During the execution of complex continuous cognitive tasks, the brain elaborates information over multiple domains and time scales, integrating it across space and over time. In literature, only few rs-fMRI works report how resting state networks (RSNs) change over space and time when stimulated by external inputs. We investigated the dynamic changes in brain activity occurring in subjects listening to a narrated story. Results show that RSNs respond to the stimulus with specific dynamics of alteration and suggest the existence of a spatiotemporal hierarchy of changes, the levels of which depend on the specific activity each network is involved in.
