  "abstract": "Models of brain dynamics propose that brain activity revisits a repertoire of configurations, and that current input influences which configuration is expressed. How broadly this holds across a person's extended experience is unknown. We analyzed 38-57 hours of fMRI per participant in six adults watching the television series Friends. Participant-specific hidden Markov models identified 42-47 active brain states, and independent fits to separate portions of viewing recovered similar states with similar tendencies to recur. States matched across participants' separately fitted models tended to occur at the same moments of the episodes. Among states retained after temporal screening, features from pretrained video, audio, and language networks partly predicted state identity, most strongly from intermediate-to-late layers. Predictions learned from Friends generalized without retraining to new films, and language-based predictions extended to reading and audiobook listening. State usage corresponded across stimuli little beyond what each recording's spectra and covariance reproduced.",
