3d human brain atlas for localizing gene expression

Last week the Allen institute released their new atlas with lots of microarray data localized in different regions of human brains. It comes in the form of free software called the "Brain Explorer 2," which takes awhile to download but seems to be worth it. Here is a screenshot of the user interface:

The two brains correspond to their two donors, showing some of the variability in brain structure. The maps were created using structural MRI and diffusion tensor imaging.

Note that you can choose certain regions of the brain to be displayed or not by clicking on that region in the menu to the right. You can rotate the brain relative to any orientation by clicking and dragging the human head in the upper right corner. If nothing else this makes it a useful tool for learning brain anatomy. Check it out.
