Cortical regions of significant FSIQ-by-sex interaction (ti = β0 + β1 × age + β2 × age2 + β3 × sex + β4 × age × sex + β5 × FSIQ + β6 × FSIQ × sex, where ti is the set of cortical thickness measurements for all participants). The color bar indicates areas of significant FSIQ-by-sex interaction. On the GRF-corrected maps Brodmann areas with significant FSIQ-by-sex interaction are labeled (p < .0001): BA 24, 29, 30, 31, 44, and 45 on the left and BA 8 and 9 on the right. In nearly all regions of significant FSIQ-by-sex interaction, females show a significant positive correlation of FSIQ with cortical thickness, whereas males show an inverse correlation. An exception is the left anterior cingulate cortex (BA 24) where the correlation is positive in males and negative in females. For females, all correlations are significant (p < .05); for males, correlations are significant in the left posterior cingulate cortex and left inferior frontal cortex. Partial effects of age have been removed. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of the article.)
