Age‐related differences in brain network activation and co‐activation during multiple object tracking

摘要

IntroductionMultiple object tracking (MOT) is a powerful paradigm for measuring sustained attention. Although previous fMRI studies have delineated the brain activation patterns associated with tracking and documented reduced tracking performance in aging, age‐related effects on brain activation during MOT have not been characterized. In particular, it is unclear if the task‐related activation of different brain networks is correlated, and also if this coordination between activations within brain networks shows differential effects of age.
