PULSE POINTS RESEARCH: Meditation Can Significantly Change the Brain n a study entitled “Meditation Experience is Associated with Increased Cortical Thickness,” researchers discovered that meditation does not only help to reduce stress, but can also change the brain’s gray matter, a major part of the central nervous system that is associated with memory and processing information. Research participants were asked to take part in an eightweek Mindfulness-Based Stress Reduction program. Using MRIs, the brain activities of the participants were measured before and after the program. According to Dr. Sara Lazar, one of the research authors and a neuroscientist at Massachusetts General Hospital as well as professor at Harvard Medical School, research data showed that, after eight weeks of meditation, meditators have an I increased amount of gray matter in four regions of the brain, namely: 1. Posterior cingulate – involved in mind-wandering and self-relevance 2. Left hippocampus – in learning, cognition, memory and emotional regulation 3. Temporo parietal junction (TPJ) – associated with perspective-taking, empathy and compassion 4. Pons – an area of the brain stem where regulatory neurotransmitters are produced In addition, the research further discovered that the amygdala, the fight or flight part of the brain which is important for anxiety, fear and stress, decreased in size among participants who went through the mindfulness-based stress reduction program.
