Re: Could you transplant a human brain in a chimpanzee?

Sorry to disappoint you, but with even the newest of technologies we 
have right now, it wouldn't be possible to transplant brains even from one 
human to another, never mind the additional complications of transplants 
across species. 
The brain and spinal cord (together called the central nervous system - 
CNS) are actually one continuous organ with lots of blood vessels going in 
and out. This would make the mere surgery incredibly difficult. Also, the 
central nervous system does not work in isolation, you'd need to be able 
to connect all the inputs and outputs to and from the brain correctly. 
Since neurons in the nervous system typically do not divide or grow back 
if they are damaged, forming new connections would be difficult. There are 
some scientists working hard to trick these cells into growing back to 
help people who are paralyzed, but they're not there yet. Finally the 
balance of chemistry within chimps would probably be slightly different 
from that in a human, and this would affect how the brain functions.
All that being said and done, *IF* we were somehow able to get a brain 
transplanted into a chimp, I am not sure what that human/chimp would feel 
and how they would see the world. My _guess_ would be that  the chimp 
would probably act somewhere between a normal chimp and a normal human.
