Speech comprehension involves the dynamic interplay of multiple cognitive processes, from basic sound perception, to linguistic encoding, and finally to complex semantic-conceptual interpretations. How the brain handles the diverse streams of information processing remains poorly understood. Applying Hidden Markov Modeling to fMRI data obtained during spoken narrative comprehension, we reveal that the whole brain networks predominantly oscillate within a tripartite latent state space. These states are respectively characterized by high activities in the sensory-motor (State #1), bilateral temporal (State #2), and DMN (State #3) regions, with State #2 acting as a transitional hub. The three states are selectively modulated by the acoustic, word-level semantic and clause-level semantic properties of the narrative. Moreover, the alignment with the best performer in brain state expression can predict participants’ narrative comprehension scores. These results are reproducible with different brain network atlas and generalizable to two independent datasets consisting of young and older adults. Our study suggests that the brain underlies narrative comprehension by switching through a tripartite state space, with each state probably dedicated to a specific component of language faculty, and effective narrative comprehension relies on engaging those states in a timely manner.

“…In this study, we used the individual approach to make sure the neural event structures were authentic representations of each fMRI participant's true event segmentations. Hyperalignment may help reduce individual differences across brains (Haxby et al, 2014;Guntupalli et al, 2016;Tan et al, 2022), enabling us to return to the group analysis of neural activities and better investigate the generalizability of the neural event segmentation of auditory stimuli.…”

Event segmentation theory explains how we parse the continuous stream of information into meaningful event models. Narratives are useful stimuli for studying this phenomenon, as the flow of information and the way we make meaning of them mirrors how we comprehend and make sense of our daily lives. Many studies have focused on the segmentation of audiovisual stimuli such as movies. In this study, we investigated how the brain parses narrative information when the input was only auditory, using two story recordings. Behaviorally annotated boundaries of the story text were analyzed and used as the behavioral benchmark for the neural-behavioral comparison of event structures. Our results showed that the angular gyrus and posterior cingulate cortex activity produced neural event structures that significantly matched with the behavioral event structures, while the early auditory and early visual cortices’ neural-behavioral matches were not consistently significant for both stories. This pattern demonstrated that successful matching in the default-mode network regions was related to neural processes involved with parsing the continuous narratives, rather than changes in sensory-related features. Our study also found nuanced differences between AG and PCC’s neural response to audio-only narratives, which suggests a potentially more prominent role for the angular gyrus in processing narratives that are presented solely auditorily than might be expected from data on visuo-auditory stories.
