Correlations of white matter microstructure with physical activity and cognitive performance. The correlation between white matter microstructure and (A) physical activity and (B) cognitive performance. All data points were labeled in black dots, with a gray fitting line and a gray patch represent the 95% confidence interval. White matter tracts significantly correlated with physical activity and cognition and were labeled with green and red. All the correlations were significant with FDR-corrected p < 0.05. Noted that 15 participants who completed 72-h recording had actigraphy information; other assessments included all 31 participants.
