I wonder how possible it is to permanently damage the brain without physically impacting it or rooting around in there. There are studies that show visible changes in the amygdala and other structures in the brain after 8 weeks of 15 minutes per day of mindfullness meditation for instance. One "side effect" of it for me has been noticeable memory improvements. The brain changes in response to stimuli for sure, but the changes may be reversible.
