In a study investigating age-related differences in multiple object tracking, we have demonstrated decreased task-related activations in the dorsal attention network (DAN) and decreased task-related deactivations in the default mode network (DMN) for older adults. Correlation between brain network components revealed stronger correlations in task-related activations within DMN components for younger adults and stronger correlations between task-positive and DMN components for older adults, indicating age-related alterations in the coordinated network-level activation during attentional processing.
