The neural substrate of high intelligence performances remains not well understood. We propose to investigate the structural brain connectivity measurements and their relationship with the intelligence performances, as measured by the WISC-IV scores of 57 children. We found strong correlations between children brain network density and intelligence scores. Moreover, several correlations were found between integration and redundancy graph metrics suggesting that intelligence performances are probably related to homogeneous network organization.
