Mirror, mirror: Viewing your own face, even subconsciously, is rewarding

Researchers have found that the subliminal presentation of images of one’s own face activates a central component of the dopamine reward pathway, thus illuminating the mechanisms behind our powerful ability to automatically prioritize processing of our own face.
