Neural interactions in occipitotemporal cortex during basic human movement perception by dynamic causal modeling.
Article in Brain imaging and behavior, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Action recognition is an essential component of our daily life. The occipitotemporal cortex (OTC) is an important area in human movement perception. The previous studies have revealed that three vital regions including the extrastriate body area (EBA), human middle temporal complex (hMT+), and posterior superior temporal sulcus (pSTS) in OTC play an important role in motion perception. The aim of the current study is to explore the neural interactions between these three regions during basic human movement perception. Functional magnetic resonance imaging data were acquired when participants viewed dynamic videos depicting basic human movements. By the dynamic causal modeling analysis, a model space consisting of 576 models was constructed and evaluated to select the optimal model given the data. The information of the visual movement was found to enter the system through hMT+. We speculated that hMT+ would be the region to show sensitivity to the presence of motion and it subsequently influence and be influenced by the other two regions. Our results also revealed the manner in which the three regions interact during action recognition. Furthermore, We found significantly enhanced modulated connectivity from hMT+ to both EBA and pSTS, as well as from EBA to both hMT+ and pSTS. We inferred that there may be multiple routes for human action perception. One responsible route for processing motion signals is through hMT+ to pSTS, and the other projects information to pSTS may be via the form-processing route. In addition, pSTS may integrate and mediate visual signals and possibly convey them to distributed areas to maintain high-order cognitive tasks.
