Across human populations, individual ability to deal with stress and anxiety spans a wide range. The causes of emotional resilience are complex; this paper shows the contribution of genetic variance in expression of neuropeptide Y (NPY), an anxiolytic peptide released in emotion-related neural circuitry. Genetic variants were predictive of not only NPY levels, but also fMRI and PET activation in response to emotional stimuli and pain-induced stress.
