I seem to recall from some research I did on neural transplants that
most of the neurons of the brain ("gray matter") are not as resilient
as the neurons of the motor/sense system ("white matter").  There has
been interesting experiments done on replacing damaged neural tissue,
but the only replacement for brain tissue is embryonic brain tissue
(big moral/ethical problem).  There is an out though, the nervous
is immuneologically exempt, and does probably won't reject tissue
grafts, even cross-species tissue grafts.  Experiments along these
lines have been done between cows/dogs/monkeys (I recall).  This
technique is closely related to the transplanting of adrenal gland
cells into the brain to treat/cure the lack of dopamine (?).

Maybe some one else has more of grip on this subject, it's been a while
since I looked at it.  If so, please post (maybe to one of the med groups?)
