Brain waves show patterns for deciding which faces we prefer

Faces play a very important role in our social life. We make complex social decisions based on facial appearance. But we know little how we make a preference decision when the two faces are closely matched (e.g., age, race, gender, gaze, facial attributes, facial emotion). Is there any specific brain activity pattern associated with our preference (or non-preference)? Can these patterns be identified before our conscious decision?
