abstract：BACKGROUND:People with anorexia nervosa (AN) have difficulties in a wide range of social-emotional processes. Previous work suggests atypical involvement of the prefrontal cortex (PFC), amygdala, insula, and fusiform gyri during social-emotional processing in AN. METHODS:Twenty women with AN and twenty healthy compari...
