An animation of a brain model created from diffusion tensor imaging data.

You can download and use this software for free.  It gives you a 3D model of the brain that is awe inspiring!

The program Trackvis 0.5.1 is available here http://www.trackvis.org/download/

There is a form to fill out, but don’t worry, you don’t need to be a scientist to use it.  Fill out only the required fields, and make stuff up if you need to.

The files you open with trackvis are DSI and DTI splines, avalible here.

“The goal of diffusion tensor imaging is to image the diffusion of water in the brain. DTI uses the fact that water has a lot of these hydrogens, which align to the magnetic field that is applied. So what we do is magnetize a slice of the brain, wait, and then read out that slice of the brain again and again and again, using varying gradient fields of magnetization.

What happens is that water molecules that moved during this magnetization will have a different magnetization than their neighboring water molecules which leads to a change in image contrast. When you do this in more than two directions you will be actually be able to also calculate the direction of water diffusion. “
