Functional connectivity of semantic and default mode networks during narrative comprehension.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Understanding narratives requires at least transient access to the semantic system, to decode incoming content, and prolonged access to the default mode network to maintain and manipulate the narrative model. Subregions within the integrative semantic hubs in bilateral anterior temporal lobe appear differentially sensitive to the need to rapidly decode external input (exogenous processing) versus reflecting on context stored in the narrative model (endogenous processing). The latter is most consistently reported in the middle temporal gyrus portion of the hub, suggesting that this region serves as a critical hinge point, dynamically interacting with the default mode network to facilitate endogenous processing. The present study investigated this by characterizing the functional connectivity profiles of anterior temporal lobe subregions during movie-viewing and examining content-evoked changes in these profiles. Compared to other anterior temporal lobe subregions, middle temporal gyrus was more functionally connected to the default mode network, and these connections were strengthened during moments with limited incoming information, providing viewers with a chance to reflect on the content. Rather than being functionally distinct networks, the semantic and default mode systems dynamically interact to facilitate reflection or endogenous semantic processing. Future work should further characterize how neural systems dynamically shift from integrated to segregated states in response to everyday processing demands.
