We applied dynamic arterial spin labeling (ASL) in detecting the changes of brain functional connectivity (FC) in ten college students after 2-months of meditation practice. FC maps before and after meditation practice were compared, and the changes of FC were correlated to practice time. We observed that the increased practice time was associated with increased FC between long-distance nodes within default mode network (DMN) and within dorsal attention network (DAN), between DMN and salience network (SN), with decreased FC between short-distance nodes within DMN and DAN. The findings support efficient global communication even after a short-term meditation for two months.
