N2 - People seek novelty in everyday life, but they also enjoy viewing the same movies or reading the same novels a second time. What changes and what stays the same when re-experiencing a narrative? In examining this question with functional neuroimaging, we found that brain activity reorganizes in a hybrid, scale-dependent manner when individuals processed the same audiovisual narrative a second time. At the most local level, sensory systems (occipital and temporal cortices) maintained a similar temporal activation profile during the two viewings. Nonetheless, functional connectivity between these same lateral temporal regions and other brain regions was stronger during the second viewing. Furthermore, at the level of whole-brain connectivity, we found a significant rearrangement of network partition structure: lateral temporal and inferior frontal regions clustered together during the first viewing but merged within a fronto-parietal cluster in the second. Our findings show that repetition maintains local activity profiles. However, at the same time, it is associated with multiple network-level connectivity changes on larger scales, with these changes strongly involving regions considered core to language processing.
