Meditation May Help the Brain ‘Turn Down the Volume’ on Distractions

ScienceDaily (Apr. 21, 2011) — The positive effects of mindfulness meditation on pain and working memory may result from an improved ability to regulate a crucial brain wave called the alpha rhythm. This rhythm is thought to “turn down the volume” on distracting information, which suggests that a key value of meditation may be helping the brain deal with an often-overstimulating world.

Researchers from Massachusetts General Hospital (MGH), Harvard Medical School and the Massachusetts Institute of Technology report that modulation of the alpha rhythm in response to attention-directing cues was faster and significantly more enhanced among study participants who completed an eight-week mindfulness meditation program than in a control group. The report will appear in the journal Brain Research Bulletin and has been released online.

“Mindfulness meditation has been reported to enhance numerous mental abilities, including rapid memory recall,” says Catherine Kerr, PhD, of the Martinos Center for Biomedical Imaging at MGH and the Osher Research Center at Harvard Medical School, co-lead author of the report. “Our discovery that mindfulness meditators more quickly adjusted the brain wave that screens out distraction could explain their superior ability to rapidly remember and incorporate new facts.”

Mindfulness Meditation Changes Decision-Making Process

ScienceDaily (Apr. 21, 2011) — If a friend or relative won $100 and then offered you a few dollars, would you accept this windfall? The logical answer would seem to be, sure, why not? “But human decision making does not always appear rational,” said Read Montague, professor of physics at Virginia Tech and director of the Human Neuroimaging Laboratory at the Virginia Tech Carilion Research Institute.

According to research conducted over the last three decades; only about one-fourth of us would say, “Sure. Thanks.” The rest would say, “But that’s not fair. You have lots. Why are you only giving me a few?” In fact, people will even turn down any reward rather than accept an ‘unfair’ share.

Unless they are Buddhist meditators, in which case — fair or not — more than half will take what is offered, according to new research by Ulrich Kirk, research assistant professor with the Human Neuroimaging Laboratory at Virginia Tech; Jonathan Downar, assistant professor with the Neuropsychiatry Clinic and the Centre for Addition and Mental Health at the University of Toronto; and Montague, published in the April 2011 issue of Frontiers in Decision Neuroscience.

Their research shows that Buddhist meditators use different areas of the brain than other people when confronted with unfair choices, enabling them to make decisions rationally rather than emotionally. The meditators had trained their brains to function differently and make better choices in certain situations.

The research “highlights the clinically and socially important possibility that sustained training in mindfulness meditation may impact distinct domains of human decision making,” the researchers write.

The research came about when Montague wondered whether some people are capable of ignoring the social consideration of fairness and can appreciate a reward based on its intrinsic qualities alone. “That is,” he said, “can they uncouple emotional reaction from their actual behavior?”
