Abstract
Harm avoidance is a biologically informed conceptualization of trait anxiety. It reflects the heritable tendency to react strongly to punishment or frustration by inhibiting ongoing behavior. Harm avoidance has been discussed in particular as a risk factor for major depression and anxiety disorders. In order to derive biomarkers for these disorders, it is imperative to understand the neural implementation of harm avoidance in the normal range. In this chapter, we review the personality neuroimaging literature through a harm avoidance lens: a total of 41 empirical studies using different imaging techniques in different modalities are reviewed. Studies point toward a network comprising a frontal, a temporal, and a cingulo-insular complex. Results provide an ample ground for future research that is needed to derive a full functional model of the neural implementation of harm avoidance.
