Title: Mindfulness practice leads to increases in regional brain grey matter density

Summary: An investigation into the neural mechanisms underpinning that may be impacted by the Mindfulness Based Stress Reduction (MBSR) form of mindfulness meditation.  Sixteen participants with no prior experience of meditation were put through an eight-week MSBR training programme. Any observed changes to grey matter concentration within the MBSR group were investigated and compared to a control group. Analyses indicated the MBSR group experienced increased grey matter in the left hippocampus, posterior cingulate cortex, the temporo-parietal junction and the cerebellum. These findings suggest a potential relationship between the practice of MBSR and changes to the concentration of grey matter in parts of the brain connected to learning and memory processes, emotion regulation, self-referential processing, as well as perspective-taking. The number of participants in the control group is low (16), so replication with a larger number of people is essential. It would also be interesting to know if any parts of the brain suffered reduced concentration of grey matter.
