Several studies have examined seed correlation maps in newborns and infants at different ages, and have indicated that the maps display developmental trajectories. The seed maps of Smyser et al. in premature infants ages <30, 30, 34, and 38 weeks suggest that midline seeds (e.g. anterior cingulate (ACC)) gain bilateral correlations earlier in gestation than lateralized seeds (e.g. face somatomotor or temporal) (Smyser et al., 2010), and Lin et al. report that the strength and extent of somatomotor seed maps increased more rapidly than those of visual seed maps across cohorts of children ages 2 weeks, 1 year, and 2 years old (Lin et al., 2008).
