P 106 Functional magnetic resonance imaging of appetitive aggression in martial artists

The direct execution as well as the visual perception of violence can have a hedonistic aspect and elicit positive arousal. (Elbert et al., 2010) So far, neurobiological correlates of this "appetitive" form of aggression have not been investigated in healthy subjects.Using functional magnetic resonance imaging (fMRI), we tested if subjects who act violently (martial artists) showed greater brain responses to violent images compared to controls in the subcortical reward-associated areas of the mesolimbic dopaminergic system.
