Interestingly, we found that intelligence of males and females were underpinned by different neurobiological correlates, which are consistent with their respective superiority in cognitive domains (visuospatial vs. verbal ability).

Additionally, the identified FC patterns are only uniquely predictive to multiple IQ-relevant metrics scores of the same gender but are not predictive to the opposite gender nor to the temperament traits. This study facilitates our understanding of the biological basis of intelligence by demonstrating that intelligence is underpinned by a variety of complex neural mechanisms that engage numerous brain regions, particularly including those identified by P-FIT and basal ganglia, which however show remarkable gender difference.
