It's possible to transplant a brain in the future?

Question

can we cultivate brain cell

Answer 1

And, just as scientists started to make discoveries regarding spinal cord regeneration, another surgeon, a Dr. Tom Burke wrote this:

"I wonder, with an almost tenuous whisper, will we ever transplant the brain? The brain sits in our skull casing and its plug-ins are actually quite few: 12 pairs of large nerves, a few large vessels for blood supply and the spinal cord. Stop and consider for a moment how brain spinal cord repairs or perhaps even brain transplants would transform humanity.
...
A brain transplant has an intriguing sound. How near to immortality does this take us? But, at what cost? Imagine i f the person most close to you had advanced cancer but his or her brain was still OK? And then, suddenly, a body became available for transplant: A body whose brain had died. What if the body was much younger or older? What if the gender was different? Who would this new person be? Marriage, family and ownership?"



Here's a way by which they will be able to re-attach severed cranial nerves:

Nanofiber Scaffold Supports Optic Nerve Regrowth

Using nanosized peptides, a team of researchers has built knitted scaffolds that may be used to regrow damaged optic nerves. The team from the Massachusetts Institute of Technology (MIT; Cambridge, MA), has managed to restore limited sight to blinded hamsters using nanoparticles resembling small fibers.

To conduct the experiment, the researchers cut the neural pathway that enables vision in hamsters. They then injected 16 of 47 adult hamsters with a solution containing nanofibers. The material was injected into the gap within an hour of the pathway being cut. After the first 24 hours, the researchers noted that the gap was reduced and that axons seemed to have grown through the center of the cut.

When tested, three-quarters of those hamsters could function well enough to identify a food source. None of the 31 hamsters that did not receive the nanosolution regained sight.

According to the lead researcher, Rutledge Ellis-Behnke, the technique offers a possible method for repairing neural connections. When neural pathways in the brain or spinal cord are damaged, they don’t usually heal. The damage can result in lifelong brain damage and paralysis.

When a neuron is cut, he says, it sprouts a growth tip, much like a tree whose branch has been cut. After that initial step, however, the growth stalls and scientists are not sure why. Axons can be encouraged to extend by exposing them to growth factors. But they rarely extend far enough to bridge the large gaps typical of most optic nerve injuries, he says.

Ellis-Behnke believes that the nanoparticles may block signals that trigger an immune response. Alternatively, he speculates that perhaps the nanoparticles coat the growing tip of the neuron, blocking any signals that tell the axons not to grow.

Gerald Schneider, one of the team members, estimates that 30,000 axons reconnected in the hamsters, compared with only around 30 in previous experiments using other approaches, such as nerve growth factors. The nanoscaffold is similar in size and shape to sugars and proteins. The team believes that the similarity between the size of the fibers and the features on neural material is what encourages the axons to bridge the gap. The scaffold is biodegradable and appears to eventually break down harmlessly.

And while the results are promising, Schneider explains that the technology is not necessarily a cure-all. “It will not replace neurons that have been destroyed. The axons are slow to grow. We have used the method only for situations in which they have to grow very short distances to get some recovery of functions.”

Answer 2

I think if humanity continued forever, we would eventually learn how to do seemingly impossible things like brain transplants. I think if there was a successful brain transplant they would switch bodies, but the people would probably be uncomfortable for a while because of different weight, agility, etc

Answer 3

U never know! maybe in our near future we may be able 2 transplant a brain. I think we'll be able to do that only if v r optimistic. so lets hope 4 d best.

Answer 4

u can never know ...may be ..if u said 50 years ago that it would be possible to transplant a liver or a kidney no one would have ever believed it

Answer 5

That would be cool if they could come premade with skills or memories already in there, so if you want to get really good at martial arts, do like what Neo did and just load it in.

Answer 6

Maybe. After all, all great inventions and discoveries start with someone dreaming about them and asking questions; and you asked the question! :))
