Cerebral asymmetry is considered an important marker of the successful development human brain. Recent studies have demonstrated topological asymmetries between structurally hemispheric networks in However, it remains largely unknown whether and how functionally evolve from childhood to adulthood, a critical period that constitutes primary peak brain cognitive development. Here, we adopted resting-state functional near-infrared spectroscopy imaging data construct then applied graph theory analysis quantify characteristics networks. We found adult group exhibited consistent leftward both global local network efficiency, degree efficiency was significantly increased with adulthood. At nodal level, mainly involving frontal, parietal-occipital junction, occipital regions, These developmental patterns suggest protracted maturation segregation left hemisphere could underlie language adulthood provide insight into
