Some Cool Science

A man recovered from a coma after his brain rewired itself. From the description in the article, it sounds like they tracked the neuronal connections with DTI--Diffusion Tensor Imaging. It's one of the hot research areas in MR right now; it acquires multiple images and causes them to have contrast that depends on the rate of diffusion in a specific direction. By doing some trickery, it can tell that direction of diffusion in the image.

Yeah, that's a good thing. I think more effort should be put into this sort of thing, but in the next 50 years I don't see science making dramatic breakthrus to rebuild brain tissue; perhaps spinal cord, but not brain, it's too complex and intertwined. That said, if any therapy is going to take place, we need to figure out how to make neural stem cells from adult patients; that's the holy grail.
