Overall, results pertinent to the DMN from several studies indicate that 1) in two studies, Fransson et al. (Fransson et al., 2009; Fransson et al., 2007) found no DMN-like component in infants, and no significant correlations between frontal and parietal components, though the parietal component contained midline and lateral parietal cortex, similar to the posterior portion of the DMN, 2) Smyser et al. (Smyser et al., 2010) found only insignificant MPFC-PCC correlations in their preterm infants, but significant MPFC-PCC correlations were found in some term infants, 3) Gao et al. (Gao et al., 2009) reported components in neonates that were distributed and which somewhat resembled portions of the DMN, 4) Kelly et al. (Kelly et al., 2009) found no anterior-posterior correlations from ventral ACC seeds in children 9–13, and noted substantial increases in long-distance correlations from these seeds throughout adolescence, 5) Fair et al. (Fair et al., 2008) detected sparse but significant correlations from an MPFC seed to PCC in 7–9 year olds, but most DMN ROIs in children lacked strong correlations with one another, and changes in correlation strengths
