Abstract
En 中文
• DMN functional connectivity decreases with greater problematic use of the Internet. • DMN hub connectivity predicts whole-brain network topology. • DMN connectivity mediates the relationship between PUI and network topology.
Keywords:
Problematic use of the Internet (PUI)
Default mode network
Graph theory
Brain network topological properties
