Personality Profiles Are Associated with Functional Brain Networks Related to Cognition and Emotion

Figure 1. Personality and resting-state correlations and independent components. Top-left: full correlation matrix for the original personality factors. Top-right: normalized representation of the ICA-decomposition for the personality factors into new personality profiles. Each column shows an independent component with the loading onto the original personality factors. Bottom-left: full correlation matrix for the resting-state time series of the 12 regions-of-interest. Bottom-right: normalized representation of the ICA-decomposition for the resting-state time series. Each column shows an independent spatial pattern (or ‘temporal mode’) with loading onto the 12 regions-of-interest. Abbreviations: sgACC – subgenual anterior cingulate, mPFC – medial prefrontal cortex, dACC – dorsal anterior cingulate cortex, PCC – posterior cingulate cortex, PCu – precuneus, OFC – orbitofrontal cortex, dlPFC – dorsolateral prefrontal cortex.

Figure 2. Regions-of-interest. Graphical representation of the regions-of-interest used to extract time series that are the basis the creating the temporal modes. Regions are presented on the left hemisphere. *The right amygdala and hippocampus are not represented but mirror their left equivalent.
