Without going into these experiments in great detail, let me just tell you that when people look at events, persons, or objects that they desire and rate them in exactly the same way in which they rated the visual and the musical excerpts, you find that there is one area, a common area of activity located here in the medial orbital frontal cortex which happens to be the area which is active when you experience beauty, and also happens to be the area which is active when you look at the face of a person you love very much.
