FIGURE 4.

Brain regions showing RMFG-related FC alterations in the PD-FOG group compared with the PD-nFOG group (p < 0.001, AlphaSim-corrected). Red represents increased rsFC in the right precuneus and cerebellum, and blue represents decreased rsFC in the right inferior and superior frontal gyrus. The t-value scale is seen on the lower left of the image (A). Correlations between FC and FOGQ scores. FOGQ scores were negatively correlated with impaired connectivity between the RMFG and right cerebellum in the PD-FOG group (B).
