But are neurons created, or merely linked by learning new things? If the former, is your 31mil number taking this into account?

Your brain never makes new nerves. See problem with spinal cord injuries.

First line
"The genesis of new cells, including neurons, in the adult human brain has not yet been demonstrated."
and in the discussion.
"Although our results demonstrate that cells in the adult brain undergo cell division and that some of the newly generated cells can survive and differentiate into cells with morphological and phenotypic characteristics of neurons, we have not proven that these newly generated cells are functional."

Aargh!
The paper is from 1998 - there`s been a lot more research done in the past 7 years.
Fresh spinal cord injury in rats can be reversed almost completely by administering a drug cocktail. It`ll take another 10 years for it to work in humans.
