Earlier studies on adults have shown that functional connectivity (FC) of brain networks can vary depending the state and cognitive challenge. Network has been investigated quite extensively in children resting state, much less during tasks is largely unexplored between these states. Here we used magnetic resonance imaging independent component analysis to investigate architecture large-scale 16 (aged 7–11 years, 11 males) young 22–29 10 visual working memory tasks. We identified major neurocognitive intrinsic (ICNs) both groups. Children had stronger FC than within cingulo-opercular network task performance, after controlling for performance differences. During tasks, also default mode (DMN) right frontoparietal (rFPN) networks, anterior DMN frontopolar network, whereas coupling rFPN. Furthermore, compared modulated strength regarding rFPN differently The correlated with age so younger they were, was FC, this slower performed group differences reported here, observed correlations provide insight into normative development preadolescent link maturation improving performance.
