Fig. 6.
Comparison of the tensor fractional anisotropy (FA) between (a) mean control and (b) mean shiverer brains. The (shiverer-control) difference images (c) show a reduction in FA in the external capsule, internal capsule, anterior commisure and cerebellar white matter. FA appears to be much less sensitive than Tr(D) to dysmyelination effects. The difference colorscale is dimensionless.
