Simulation of the brain

Wow, that would be great. A brain creating another to study about itself.

Now, I have a doubt. Wouldn't all this lead to recursion? One brain creating another to study about brains. If the created brain is a perfect simulation, even that would create another brain to study about brains. And this process goes on and on and on ....till what/when?

The following is an excerpt from here

An effort to create the first computer simulation of the entire human brain, right down to the molecular level, was launched.

The “Blue Brain” project, a collaboration between IBM and a Swiss university team, will involve building a custom-made supercomputer based on IBM’s Blue Gene design.

The hope is that the virtual brain will help shed light on some aspects of human cognition, such as perception, memory and perhaps even consciousness.
