Maps of the mean posterior volume fractions for the second (yellow-red) and third (blue) fibre compartments. All maps are thresholded at 0.05. The mono-exponential model fits a second fibre everywhere except in the ventricles and parts of the corpus callosum. A third fibre is fitted at the interface between CSF and brain tissue. The aternative Gamma distribution model only supports crossing fibres in white matter areas.
