Fig. 2: Functional magnetic resonance imaging (fMRI) (n = 19 participants).
A Meditation vs. rest RSN functional connectivity pre- and post-intervention. Cell values and color scale represent Cohen’s d effect size values from paired t-tests. Asterisks denote pFWE < 0.05 significance (28 multiple comparisons). ECN (executive control network), DMN (default mode network), DAN (dorsal attention network), SN (salience network), SMN (somatomotor network), VN (visual network), and AN (auditory network). B Meditation vs. rest RSN-region functional connectivity pre- and post-intervention. Cell values and color scale represent Cohen’s d effect size values from paired t-tests. Asterisks denote pFWE < 0.05 (630 multiple comparisons). C Significant (p < 0.05) meditation-induced functional connectivity changes between a priori ROIs pre- and post-intervention. Color scale represents Cohen’s d effect sizes from paired t-tests. D Whole-cortex/brain network measures for 48-region Harvard-Oxford cortical atlas and Power (2011) 264-region brain atlas (n = 19). Asterisks denote * (p < 0.05), ** (p < 0.01), *** (p < 0.001), **** (p < 0.0001). E Anatomical Structure. Coronal and axial views with superior parietal lobule cluster (yellow), where advanced practitioners had greater gray matter volume than novices at baseline.
