The brain-activity differences of the incongruent condition in the numerical Stroop task across the two phases of exercise intervention. (a-d) the spatial pattern of brain activities of both Young and Old groups. Multiple comparison correction of these activation maps adoptes the ClusterSim corrected to p < 0.05. (e–g) the changes of fMRI signals across the three times points, where the regions were prescribed from AAL3, encompassing frontoparietal, default mode network (DMN), and sensorimotor and visual areas. Green and orange lines indicate Old and Young groups, respectively. The "*" indicates the significance level 0.01 < p < 0.05, and "**" means the p < 0.01 with the Bonferroni test.
