Consciousness is linked to brain regions that synchronize transiently in ways that are both integrated and differentiated. Using dynamic brain networks from fMRI data collected during deep sleep and propofol anesthesia, this study found that unconsciousness reduced the size and flexibility of the largest spatiotemporal module, identified as the dynamic core. These results support the dynamic core hypothesis of consciousness.
