Frontoparietal functional dedifferentiation during naturalistic movie watching among older adults at risk of emotional vulnerability

2 months 3 weeks ago
Functional dedifferentiation, a hallmark of brain aging particularly evident within the frontoparietal network (FPN), has been extensively investigated in the context of cognitive decline, yet its implications for late-life mental health remain poorly understood. Leveraging naturalistic paradigm combined with gradient mapping techniques, the present study investigated FPN functional dedifferentiation-quantified by functional dispersion of FPN in the multidimensional gradient space-during...
