Here's the image: Figure: Group activation regions detected as individuals looked at an image of their beloved compared to an image of an acquaintance. The regions of activation (white) are from anatomically normalized data and are superimposed on a template brain from SPM99. A: The right ventral tegmental area (arrow) was activated. B: The right caudate nucleus (arrow) was activated. Data from other studies of mammals suggest that these regions are involved in reward and motivation functions.
