Dan Goleman and Richie Davidson, both titans in their respective fields and best-selling authors, have co-written a new book out now entitled, "Altered Traits: Science Reveals How Meditation Changes Your Mind, Brain and Body." Goleman, a renowned psychologist and science journalist, and Davidson, a prominent neuroscientist and founder of the Center for Healthy Minds, talk about their cutting-edge research in this new book, comparing brain activity of "Olympic level" meditators (such as monks) to meditation beginners and how mindfulness can be restorative for brain health.
