Functional brain network organization during the 40-Hz auditory steady-state response in children with and without autism spectrum disorder
To examine source-level functional brain networks during the 40-Hz auditory steady-state response (ASSR) in children with autism spectrum disorder (ASD) and typically developing (TD) children, emphasizing the significance of this comparison.
Key Findings:
Children with ASD exhibited shorter characteristic path length (PL) compared to TD children (p = 0.0023), suggesting altered network dynamics.
No significant group differences were found for clustering coefficient (CC) or small-worldness (SW), indicating stability in these metrics.
Shorter PL was associated with higher Social Responsiveness Scale (SRS) total T-scores (p = 0.027), highlighting a link between network structure and autistic traits.
Interpretation:
The findings suggest altered large-scale network configuration during externally driven gamma-band synchronization in children with ASD, aligning with existing literature on neural connectivity in ASD.
Limitations:
The sample size may limit the generalizability of the findings, and potential biases in participant selection should be considered.
The study focused on a narrow age range, which may not represent broader developmental trajectories.
Conclusion:
Graph-theoretical analysis of functional brain networks during the 40-Hz ASSR may provide complementary information about ASD-related neural organization, paving the way for future research into therapeutic interventions.
