Meditation Produces Enduring Changes

8 weeks of MBSR and compassion meditation were shown to affect amygdala response outside of formal meditation, as reported in Science Daily.  In the paper "Effects of mindful-attention and compassion meditation training on amygdala response to emotional stimuli in an ordinary, non-meditative state" researchers report "this is the first time that meditation training has been shown to affect emotional processing in the brain outside of a meditative state."

Kind of surprised this hasn't been shown before.
