The role of the amygdala for the processing of valence and arousal is a matter of debate. Using event-related functional magnetic resonance imaging, we tested valence-specific amygdala effects during; attentional distraction. Subjects attended to a matching task in the foreground of neutral pictures, and of negative and positive pictures matched for arousal. Negative pictures elicited stronger amygdala activation than neutral or positive pictures, suggesting valence-specific amygdala responses under attentional load. (C) 2008 Elsevier B.V.
