Researchers at UCLA found that those who practiced meditation for years showed stronger brain connections, less aging in the brain over time, and less brain size shrinkage. The results of the study suggest that practicing meditation regularly may slow down natural withering of brain structure, as well as positively affecting our immune system. The study used diffusion tensor imaging to measure the changes in participants’ brains, revealing a difference in more than one cerebral area. The findings suggest the presence of connections that enhance the relay of rapid electrical signals across different brain regions, indicating that meditation is all encompassing in its positive effects on the brain. With the slower aging of their brains, meditators are able to maintain many cognitive abilities for longer.
