Story understanding represents a real-world process of information accumulation and integration, where higher levels of story understanding are achieved by integrating the accumulated narrative information into a coherent structure. As subjects watch movies inside a scanner, we investigate how changes in one’s level of understanding are represented as dynamic reconfiguration of whole brain functional networks. Using supervised and unsupervised machine learning techniques, we seek to predict evolving levels of understanding using time-resolved neural signatures. In particular, we investigate how the memory of causally-related previous events are spontaneously reinstated when processing the events of the present moment.
