Study Shows Meditation Can Change Your Brain

January 26, 2011

Do humans hold the power to change their own gray matter? The answer is yes, according to this week’s meditation news: meditation can lead to structural changes in the brain.

Follow this link for a quick one-minute audio report on the study from Scientific American, or read on for the news from U.S. News & World Report:

…[Researchers] used MRI to assess the brain structure of 16 volunteers two weeks before and after they took the eight-week Mindfulness-Based Stress Reduction program at the University of Massachusetts Center for Mindfulness. The program included weekly meetings to practice mindfulness meditation and audio recordings for guided meditation practice. The participants were asked to keep track of how much time they practiced each day.

The researchers also analyzed MRI scans of a control group of people who did not meditate for comparison.

The meditation group participants spent an average of 27 minutes a day doing mindfulness meditation exercises. The MRI scans taken after the eight-week program revealed increased gray matter density in the hippocampus (important for learning and memory) and in structures associated with compassion and self-awareness.

The investigators also found that participant-reported reductions in stress were associated with decreased gray matter density in the amygdala, which plays a role in anxiety and stress.

None of these brain structure changes were seen in the control group.

“It is fascinating to see the brain’s plasticity and that, by practicing meditation, we can play an active role in changing the brain and can increase our well-being and quality of life,” first author Britta Holzel, a research fellow at Massachusetts General Hospital (MGH) in Boston and Giessen University in Germany, said in an MGH news release.

The findings, which will be published in the Jan. 30 issue of the journal Psychiatry Research: Neuroimaging, are the latest in the growing field of research about the benefits of meditation.
