Fig. 7
[18F]-FDG PET correlation matrices of pre-lesion (A, B), QA + VEH (C) and QA + MLK rats (D) and their respective brain network representation (on the right of each matrix), where red edges indicate positive and blue edges negative correlations between nodes (in grey) and the size of each edge is proportional to the size of the correlation coefficient. Correlation matrices are statistically compared between groups and only the connections that are significantly different between the two groups (p < 0.01 with FDR correction) are showed in the upper triangular matrix (E–G). Node degree, betweenness centrality and local efficiency are statistically compared between groups using permutation test (H, I). All brain networks are visualized using BrainNet Viewer [53]
