Figure 5. Consistency of PCA across subsets of variables.

A, Independent PCA extraction using only histological variables demonstrated significant replication of PC1 extracted using the full variable set. B, Injury condition affected PC1_HISTO in an equivalent manner to the full-variable extraction (compare to Figure 4E). C, PCA extraction using only behavioral variables significantly replicated the full variable PC for PC1 and PC2, however the sequence of extraction reversed, indicating a reversal in variance explained by PC1_BEHAVIOR and PC2_BEHAVIOR. D, Scores of individual subjects on PC1-3 extracted from just-behavioral variables. The pattern for PC2 _BEHAVIOR recapitulated PC1 from the full variable extraction (compare to Fig. 4E) and PC1_BEHAVIOR recapitulated PC2 from the full-variable extraction (compare to Fig. 4F). *P<.05 for replication statistics, s>0.63.
