Compassion meditation may boost neural basis of empathy

The idea behind the compassion-based meditation is that "the feelings we have about people can be trained in optimal ways," says Lobsang Tenzin Negi, who developed the protocol.

A compassion-based meditation program can significantly improve a person’s ability to read the facial expressions of others, finds a study published by Social Cognitive and Affective Neuroscience. This boost in empathic accuracy was detected through both behavioral testing of the study participants and through functional magnetic resonance imaging (fMRI) scans of their brain activity.

“It’s an intriguing result, suggesting that a behavioral intervention could enhance a key aspect of empathy,” says lead author Jennifer Mascaro, a post-doctoral fellow in anthropology at Emory University. “Previous research has shown that both children and adults who are better at reading the emotional expressions of others have better relationships.”

The meditation protocol, known as Cognitively-Based Compassion Training, or CBCT, was developed at Emory by study co-author Lobsang Tenzin Negi, director of the Emory-Tibet Partnership. Although derived from ancient Tibetan Buddhist practices, the CBCT program is secular in content and presentation.

The research team also included senior author Charles Raison, formerly a psychiatrist at Emory’s School of Medicine and currently at the University of Arizona, and Emory anthropologist James Rilling.

Research shows that people better at reading the emotions of others have better relationships.

When most people think of meditation, they think of a style known as “mindfulness,” in which practitioners seek to improve their ability to concentrate and to be non-judgmentally aware of their thoughts and feelings. While CBCT includes these mindfulness elements, the practice focuses more specifically on training people to analyze and reinterpret their relationships with others.

“The idea is that the feelings we have about people can be trained in optimal ways,” Negi explains. “CBCT aims to condition one’s mind to recognize how we are all inter-dependent, and that everybody desires to be happy and free from suffering at a deep level.”

Study participants were healthy adults without prior meditation experience. Thirteen participants randomized to CBCT meditation completed regular weekly training sessions and at-home practice for eight weeks. Eight randomized control subjects did not meditate, but instead completed health discussion classes that covered mind-body subjects like the effects of exercise and stress on well-being.

To test empathic accuracy before and following CBCT, all participants received fMRI brain scans while completing a modified version of the Reading the Mind in the Eyes Test (RMET). The RMET consists of black-and-white photographs that show just the eye region of people making various expressions. Those being tested must judge what the person in the photograph is thinking or feeling. 

Eight out of the 13 participants in the CBCT meditation group improved their RMET scores by an average of 4.6 percent, while the control participants showed no increase, and in the majority of cases, a decrease in correct answers for the RMET.

The meditators, in comparison to those in the control group, also had significant increases in neural activity in areas of the brain important for empathy, including the inferior frontal gyrus and dorsomedial prefrontal cortex. These changes in brain activity accounted for changes in the empathic accuracy scores of the participants.

“These findings raise the intriguing possibility that CBCT may have enhanced empathic abilities by increasing activity in parts of the brain that are of central importance for our ability to recognize the emotional states of others,” Raison says. “An important next step will be to evaluate the effects of CBCT on diverse populations that may particularly benefit from enhanced empathic accuracy, such as those suffering from high-functioning autism or severe depression.”

Findings from the current study add to a growing database indicating that the CBCT style of meditation may have physical and emotional effects relevant to health and well-being. For example, previous research at Emory found that practicing CBCT reduced emotional distress and enhanced physical resilience in response to stress in both healthy young adults and in high-risk adolescents in foster care.

Ig Nobel Prizes give cheeky nod to science


Emory primatologist Frans de Waal can add to his long list of honors the 2012 Ig Nobel Prize for Anatomy, for a study about how chimpanzees can identify other individual chimpanzees simply from looking at photographs of their rear ends. Here's a link to the 2008 study: "Faces and Behinds: Chimpanzee Sex Perception."

The Ig Nobel Prizes are handed out each year at Harvard University to recognize research "that first makes you laugh, then makes you think." The Guardian provides a great summary of this year's winners.

Scientific American's Scicurious Brain blog reports that de Waal was happy to win an Ig Nobel Prize, because scientists tend to take themselves too seriously. Scicurious Brain notes that the chimpanzee study was actually less about their butts and more about "gender constructs" and how chimpanzees recognize one another: "What they found that was chimps could easily match the sample butt to the sample face and showed good sex matching, but ONLY in the case of chimps that they knew personally. When it came to the random Facebook friend request, the chimps couldn’t match butt to face."

The drama over water



Water is now known as the new oil. Blue gold. The axis resource on which the development of all others turns. That humble liquid gushing out of your tap is a strategic commodity, the subject of a U.S. intelligence report that warns of a rising risk of political unrest and war over its increasingly scarce supply worldwide.

It’s also a theatrical headliner. A dance-for-camera drama called “Bend” explores our relationship to water, a relationship set to change dramatically in the face of climate change and other pressures. The video, above, shows a preview of the project, created by Lori Teague, choreographer and director of Emory’s Dance Program, and her husband, Mark Teague, videographer and stage manager at the Schwartz Center.

The public is invited to free, special showings of “Bend” on Thursday, September 27, at 7 pm, 8:30 pm and 10 pm in the Dance Studio of the Schwartz Center. Click here for details.

West Nile virus detected in metro-Atlanta mosquitoes and birds

A total of 3,142 human cases of West Nile virus in the United States, including 134 deaths, have been reported to the CDC so far this year.

Emory students trap mosquitoes for testing.
Cooler weather may reduce the spread of the mosquito-borne virus, but we’re not out of the woods yet. Students from Emory’s Department of Environmental Studies West Nile virus lab are finding a high number of mosquitoes infected with the virus in metro Atlanta parks.

Some birds infected with the virus have also been found in the lab's research sites, including Tanyard Creek Park and Grant Park, says Uriel Kitron, a disease ecologist and chair of the Department of Environmental Studies.

The mosquito that transmits West Nile virus is an evening mosquito, coming out an hour before sunset and staying active through the night, Kitron told Channel 2 Action News.

Measuring the healing power of touch



Many people agree that getting a massage makes them feel good. Researchers at Emory University are now quantifying the biological benefits of frequent massage, with the aim of developing potential therapies.

"We really don't know the precise biology of massage right now, but what I can tell you is this: Even in normal individuals, we're able to decrease the production of stress hormones," says Mark Hyman Rapaport, chair of Emory's Department of Psychiatry and Behavioral Sciences. "What we're able to demonstrate now is that repeated massage has an added effect." Watch the video, above to learn more.

The research is funded by the National Center for Complementary and Alternative Medicine, part of the National Institutes of Health.

"The only way we're going to discern what goes on with complementary or alternative treatments," Rapaport says, "is if an impartial funding agency like the federal government is involved in investigating whether there are true biological, beneficial effects associated with these atypical interventions. There may be many different ways to help individuals."
