      abstract     = {The default mode network (DMN), the salience network (SN),
                      and the central executive network (CEN) are considered as
                      the core resting-state brain networks (RSN) due to their
                      involvement in a wide range of cognitive tasks. Despite the
                      large body of knowledge related to their regional
                      spontaneous activity (RSA) and functional connectivity (FC)
                      of these networks, less is known about the dynamics of the
                      task-associated modulation on these parameters and the
                      task-induced interaction between these three networks. We
                      have investigated the effects of the visual-oddball paradigm
                      on three fMRI measures (amplitude of low-frequency
                      fluctuations for RSA, regional homogeneity for local FC, and
                      degree centrality for global FC) in these three core RSN. A
                      rest-task-rest paradigm was used and the RSNs were
                      identified using independent component analysis (ICA) on the
                      resting-state data. The observed patterns of change differed
                      noticeably between the networks and were tightly associated
                      with the task-related brain activity and the distinct
                      involvement of the networks in the performance of the single
                      subtasks. Furthermore, the inter-network analysis showed an
                      increased synchronization of CEN with the DMN and the SN
                      immediately after the task, but not between the DMN and SN.
                      Higher pre-task inter-network synchronization between the
                      DMN and the CEN was associated with shorter reaction times
                      and thus better performance. Our results provide some
                      additional insights into the dynamics within and between the
                      triple RSN. Further investigations are required in order to
                      understand better their functional importance and
                      interplay.},
