Functional signature of the entire characteristic anger connectome

Explanation

Research on the brain correlates of anger has been limited by the unreliability of testing and retesting of functional brain measures.

To address these limitations, we conducted a data-driven analysis of variability in functional connectivity across the connectome in a sample of 1,048 young adult volunteers, and multidimensional matrix regression analysis showed that self-reported trait anger mapped to variability in whole-brain functional connectivity patterns in three brain regions that serve behavior-related functions.

The findings provide new neuroimaging evidence for interpreting trait anger as a greater propensity to elicited behavior.
