Network neuroscience is an approach to understanding the structure and function of the human brain through an approach of network science, through the paradigm of Graph Theory. A network is a connection of many brain regions that interact with each other to give rise to a particular function.
Network Neuroscience is a broad field that studies the brain in an integrative way by recording, analyzing, and mapping the brain in various ways. The field studies the brain at multiple scales of analysis to ultimately explain brain systems, behavior, and dysfunction of behavior in psychiatric and neurological diseases.
Network neuroscience provides an important theoretical base for understanding neurobiological systems at multiple scales of analysis.
