We used seed-based analysis and independent component analysis to investigate functional connectivity among five resting-sate networks including the default mode network (DMN), central executive network (CEN), salience network (SN) sensorimotor network (SMN) and affective network (AN) in children with attention-deficit/hyperactivity disorder (ADHD). Hyperconnectivity was found both within and between these networks. Our findings highlight the “hub” role of the DMN and the CEN among all these functional networks in the mechanism of network dysfunction in ADHD children.
