A meta-analysis of twelve studies (226 mindfulness participants, 204 controls) found that mindfulness training increased resting-state functional connectivity between the left middle cingulate cortex (part of the salience network) and the posterior cingulate cortex (a hub of the default mode network), compared to control conditions. This effect, though small (Hedge's g = 0.234), was statistically significant and showed low heterogeneity across studies. The result supports the idea that mindfulness training enhances communication between brain networks involved in flexible, internally-oriented attentional control. No evidence of publication bias was detected.
