Differences in inter-regional correlations of rCBF of neural substrates in the CPSP and sham groups. A and B. Left and right brain connectivity. The matrix of Fisher’s Z-statistics represents differences in Pearson correlation coefficients (r) between the CPSP and sham groups. Positive Z values indicate a greater r in the CPSP group, and negative Z values indicate a smaller r. C-F. The inter-regional correlation of neural substrates is represented by a graph. The ROIs are represented by nodes, and significant correlations between different ROIs are represented by different line values. The red lines denote significant positive correlations, and blue lines denote significant negative correlations.
