“The finding of a reduced rate of decline with age of both global and regional gray matter volume in meditators may in fact indicate the involvement of multiple mechanisms of neuroprotection.”
“Regular practice of meditation is associated with increased thickness in a subset of cortical regions related to somatosensory, auditory, visual and interoceptive processing. Further, regular meditation practice may slow age-related thinning of the frontal cortex.”
