These data provide the first structural evidence for experience-dependent cortical plasticity. Finally, the thickness of two regions correlated with meditation experience. Between-group differences in prefrontal cortical thickness were most pronounced in older participants, suggesting that meditation might offset age-related cortical thinning. She has shown that in long term meditators brain regions associated with attention, interception and sensory processing were thicker in meditation participants than matched controls, including the prefrontal cortex and right anterior insula. Since then she has done work with the wives of soldiers who have had one rotation in combat and are up for redeployment and has found that this group also benefit from learning mindfulness techniques: This is a TED talk by Sarah Lazar who is a neuroscientist and a meditator: This is link to her meditation research website: She has shown that the amygdala, which is the part of the brain that senses danger, shrinks in people who meditate. This was only true for the soldiers who were in the “high meditator” group. These are the major research findings since 1982 from the University Massachusetts Center for Mindfulness: Amishi Jha has done research with soldiers before they were deployed and found they made fewer errors in combat due to less mind wandering.
