Abstract
Broad personality traits that underlie individual differences in response to stress and vulnerability to anxiety and depression in humans have been known for some time to have a genetic basis. These traits have been described variously in humans as neuroticism, trait anxiety, and harm avoidance. Animal models of emotionality offer the opportunity to investigate the genetic basis of these traits with a greater degree of experimental control than in human studies and thereby to better understand the genetic etiology of emotionality. Recently, evidence for an overlap between the genetic basis for emotionality in rodent models and trait neuroticism in humans has emerged, which may help determine whether there is a common set of genes that contribute to trait neuroticism in humans and analog models of emotionality in animals. © 2007
