Researchers from Yale, Harvard, Massachusetts General Hospital, and the Massachusetts Institute of Technology found that meditating regularly can cause increased cortical thickness in the brain. Participants were regular Buddhist Insight meditators who meditated for forty minutes each day on average. Their brain images displayed cortical regions of greater thickness than those of non-meditators, in areas of the brain associated with sensory, auditory, visual, and internal perception. Increased cortical thickness benefits heart rate and breathing, and is predicted to slow aging of the frontal cortex. Researchers suspect that meditation as well as other mind-body exercises like yoga can increase the amount of gray matter in anyone’s brain.
