Thread: questions on brain & other things

If you respond to this post, make sure your responses to this post are and will be and were as accurate as possible
If you respond to this post, keep in mind etc that cell and/or tissue and/or organ transplant(s) can maybe be done at different times etc ie maybe they dont all have to be done at the same time etc

with our current technology etc

can artificial etc (non biological) cell(s) and/or tissue(s) replace biological cell(s) and/or tissue(s), in the brain of a person who is alive and/or can be alive at some point after getting the cell(s) and/or tissue(s) in their brain replaced with artificial etc (non biological) cell(s) and or tissue(s)


More than thousands of brain cells would eventually have to be replaced, in order to make it so that mutations in the brain would not eventually kill the human/animal that the brain belonged to, right? I mean even if nothing else killed the human/animal that the brain belonged to

Short answer, yes. Long answer, only in a limited sense with today's technology. Experiments have been done wherein people who are paralyzed have computer controls wired into areas of the brain that would otherwise control their paralyzed limbs, and they are able to control a cursor on a screen.

I don't really understand this question. Most adult brain cells do not grow or renew, and if they do it's at a more limited rate than in the rest of the body. It's replication that is the major source of mutations in cells, and if brain cells don't replicate much they're not going to accumulate mutations as quickly as the rest of the body.
