In this study, the differences between the activation and functional connectivity conditions of related brain regions by task-fMRI were analyzed to reveal the neural basis of the CIEM and provided more evidence for the hypothesis of mental-model-updating and memory-retrieval-failure. The results showed that the inference scores of retraction condition were significantly higher than that of control condition, and the CIEM exists. In the encoding phase, the activation of left middle temporal gyrus in retraction condition was significantly weaker than that in control condition. While in the retrieval phase, the activation of middle frontal gyrus and anterior cingulate gyrus was weaker in retraction, and the functional connectivity between middle frontal gyrus and precentral gyrus was stronger in retraction. The results suggest that the above brain regions may be involved in the formation of the CIEM, and provide evidence from the neural level that the hypothesis of mental-model-updating and memory-retrieval-failure may explain the different phases of the CIEM formation.
