Though every time I see &apos;simple 3D grid&apos; in combination with the brain, I think &apos;scanner or reconstruction artifact&apos;. For my PhD research I&apos;ve worked with DTI (Diffusion Tensor Imaging) data which was very hard to sensibly interpret as &apos;connectivity&apos;: The visualized structures depended very much on the parameters and reconstruction method used. And it was hard to match the visualized structures to actual physical structures.&lt;p&gt;I wonder if they verified in some other way (ie, microscope) that the simple 3D structures were really there. If so, very exciting news!</text></comment>
