*Study shows practice may have potential to change brain’s physical structure*

Two years ago, researchers at UCLA found that specific regions in the brains of long-term meditators were larger and had more gray matter than the brains of individuals in a control group. This suggested that meditation may indeed be good for all of us since, alas, our brains shrink naturally with age.

Now, a follow-up study suggests that people who meditate also have stronger connections between brain regions and show less age-related brain atrophy. Having stronger connections influences the ability to rapidly relay electrical signals in the brain. And significantly, these effects are evident throughout the entire brain, not just in specific areas. (more…)

Zen meditation has many health benefits, including a reduced sensitivity to pain. According to new research from the Université de Montréal, meditators do feel pain but they simply don’t dwell on it as much. These findings, published in the month’s issue of Pain, may have implications for chronic pain sufferers, such as those with arthritis, back pain or cancer.

“Our previous research found that Zen meditators have lower pain sensitivity. The aim of the current study was to determine how they are achieving this,” says senior author Pierre Rainville, researcher at the Université de Montréal and the Institut universitaire de gériatrie de Montréal. “Using functional magnetic resonance imaging, we demonstrated that although the meditators were aware of the pain, this sensation wasn’t processed in the part of their brains responsible for appraisal, reasoning or memory formation. We think that they feel the sensations, but cut the process short, refraining from interpretation or labelling of the stimuli as painful.” (more…)
