While many studies have focused on how mindfulness meditation affects newcomers to the practice, a new study out of the University of Pittsburgh examined the brains of long-time meditators specifically when they were not meditating. “MRI scans show that after an eight-week course of mindfulness practice, the brain’s ‘fight or flight’ center, the amygdala, appears to shrink. This primal region of the brain, associated with fear and emotion, is involved in the initiation of the body’s response to stress. As the amygdala shrinks, the pre-frontal cortex – associated with higher order brain functions such as awareness, concentration and decision-making – becomes thicker.”
