In this study, we present the Chenonceau dataset : a novel 11.7T MRI dataset of the entire human brain, combining an ultra-high resolution anatomical scan at 100μm with diffusion scans at 200μm using strong diffusion sensitizations.

Figure 4: Whole brain connectogram computed from the analytical Q-ball model using a regularized deterministic fiber tracking method; (a) 3d view of the whole connectogram; (b) zoom in frontal lobe superimposed onto the 200μm GFA map, revealing dense and finely structured tracts entering the cortical ribbon; (c) zoom in the right hippocampus superimposed onto the 200μm GFA map, revealing its complex inner fiber organization.
