I'm not well versed with reading research papers etc but I have one question. Could it be possible that by simply practicing mindfulness meditation the brain restructured itself via a placebo style effect rather that because of the meditation itself? For anybody who has access to the paper what did the control group do during the eight weeks?
The paper doesn't seem to be available, but the abstract at the author's page[0] says "Healthy but stressed individuals are randomized to either a meditation-based stress reduction intervention or health education control intervention."
