Resting State Functional Connectivity in Children: A New Paradigm

AbstractResting state functional connectivity (rsFC) can provide a window into the neural architecture of functional networks in the brain. Functional networks measured both during task and during “resting” (task-absent) state are correlated with cognitive function, and much development of these networks occurs between infancy and adulthood. However, rsFC study in young children has been sparse, mainly due to a paucity of child-appropriate neural measures and behavioral paradigms. We present a new paradigm to measure rsFC in children, utilizing functional near-infrared spectroscopy (fNIRS) and Freeplay, a behavioral setup designed to approximate resting state in children. Results suggest this paradigm is practical and has good construct validity and test-retest reliability.
