以前的研究表明，长期（数月到数年）的正念冥想练习会诱导灰质的结构可塑性。然而，目前还不清楚新手的短期（<30天）正念冥想是否会引起类似的结构变化。我们之前的随机对照试验（RCT）确定了前扣带皮层（ACC）和后扣带皮层（PCC）周围的白色变化在2 - 4周内，经过5-10小时的正念训练。此外，这些变化与健康成年人的情绪状态有关。PCC是冥想和其他透视过程中涉及的功能解剖学的关键枢纽。因此，在这项采用随机设计的纵向研究中，我们研究了10小时正念训练的效果，与主动控制放松训练（RT）相比，身心一体化训练（IBMT）对PCC灰质体积的影响。我们发现，简短的IBMT增加腹侧PCC体积和基线气质特征，个体差异的指数与减少训练诱导的灰质增加。我们的研究结果表明，短暂的正念冥想诱导灰质可塑性，这表明腹侧PCC的结构变化-与自我意识，情感，认知和衰老相关的关键枢纽-可能对预防情绪相关的疾病和衰老相关的认知下降具有重要意义。
Previous studies suggest that the practice of long-term (months to years) mindfulness meditation induces structural plasticity in gray matter. However, it remains unknown whether short-term (<30 days) mindfulness meditation in novices could induce similar structural changes. Our previous randomized controlled trials (RCTs) identified white matter changes surrounding the anterior cingulate cortex (ACC) and the posterior cingulate cortex (PCC) within 2 to 4 weeks, following 5-10 h of mindfulness training. Furthermore, these changes were correlated with emotional states in healthy adults. The PCC is a key hub in the functional anatomy implicated in meditation and other perspectival processes. In this longitudinal study using a randomized design, we therefore examined the effect of a 10 h of mindfulness training, the Integrative Body-Mind Training (IBMT) on gray matter volume of the PCC compared to an active control—relaxation training (RT). We found that brief IBMT increased ventral PCC volume and that baseline temperamental trait—an index of individual differences was associated with a reduction in training-induced gray matter increases. Our findings indicate that brief mindfulness meditation induces gray matter plasticity, suggesting that structural changes in ventral PCC—a key hub associated with self-awareness, emotion, cognition, and aging—may have important implications for protecting against mood-related disorders and aging-related cognitive declines.
