A similar study, using a subsample of the earlier study, found not only significant reductions in the area of posterior CC (splenium), but also marked inferior and anterior displacement in the FASD group compared to controls. Among the non-dysmorphic FASD subjects, this displacement of the splenium was less than that for the FAS group and the amount of CC displacement correlated well with impairment in verbal learning ability, suggesting that CC displacement is a better predictor of verbal learning than the regional CC area144.
