Top views of average GM RAVENS Maps in different age groups for the advanced, delayed, and normal subjects. The color map represents lower RAVENS values (i.e., less GM) in blue and higher RAVENS values (i.e., more GM) in red. A consistent developmental pattern is observed for all groups similar to that shown in Figure 1. However a shift can be observed between the 3 groups, where the GM decrease happens earlier in the advanced group, and later in the delayed group, compared with normal group. The * has been used to show the correspondences, as an indicator of this developmental shift.
