Dynamic fMRI Functional Connectivity
Analyzing dynamic resting-state fMRI connectivity networks in SuperAgers using novel statistical metrics.
Understanding how different regions of the brain communicate over time—known as dynamic functional connectivity—is crucial to unraveling the mysteries of cognitive aging.
Focus
This research analyzes resting-state fMRI data from “SuperAgers” (older adults whose memory abilities rival those of young adults). We mapped complex brain networks to identify resilient connectivity patterns that may protect against age-related cognitive decline.
Techniques
We utilized sliding-window correlation techniques alongside graph theory to quantify network integration and segregation, providing new insights into the neural mechanisms of exceptional cognitive preservation.
