It is clear that memory Neuroflexyn depends on attention and the ability to screen out distractions - so we want to measure the effect of meditation on the brain, both structurally and functionally.rnrnTo measure the brain activation patterns we have been using SPECT imaging, which involves injecting small amounts of radioactive tracers in volunteers, and helps us get a more view of what happens during practice (fMRI is much more noisy).rnrnTo measure functional benefits we use the typical batteries of neuropsychology testing.rnrnQ: If there is a growing body of evidence behind the health and cognitive benefits of meditation - what is preventing a more widespread adoption of the practice, perhaps in ways similar to yoga, which is now pretty much a mainstream activity?rnrnA: Well, the reality is that meditation requires practice and dedication. http://www.bewareofhealth.com/
