Meditation Directly Affects the Function and Structure of the Brain

From “How to Get Smarter, One Breath at a Time,” by Lisa Takeuchi Cullen, Time.com (1.10.06):

Everyone around the water cooler knows that meditation reduces stress. But with the aid of advanced brain scanning technology, researchers are beginning to show that meditation directly affects the function and structure of the brain, changing it in ways that appear to increase attention span, sharpen focus and improve memory.

Visual area correlated with meditation experience. Statistical map depicting cortical thickness correlated with change in respiration rate. One recent study found evidence that the daily practice of meditation thickened the parts of the brain's cerebral cortex responsible for decision making, attention and memory. Sara Lazar, a research scientist at Massachusetts General Hospital, presented preliminary results last November that showed that the gray matter of 20 men and women who meditated for just 40 minutes a day was thicker than that of people who did not. Unlike in previous studies focusing on Buddhist monks, the subjects were Boston-area workers practicing a Western-style of meditation called mindfulness or insight meditation. "We showed for the first time that you don't have to do it all day for similar results," says Lazar. What's more, her research suggests that meditation may slow the natural thinning of that section of the cortex that occurs with age.
