Simultaneously and in parallel, is anyone MRI-scanning hundred of generations a year of nematodes and fruit flies to build basic physical correlations in neurology and genetics? Structurally, much simpler and cheaper, biochemically very similar.
[0] Each voxel (='volume element') in a "standard" MRI is cube 0.5-1mm on a side. A C. elegans is about a millimeter long, but only 100 µm wide, so you could fit about a hundred into one voxel. The resulting scan therefore wouldn't tell you much spatially, though I suppose you could do spectroscopy if you wanted to know what a worm was made of.
