Figure 4.

The sign of fc-walking relationships is generally consistent within enriched network blocks. Locations and signs of brain–behavior relationships are illustrated for ROI pairs contributing to enrichment. Spheres represent ROIs. Red and blue sticks represent positive or negative brain–behavior relationships, respectively, between functional connectivity (fc) for an ROI pair and walking scores. (a) At 12 months, all enriched network blocks show primarily positive or negative fc-walking relationships. (b) Similar uniformity occurs at 24 months, with the exception of DAN–CO. Hatched boxes enclose significant versus discovery results.
