Towards mapping of the cortex macro-connectivity

Untangling fiber crossing et clustering fiber bundles from q-ball imaging

Towards the inference of the matrix of connectivity of the main cortical gyri using diffusion MRI
green to orange: cortical sulci stemming from T1-weighted images;
blue to red: putative fiber bundles stemming from diffusion-weighted images.

Observing the cortical folds from inside the brain
green fold: central sulcus
colored lines: putative fiber bundles
