Dynamic network interactions supporting internally-oriented cognition

Darya L Zabelina and Jessica R Andrews-Hanna

Recent advances in systems neuroscience have solidified the view that many cognitive processes are supported by dynamic interactions within and between large-scale brain networks. Here we synthesize this research, highlighting dynamic network interactions supporting a less explored aspect of cognition with important clinical relevance: internally-oriented cognition. We first present a brief overview of established resting-state networks, focusing on those supporting internally-oriented cognition, as well as those involved in dynamic control. We then discuss recent empirical work emphasizing that many cognitive tasks involving internally- oriented processes — such as mind-wandering, prospection, and creative thinking — rely on dynamic interactions within and between large-scale networks. Our aim is to provide a snapshot of emerging trends and future directions in an important aspect of human cognition.
