Small nitpick:_ the glial cells are mixed up with the neurons of the
brain, if you transplant it, you will get the glial cells too.

I have already answered this in a private mail, but I just realized
yet another way to get around the fact that neurons doesn't divide
well; I have a paper called "Neuronal progenitors as tools for cell
replacement in the nervous system", which explains how progenitor
cells, genetically modified fibroblasts and transplants can be used to
replenish the brain. Quite interesting stuff, but still in its
