Extended Data Fig. 4: Regional heritability.

a. The distribution of the SNP heritability for the 180 bilaterally-averaged regional phenotypes of the 13 neuroimaging modalities. Maximum GWAS sample size = 36,663. Box plots indicate the median value (central line), the interquartile range, and the whiskers indicate the minimum and maximum. b. The cortical spatial topology of SNP heritability for the 13 neuroimaging modalities.
