Diffusion spectrum imaging

The Brain Unveiled: A new imaging method offers a spectacular view of neural structures. Diffusion spectrum imaging, developed by neuroscientist Van Wedeen at Massachusetts General Hospital, analyzes magnetic resonance imaging (MRI) data in new ways, letting scientists map the nerve fibers that carry information between cells.

Diffusion Tensor Imaging was covered in a spring 2006 Technology Review article, and this link does not require a login. You can see images DTI produces here.

knile, you screwed that up. Do you have the actual link?

Maybe this? Diffusion Tensor Imaging - spring 2006 Technology Review. Not visually interesting though.
Stick with bugmenot or route around.

utterly, utterly elegant. Now if we could just ensure the Neurosurgeon hits the right spot.....

The "route around" goes to an image gallery. The article has a bit more.

DTI isn't new, but there is still ongoing research in visualizing fiber bundles in the brain. If you search google for images relating to diffusion tensor imaging, you get lots of pictures from this kind of research.
The imaging is similar to MRI, except additional scans are used to determine directionality of a imaging element. This directionality can be used to guess at the functional connections of cells in the brain.
