Now heart transplantation is possible.in future brain transplantation is possible or not?

Answer 1

Brain transplants are not currently possible, because nerves are tremendously sensitive to damage, and you can't really replace a brain largely because it would involve severing innumerable nervous connections (synapses), the vast majority of which will not reestablish properly within the new body. Every axon forms tens-to-hundreds of synapses with effector neurons or organs, all of which must be intact for the nerve to function correctly. Even only-partially damaged axons are unlikely to travel down their appropriate, convulted path after injury, resulting in non-functional nerves -- this same concept applies to brain transplants, as most axons would not reestablish appropriate and functional synapses, leaving the patient with severe neurological deficits.

Answer 2

Highly unlikely. Since neural tissue, tissue in the brain and spinal column, cannot regenerate, a means will have to be sought to establish a connection from brain to body. The most likely candidate for this would be to use a stem cell based treatment to bridge the neural gap between brain and body. Aside from the ethical issues inhibiting stem cell research, the brain is still poorly understood in terms of function. Until all functions of the brain are mapped and understood, it us unlikely that brain transplantation will be feasable. Furthermore, it is very unlikley that a suitable "body donor" would be found, as a suitable body would need to have all bodily systems healthy and in working order, with the exception of the brain. Heart transplantation is made possible because people who meet untimely deaths may not have damage to the heart (i.e. death as a result of head trauma), making the heart suitable for use in another human being. As said before, brain transplantation would carry the prerequisite that a sound body without a sound mind is found... which is certainly possible, but rare.

Aside from all of these problems, the biggest problem that a brain transplantation would meet is one of ethics. For obvious reasons, the transplantation of ones mind into anothers body would be a highly controversial issue, and one that probbably wouldnt be well recieved by the AMA.

Answer 3

Probably never. You'd want each individual axon to be connected at the cellular level with the remaining part of the exact same axon on each of the cranial nerves and the spinal cord. As it stands, transplanted hearts don't work the same as the floor model, because we have the vagus nerve regulating our hearts, and it can't be reconnected in a transplant. This actually has clinical significance. People with dangerously slow heart rates are often given atropine to speed the rate until an electronic pacemaker can be placed. That won't work in a transplant patient.

Answer 4

The problem with brain transportaion is you literally would not be yourself witha new brain most especially a foreign brain. A person would have to live long enough of a life to "watch" their past experiences their original brain had but then again that would even be from the persepctive of a new brain so its really complicated and I believe while it could be possible the only feasible method of doing this in the future would be to somehow record and send the images to the new brain, but now that I think of this it is totally unethical and I firmly beleive when it it is our time to go, its our time to go and we should not even think about trying to play God to escape death. It is not wise to "store up treasures on Earth where moth and rust can destroy."

Answer 5

my be it will never happened in future.brain is so complicated thing do u know that how patient suffer when any transplantation occur in his body.and during trnsplantation how many test performed now u think that if brain transplantation occur hw many test performed.u just thimk that brain is connected with every system then we have transplan a brain r u imagene how much arteries,veins are connected.every arteries and veins possess different antigens.we have to match with new brain is it possible?i dont think so .

Answer 6

Medicine is advancing with every day that comes. Who knows that one day well see the new brain transplant procedure.

Answer 7

of course! several years back, transplantation was not even possible. with the advancing technology and endless pursuit of knowledge (which is what medicine is also about), brain transplantation will be possible.

Answer 8

i Dont think it is possible. brain tissue is vurnarable and causes irriverable damage by trauma. so the body cant re produce them. so when surgeon will handle brain it will loose it many cells which will never come back. so it is not possible as per todays science.

Answer 9

I surely hope not.My granny says and believes,the brain is where our souls are kept,Therefore God will not give man the technology to replace our souls.That's what my granny says..

Answer 10

nothing is impossible.

mankind has discoverd so many things and there are still many secrets to be unveiled/rediscoverd and established.
