Before revision:  Using double generalized linear model, the mean model results is almost the same as generalized linear model, we found crystallized intelligenceare more associated with cortical thickness than fluid intelligence in adolescents around 10 years old. We found the frontal gyri regions thickness are negative with intelligence , which is consistent with previous study. Intelligence appears to be associated with widespread increased mean differences and decreased heterogeneity in  cortical thickness .
After revision:  Using double generalized linear model, the mean model part, the thickness of the frontal lobe like superior frontal gyrus was negatively related to intelligence, while the surface area was most positively associated with intelligence in cortical thickness .
