Could meditating for 30 minutes a day actually change your brain structure? Sara Lazar, PhD, a neuroscientist at Mass General, has compiled brain imaging data suggesting that it can. In a controlled study of two groups of people who had never meditated before, Dr. Lazar found significant growth in brain volume in the group that participated in an eight-week #meditation program relative to the control group. The main areas of growth included regions having to do with learning, cognition, empathy and compassion. The amygdala, the part of the brain related to anxiety, fear and stress, also got smaller in the group that meditated.
