Humans have meditated for thousands of years, for religious purposes or just to quiet the mind. There are many meditation techniques but for the most part they can be lumped into two broad categories: non directive (mind wanders freely) and concentrative (suppresses random thoughts). Any differences in how the body responds to each type have not been well known prior to this study. A new study led by Svend Davanger from the University of Oslo has investigated what happens in the brain during meditation versus casual resting. The results were published in an open access format in the journal Frontiers in Human Neuroscience.
