Study shows compassion meditation changes the brain

MADISON - Can we train ourselves to be compassionate" A new study suggests the answer is yes. Cultivating compassion and kindness through meditation affects brain regions that can make a person more empathetic to other peoples' mental states, say researchers at the University of Wisconsin-Madison.

Published March 26 in the Public Library of Science One, the study was the first to use functional magnetic resonance imaging (fMRI) to indicate that positive emotions such as loving-kindness and compassion can be learned in the same way as playing a musical instrument or being proficient in a sport. The scans revealed that brain circuits used to detect emotions and feelings were dramatically changed in subjects who had extensive experience practicing compassion meditation.

The research suggests that individuals - from children who may engage in bullying to people prone to recurring depression - and society in general could benefit from such meditative practices, says study director Richard Davidson, professor of psychiatry and psychology at UW-Madison and an expert on imaging the effects of meditation. Davidson and UW-Madison associate scientist Antoine Lutz were co-principal investigators on the project.

The study was part of the researchers' ongoing investigations with a group of Tibetan monks and lay practitioners who have practiced meditation for a minimum of 10,000 hours. In this case, Lutz and Davidson worked with 16 monks who have cultivated compassion meditation practices. Sixteen age-matched controls with no previous training were taught the fundamentals of compassion meditation two weeks before the brain scanning took place.

"Many contemplative traditions speak of loving-kindness as the wish for happiness for others and of compassion as the wish to relieve others' suffering. Loving-kindness and compassion are central to the Dalai Lama's philosophy and mission," says Davidson, who has worked extensively with the Tibetan Buddhist leader. "We wanted to see how this voluntary generation of compassion affects the brain systems involved in empathy."

Various techniques are used in compassion meditation, and the training can take years of practice. The controls in this study were asked first to concentrate on loved ones, wishing them well-being and freedom from suffering. After some training, they then were asked to generate such feelings toward all beings without thinking specifically about anyone.

Each of the 32 subjects was placed in the fMRI scanner at the UW-Madison Waisman Center for Brain Imaging, which Davidson directs, and was asked to either begin compassion meditation or refrain from it. During each state, subjects were exposed to negative and positive human vocalizations designed to evoke empathic responses as well as neutral vocalizations: sounds of a distressed woman, a baby laughing and background restaurant noise.

"We used audio instead of visual challenges so that meditators could keep their eyes slightly open but not focused on any visual stimulus, as is typical of this practice," explains Lutz.
