There are other useful methods for mapping the brain. MRI and PET scans can be used. (http://www.nytimes.com/2010/08/10/health/research/10spinal.html) www.nytimes.com
Also, genechip analysis and the tried-and-true protein blot offer up a lot information. Check out the Allen Brain Atlas... (http://www.brain-map.org/)
The mouse brain is very useful as a sort of analogy for the human brain, given the homology of genes and proteins. Of course, mice lack some of the functionality that we do, but a mouse brain can be "stopped" in vivo (using difficult techniques) or a fetal mouse brain can be dissected and its tissue actually grown live in vitro. These techniques offer even more opportunities for figuring out the nuances of different parts of the brain.
And - no surprise - we still have a lot to learn about it.
