A noted 2005 study by Sara Lazar, Ph.D., an instructor in psychiatry at Harvard Medical School, aimed to find out which parts of the brain become active when a person practices mindfulness and meditation. Her team studied 20 people who meditate regularly and 20 who don’t. The results were astounding: Brain regions associated with attention, sensory awareness and emotional processing — the cortex — were thicker in meditators. In fact, meditators’ brains grew thicker in direct correlation with how much they meditated. The findings suggest that meditation can change the brain’s structure — perhaps because certain brain regions are used more frequently in the process of meditation, and therefore grow. Lazar says it’s a “huge, huge, huge” leap to assert that meditators’ brains function better. “We really don’t know how meditation works,” Lazar cautions, stressing that scientists are merely uncovering “pieces of the puzzle.” Yet for anyone accustomed to waiting for a chorus of nods from scie
