Abstract:

Research on functional connectivity has contributed to a large body of literature on the relationships between functional brain networks and human behavior, emotions, and cognition, as well as providing new insights into the underlying mechanisms of disorders. How those networks mature and develop during childhood and adolescence is pertinent to pediatric neuropsychologists, in terms of case conceptualization, and assessment (e.g., understanding how differences in functional connectivity impact testing at different stages of development) and recommendations. The article by Minnigulova et al. (2025) provides an example of how recent investigations seek to inform diagnostics and case conceptualization of neurodevelopment using the analysis of functional connectivity, while also providing an example of differing developmental courses in functional connectivity maturation. This presentation will provide a brief review of current understandings of the developmental course of the maturation of the default mode network

Objectives:

1) Describe differences in between-network and within-network connectivity when comparing children with typical development and children with autism spectrum disorder.

2) Compare the typical developmental trajectory of the default mode network in children with typical development with children with autism spectrum disorder.

3) Discuss implications of the developmental trajectory of the default mode network on broader neurodevelopment and behavior.
