Higher order diffusion modelling (diffusional kurtosis and multi-tissue CSD) of a whole post mortem human brain with excellent tissue quality was enabled by ultra-high b values from a whole-body 3T scanner with ultra-strong gradients. This was complemented by a novel gradient nonlinearity correction scheme to interpolate signals onto diffusion shells before estimation of fibre distributions. The brain is part of the BigBrain initiative, and will undergo an extensive atlasing procedure. This dataset will thus extend the studies possible on the future BigBrain atlas, allowing investigation into diffusion microstructure imaging and tractography.
