AB  - Mindfulness refers to attending to moment-to-moment experiences with acceptance 
      and no judgment. Several scales have been developed to quantify different 
      components of mindfulness. The Mindful Attention Awareness Scale (MAAS) is 
      particularly sensitive to trait mindfulness and is proposed to measure the 
      attentional component of mindfulness. The purpose of this study was to identify 
      the neural correlates of the MAAS in four resting-state networks related to 
      attention-the default mode network (DMN), the salience network (SN), and the left 
      and right central executive network (CEN). Thirty-two university students naive 
      to mindfulness completed the MAAS and later underwent a resting-state functional 
      magnetic resonance imaging scan. Resting-state data were analyzed using an 
      independent component analysis; the scores from the MAAS were covaried to the 
      connectivity maps in an analysis of covariance. The results indicate that 
      variations in MAAS scores correlated with variations in functional connectivity 
      patterns in resting-state networks. Specifically, within the SN and CEN, the MAAS 
      was negatively correlated with functional connectivity in the precuneus, even 
      though the precuneus is a key component of the DMN. Negative correlations in the 
      DMN between the MAAS and the insula and negative correlations in the SN between 
      the MAAS and the posterior cingulate cortex were also observed. These results 
      suggest that MAAS scores (1) are correlated with the functional connectivity of 
      several brain structures related to attention and (2) involve cross-network 
      functional connectivity.
