前扣带皮层（ACC）是与自我调节发展有关的网络的一部分，其连接性在发展过程中发生巨大变化。在之前的研究中，我们表明，基于中医的 3 小时心理训练（身心综合训练，IBMT）可以增加 ACC 活性并改善自我调节。然而，尚不清楚白质连接性的变化是否可以由少量的心理训练引起。我们在此报道，11 小时的 IBMT 增加了分数各向异性 (FA)，该指数表明辐射冠中白质的完整性和效率，辐射冠是连接 ACC 与其他结构的重要白质束。因此，IBMT 可以提供一种改善自我调节的方法，或许还可以减少或预防各种精神障碍。
The anterior cingulate cortex (ACC) is part of a network implicated in the development of self-regulation and whose connectivity changes dramatically in development. In previous studies we showed that 3 h of mental training, based on traditional Chinese medicine (integrative body–mind training, IBMT), increases ACC activity and improves self-regulation. However, it is not known whether changes in white matter connectivity can result from small amounts of mental training. We here report that 11 h of IBMT increases fractional anisotropy (FA), an index indicating the integrity and efficiency of white matter in the corona radiata, an important white-matter tract connecting the ACC to other structures. Thus IBMT could provide a means for improving self-regulation and perhaps reducing or preventing various mental disorders.
