You still will need a powerfull MRI setup but no longer will the problem be in the wetware. I do have concerns about the effects of these proteins on the brain. Also, when you hit the brain with all this magnatism arn't you going to be skewing the images by dragging the calcium towards the magnets? What effect will this have on brain tissue? I guess thats why they're moving toward animal studies.

Scientists at MIT have engineered a nano-sized calcium sensor that may eventually shed light on the intricate cell-to-cell communications that make up human thought. Alan Jasanoff and his team at the Francis Bitter Magnet Lab and McGovern Institute of Brain Research have found that tracking calcium, a key messenger in the brain, may be a more precise way of measuring neural activity, compared with current imaging techniques, such as traditional functional magnetic resonance imaging (fMRI).
