Passive and motivated perception of emotional faces: qualitative and quantitative changes in the face processing network.

Emotionally expressive faces are processed by a distributed network of interacting sub-cortical and cortical brain regions. The components of this network have been identified and described in large part by the stimulus properties to which they are sensitive, but as face processing research matures...
