Is it possible to have brain transplant?
I made a bet with my friend. I said brain transplant is possible and he said it isn't. If I'm right he has to eat a glass full of cigarette ashes, mud, and worms. If he's right he gets to light me on fire while I do the Harlem Shake. Please help me answer this
Is a brain transplant possible?
Although many scientists have challenged the feasibility of this process, few would say that it was not possible given current research into organ transplant and human cloning. The bodies created for harvesting would have to be clones, criminals due to be executed, or as you said, people with fatal brain diseases. But the brain stem has to be severed, so one of the most significant barriers to the procedure is the inability of nerve tissue to heal properly; scarred nerve tissue does not transmit signals well (this is the reason a spinal cord injury is so devastating). However, recent research at the Wistar Institute of the University of Pennsylvania involving tissue-regenerating mice (known as MRL mice) may provide pointers for further research as to how to regenerate nerves without scarring. There is also a potential problem of the new interface at the spinal cord, in that even if all the nerves are connected successfully, they may not transmit the same information as the same nerve connection in the old body. For example, a nerve that used to control the right index finger's muscle group might be connected to a different finger's muscle group, or another body part entirely. If this were to happen to the majority of the connections, the person undergoing the transplant might end up with a body which transmitted sensory input to the wrong destination, making it incomprehensible and potentially requiring many years of rehabilitation. An arguably more reasonable scenario is a partial brain transplant involving only enough tissue to provide key memories and a sense of continuity of identity. A fairly large but indeterminate amount of the brain is devoted to processing and controlling sensory, motor, and autonomic functions such as vision, olfaction, movement, appetite, etc.; if the goal is to move memories and/or identity from one body to another then these portions of the brain are likely both difficult and unnecessary to transplant. In al cases, in the near future, this is not a possibilty, it's an inevitability.
Is it possible to transplant organs from a person’s body who has been declared brain dead? And what organs can possibly be transplanted?
Yes, it is possible for organs to be transplanted from a person who has been declared Brain dead.The types of organs that can be transplanted depends on the patient’s condition after being declared brain dead and also depends on the condition of the organs.Usually the Liver, Kidneys, Eyes and maybe even lungs can be transplanted.
Is a brain transplant possible?
No this is not possible. First, for a person to be an organ donor you have to be brain dead. You must have had some kind of injury or trauma to the head or something like a stroke or aneurysm. So, you brain does not work anymore. You can only donate tissue if you die a cardiac death. So if the brain isn't working then there is no point in transplanting it.
Is it possible to live forever if one gets constant organ transplants?
JR is pretty much on target, but I would add one thing. Once you have a tansplant of any kind, the body spends the rest of its existance trying to rid itself of it, recognizing the new organ to be a foreign body. This is rejection. To combat rejection, you have to take medications daily for the rest of your life to overcome it. This means that the doses need to be exactly right, enough to work and keep working unil the next dose, and little enough to allow the body to still recognize other foreigh bodies like a virus or bacteria. Also, every medicine is a poison administered at a low enough dose to perform the desired function without killing you. Eventually, the poision will do its job, if you live long enough, and the medicine will end up killing you.
