Frontoparietal and default mode network connectivity varies with age and intelligence
Developmental Cognitive Neuroscience January 27, 2021 M. DeSerisy, Bruce Ramphal, D. Pagliaccio et al.
In children and young adults aged 7 to 25, the connection between brain networks involved in focused attention (frontoparietal network) and internal thought (default mode network) becomes more anticorrelated with age. This shift suggests these networks become more segregated as people mature. Additionally, stronger anticorrelation between specific regions (frontal pole and precentral gyrus) was associated with higher intelligence quotient. The findings indicate that more mature brain network organization relates to better intellectual functioning.
