Confidence Intervals for DMN and ‘visual–sensorimotor’ combined components single-factor ANOVA. With the combined components, clear reduction of slow-5 fALFF in the stroke-late (SUBA) population can be observed in comparison to the acute stroke group and healthy old individuals within the DMN. Reductions in the stroke-early (ACU) group were very similar to the healthy older adults (OHA), and did not reach statistical significance. In contrast, behavior of the ‘visual–sensorimotor’ component differed between the healthy aging effect and the effect observed in the stroke-late patient population. In this ‘task-positive’ composite component, the stroke-late population exhibited a trend toward significance in a reduction of slow-5 oscillations (negative in SUBA-Old contrast), while the old presented an increase in those slow-5 oscillations compared to the young (negative in YNG-OLD contrast). **p < 0.001, *p < 0.05, ^#p < 0.1.
