Figure 3. Correlation matrices and exploratory factor loadings for ROI intercepts and slopes, estimated using left-right average values for ROIs.

Figure 3

Note. Exploratory factor analyses. (a) density plots of the correlation magnitudes among freely-estimated intercepts and slopes; (b) heatmaps of the correlations among freely-estimated latent intercepts (left) and slopes (right), intercept axes are fixed according to the hierarchically-clustered slope matrix; (c) loadings of each ROI’s intercept and slope on a general factor of cortical change (“g”) and on two additional factors identified from an exploratory Schmid-Leiman factor analysis, conducted on the same latent correlation matrices as shown in (b). Loadings reported in Supplementary Table 9. Factor F1 pertains to fronto-temporal, and F2 to occipito-parietal regions.
