Researchers have known for decades that meditation can improve someone’s physical and mental health. It can relieve stress, lower blood pressure and lift someone’s mood, But only in the last few years have neuroscientists taken a serious loook at the changes in brain structure underlying some of meditation’s benefits. Like everything else, we do meditation rewires our neural circuits, Pruning away the least used connections and strengthening the ones we exercise most
Studies looking for signs of these changes usually focus on “ mindfulness meditation”, which challenges people to keep their attention fixed on the thoughts and sensations. In the present moment, Scientists aknowledge that these studies are small and not ideally designed, but at this point researchers have gathered enough evidence to be confident that their findings are not just flukes. Experiments suggest that Buddhist monks have really robust connections between scattered regions of their brains, which allows for more synchronized. Communication. Expert meditators also seem to develop an especially wrinkly cortex, the brain’s outer layer. We depend on the cortex for many of our most sophisticated mental abilities like abstract thought and introspection.
Several studies have confirmed that meditation can increase the volume and density of the hippocampus a seahorse- shaped area of the brain in the middle of the skull. That is absolutely crucial for memory.
And although areas of the brain responsible for sustaining attention usually shrink, as we age meditation counteracts this decay, An increasing number of studies show that meditating for as little as 12 to 20 minutes a day for several weeks can sharpen the mind In these studies. Meditators have scored higher on tests of attention and working memory, which is the ability to temporarily store and manipulate information in one’s mind. Some lifelong meditators in their 50s and 60s can even outperform twenty-somethings in tests of visual attention.
