New research looks at the effects of studying a form of meditation on brain connectivity. Writing in the Proceedings of the National Academy of Science, researchers in China and the University of Oregon describe experiments on 45 students, some of whom were taught a meditation technique known as integrative body-mind training (IBMT). The researchers used brain imaging techniques to examine fibers connecting brain regions before and after training. Students trained in the IBMT approach for 11 hours or more appeared to develop new fibers in a part of the brain that helps a person regulate behavior. Control subjects did not form the new fibers. But what does the presence of those fibers actually mean -- and what is the meditation technique doing? We'll talk about it.
