Abstract This study used functional MRI data from the StudyForrest dataset to investigate role of subnetworks default mode network (DMN) during naturalistic stimulus transitions different types and magnitudes. We found distinct activation profiles within DMN: dmPFC subnetwork was specifically associated with character location transitions, MTL preferred temporal while Core DMN responded all three transition types. The multiple-demand instead selectively transitions. These response appeared largely invariant semantic distance implied by All also significantly, in a graded manner, subjective event boundaries. Results suggest specific roles perceiving segmenting events, supporting view that cooperate interpreting continuous external events maintaining an updated contextual model world.
