Sorry to disappoint you, but brain cells, meaning the nerve cells, usually don't proliferate (there are about 10 times as many supporting cells (glia cells) in the brain, but unlike the nerve cells, they don''t process information)
However, nerve cell projections can regrow if damaged. The result depends on whether the sheaths in which they run are intact or not. If they too are damaged the nerve endings may loose track and go places they're not supposed to. Problem is: Your brain don't know this happened. One example: Damage to your facial nerve, which among other functions controls secretion of saliva and tears, may result in "crying" whenever you see or smell a well prepared steak. Or other things you'd like to eat.
