otherwise surely died and escape from the threat of premature death but one perspective believes that while delaying premature death is OK delaying it at all costs sometimes at the possible sacrifice of quality of life is a crime against nature reanimating a dead corpse is like people playing God but aside from moral objections think of what a successful procedure like a brain transplant could do for some of our greatest minds although brain transplants wouldn't allow us to be immortal by any means of the brain ages like any other organ the procedure would allow geniuses to continue their work and continue changing the world for the better imagine in what ways the world might be different if Albert Einstein lived another 10 years well perhaps this isn't the best example when offered surgery that would have possibly saved his life he actually turned it down and said I want to go when I want it is tasteless to prolong life artificially I have done my share it is time to go I will do it elegantly and he died the next morning but aside from geniuses imagine all the people that it could help and escape from cancer not a cure by any means but it is another option and now is the point where I questioned you I asked on my Twitter if a brain transplant work to be 100% successful guaranteed and full consent was given by both parties do you agree with the idea of transplanting one persons living brain into the dead body of another person 3385 you voted 34% said that brain transplants are acceptable under any circumstances 27 percent said that they are unsure another 27% said that brain transplants are acceptable only as a last possible resort for survival and all other options have been exhausted and the remaining 12% said that it is never an acceptable option and that it is unethical be sure to follow me on my Twitter @TheRobDyke to cast your vote in my weekly question everything poll so what do you think are brain transplants an exciting step into the future or is it just another way that humanity is going to play god and lose be sure to leave your thoughts in the
