A study performed at the University of Wisconsin used brain-imaging technology to show that subjects who meditated for eight weeks had increased activity of the brain’s frontal region, which is associated with positive emotions. Subjects also reported less anger, anxiety and other negative emotions. A control group registered no changes in those areas. Those who meditated also showed heightened immune response.
