AdvertisementFalse Signals Cause Misleading Brain ScansJuly 07, 2009Jon HamiltonfacebookEmailThis functional magnetic resonance imaging, or fMRI, of a brain shows activity in the ventral tegmental area (VTA). Scientists gave brain scans to people who said they were in love, while showing them photographs either of their sweeties or other acquaintances, and found that the subjects' VTAs had increased activity when thinking about their loved one. New research says these images may be misleading. (AP/Albert Einstein College of Medicine)
