Jealousy research. Magnetic resonance imaging (MRI) brain scans carried out as part of research into human jealousy. The research is being carried out by neuropsychologist Kenneth Levy at the University of Pennsylvania, USA. The studies look at difference between male and female jealousy. The images at top are sagittal (from the side) functional MRI scans (fMRI) of a man (left) and woman (right). The bottom images are the corresponding axial brain scans. Levy's research has shown that in the brain the amygdala (controlling fear and aggression) and the hypothalamus (sexuality) are activated differently in men and women.
