In a VBM comparison between non-exposed and high exposed groups, we found significant differences in the right middle cingulum (p =0.024) (Table 5b)(Figure 10a). In contrast, comparison of non-exposed and low exposed groups showed differences for the right anterior cingulum (p=0.030) and the left cerebellum (lobes 4 and 5) (p= 0.001) (Table 5c) (Figure 10b). SPSS analyses using the same covariates but also controlling for families with multiple siblings showed similar results for the right anterior cingulum.
