Extended Data Fig. 7. Estimation of structural connectivity (SC) matrices for DK80 using standard and special HCP datasets.

a, The ‘standard SC matrix’ was extract from the standard HCP multi-shell dMRI data from 985 HCP participants using state-of-the-art tractography methods (see Methods). b, The ‘special SC matrix’ was estimated using an even better state-of-the-art multi-shell dMRI protocol taking 89 minutes for each of 32 HCP participants at the MGH centre. Please note the increased number of inter-hemispheric connections (upper right and lower left quadrants of the special SC matrix compared to the standard SC matrix). c, The two SC matrices are highly correlated as shown in the scatterplot (r(3160)=0.85, P < 0.001, 95% CI = 0.84–0.86).
