Anticorrelated inter-network electrophysiological activity varies dynamically with attentional performance and behavioral states

摘要: Abstract The default mode network (DMN) is thought to exhibit infraslow anticorrelated activity with dorsal attention (DAN) and salience (SN) networks across various behavioral states. To investigate the dynamics of these on a finer timescale, we used human intracranial electroencephalography simultaneous recordings within core nodes three networks. During attentional task performance, sites showed dissociable profiles high-frequency broadband activity. Anticorrelated fluctuations this were found during performance but also intermittently emerged rest sleep in concert expression task-like network-level topographic patterns. Critically, DAN SN activations preceded DMN deactivations by hundreds milliseconds. Moreover, greater lagged, not zero-lag, anticorrelation between was associated better performance. These findings have implications for interpreting antagonistic relationships confirm importance time-lagged inter-network interactions.
