Brain network dynamics in transitions of consciousness reorganize according to task engagement

Samika S. Kumar, Anat Arzi, Corinne A. Bareham, Javier González-Castillo, Isabel S. Fernandez, Enzo Tagliazucchi, Pedro A. M. Mediano, Peter A. Bandettini, Tristan Andres Bekinschtein

The paper shows that during decreased alertness, active task engagement increases frontoparietal and long-range brain synchronization, while passive listening increases thalamocortical synchronization.
