These results suggest that the APOE4 gene does not directly affect these parts of the brain, and changes may only be seen if adults start to develop Alzheimer’s disease.

Importantly, we showed that there were no differences between adults with/without the APOE4 gene. We focused on univariate and connectivity differences during event boundaries; But also examined full-movie/ whole brain functional connectivity and graph-theoretical measures like system-segregation.

Our lab and others have shown that the brain regions that are active when we watch movies overall with regions that are damaged by Alzheimer’s disease. In this study we used MRI brain imaging data collected from 425 people while they watched a short Alfred Hitchcock movie.

Apolipoprotein E e4 (APOE4) is a significant genetic risk factor for Alzheimer’s disease. However, it is not known whether there are differences in the brains of healthy adults who carrying the APOE4 gene.
