An interesting fact is that the human brain has a fixed number of neuron cells... So the difference between a baby's brain and an adult's is not structural.

I would say that that means that the difference is entirely structural - it's the connections between neurons that change, not the number of neurons. See this article. The number of connections doesn't necessarily increase, but the "right" connections are formed, which means you get smarter.

Also, hasn't very recent research shown that we actually can make some new neurons as adults, at least under some conditions?
