Parenting is an essential factor within a child's development, yet the impact of normative variations of parenting on neural emotion processing has not been studied to date. The present study investigated 83 healthy adolescents using functional magnetic resonance imaging and an emotional face-matching paradigm. The faces paradigm elicited an increased amygdala response towards negative facial expressions (fearful and angry each compared to neutral faces) and a significant activation of fusiform gyrus to all emotions separately (fearful, happy, angry faces) compared to neutral faces. Moreover, we investigated associations between neural responses towards emotional faces and mother's parenting behavior (maternal warmth and support, psychological pressure and control behavior). High maternal warmth and support correlated with lower activation to fearful faces in the amygdala. Maternal supportive rather than control behavior seems to have an impact on neural emotion processing, which could also be the key factor for brain functional abnormalities in maltreated children. These results expand existent findings in maltreated children to healthy populations.
