BOLD activity differences are quantified by the bootstrap ratio (BSR) statistic. The red scale represents transitions > meta-stability, whereas the blue scale represents meta-stability > transitions. a During movie-viewing fMRI, greater BOLD activity was observed during transitions than meta-stable timepoints, in several midline regions, including anterior cingulate cortex, posterior cingulate cortex, and visual association cortex. b During resting-state fMRI, greater BOLD activity was observed during transitions than meta-stable timepoints in similar midline regions. c Substantiating the subjective similarity of a and b, conjunction analysis revealed substantial voxel-wise overlap for regions activated during transitions (see Supplementary Tables 1–3 for voxel cluster details).
