A longitudinal study of the effect of short-term meditation training on functional network organization of the aging brain

Abstract The beneficial effects of meditation on preserving age-related changes in cognitive functioning are well established. Yet, the neural underpinnings of these positive effects have not been fully unveiled. This study employed a prospective longitudinal design, and graph-based analysis, to stu...
