Abstract

It is unknown whether gastric dysrhythmias contribute to disgust avoidance. By normalizing gastric state with domperidone and measuring oculomotor avoidance of disgusting images, Nord et al. discover that domperidone reduces oculomotor disgust avoidance following an exposure task. This suggests that gastric rhythm is one cause of disgust avoidance.
