So brain transplants are laughable ridiculous science fiction experiments that will never come true?

Well that's what 99.99% of the great scientific community was saying before this: http://www.youtube.com/watch?v=5JNmlqjLe4A


that keeping either of the brain or the body to be harvested alive during this process is impossible, yet it was done.


Now they say that it would be impossible and ridiculous because scarred nerve tissue does not heal and cannot be regenerated, and as usual they will find themselves proven wrong again.





The only true barrier to brain transplants that I can see is this 'scientific community' that keeps yapping about ethics and opposes anything new and revolutionary.So brain transplants are laughable ridiculous science fiction experiments that will never come true?
First, there is a difference between a brain transplant and a head transplant (either would probably be better described as a body transplant). With a head transplant you would at least be able to preserve sight, smell, taste, hearing, and ability to communicate (through blinking or face movement).





If you did a successful brain transplant by getting blood flow established from a different body you would have a very hard time knowing that it was successful as there would be no way to communicate and no easily appreciated brain output. I suppose the presence of EEG activity would be some measure of ';success';. If consciousness persisted it would be hard to assess and thoughts would almost certainly turn to madness in short order.





With either a brain or head transplant there would be no motor or sensory function below the neck, no voice, and no respiration. Maybe someday those can be at least partially overcome.





The ethics of performing the rather gruesome experiments needed to ';succeed'; are, at minimum, worthy of debate. Especially in light of the lack of any desire for current human application.So brain transplants are laughable ridiculous science fiction experiments that will never come true?
the only reason to transplant someones brain would be if you had two people one of whom irretrievably dead but with a working body and someone with an alive brain but a dead body such a patient would probably be in cardiac arrest hypothermic with extensive myocardial ischemia and peripheral tissue death however cardio-pulmonary bypass would most likley be required to prevent brain death and if a suitable donor could be found rather than take the whole body the most the patient would need is a heart transplant and amputation of the dead tissue meaning that the rest of the organs can be given to people who need them in short may be theoretically possible but will always be impractical
Dr. T-J is right.





Anybody who knows even the slightest thing about neuroanatomy and physiology knows that it's just not physically possible.





Somehow, I don't think that reality enters into your opinion on the subject, though....
Yes. More laughable and scientific community is open minded.
I don't tknow about that: I think I may have met some of the people where it didn't work.
its been done in the ussr
Yes ethics come into play, and so they should, however you don;t have a scientific background do you?





Central nervous tissue (brain and spinal cord) can not regenerate, this is why we have disability and why we are looking into stem cell research for the treatment of said disabilities and diseases.





This means that though you are able to stick someones head on your own and connect the blood vessels, there are too many nerves in the spinal cord to connect, and they will not regenerate on their own like peripheral nervous tissue does.





Maybe in the future if stem cell treatment works we may be able to trasnplant full human heads, however don't count on it happening in your lifetime, and again ethics will come into play - so they should. especially if stem cell research works, then no one will need a head transplant - as we will be able to regenerate brain/spinal cord tissue through the stem cells.





I think your just a hippie that needs to take some lessons in science, preferably degree level medical science before you start to question the community.
If this was actually true it would be headlines around the world. it is more likely that a tissue transplant would occur. If someone placed my brain in someone else's body it would have my memories - that person would cease to be who they were and would become me. Don't believe everything you see on You Tube - a lot of it is pure BS.





Transplanting a monkey's head is one thing - transplanting a human head with spinal cord linkages? Its news that they can transplant a face - transplanting a head is not technologically possible at this time. As to your statement that the scientific community ';keeps yapping about ethics'; I refer you to the medical advances of Josef Mengele - you need ethics in science or it becomes horrific. The scientific community does not oppose anything new and revolutionary, but the scientific community does demand proof and not just speculation. Welcome to science.
