冥想练习改变了默认模式网络（DMN）中的内在静息状态功能连接（rsFC）。然而，关于冥想对其他静息态网络的影响，人们知之甚少。本研究的目的是探讨冥想经验和冥想状态功能连接对多个静息状态网络的影响。冥想练习者（MP）进行了两次5分钟的扫描，一次在休息时，一次在冥想时。一个未经冥想的对照组（CG）进行了一次静息状态扫描。对冥想练习年限与rsFC和msFC之间的关系进行了探索性回归分析。在静息状态下，MP相比CG表现出更大的rsFC内的背侧注意网络（DAN）。在MP，冥想，相比于休息，加强FC之间的DAN和DMN和显着性网络，而它减少FC之间的DAN，背内侧PFC，和DAN。回归分析显示，冥想经验的年数和msFC之间的DAN，丘脑，顶前沟，而DAN，外侧和上级顶叶，和颞叶之间的负相关。这些研究结果表明，冥想的练习加强了DAN内的FC，并加强了参与注意力、自我参照过程和情感反应的分布式网络之间的耦合。
Meditation practice alters intrinsic resting-state functional connectivity (rsFC) in the default mode network (DMN). However, little is known regarding the effects of meditation on other resting-state networks. The aim of current study was to investigate the effects of meditation experience and meditation-state functional connectivity (msFC) on multiple resting-state networks (RSNs). Meditation practitioners (MPs) performed two 5-minute scans, one during rest, one while meditating. A meditation naïve control group (CG) underwent one resting-state scan. Exploratory regression analyses of the relations between years of meditation practice and rsFC and msFC were conducted. During resting-state, MP as compared to CG exhibited greater rsFC within the Dorsal Attention Network (DAN). Among MP, meditation, as compared to rest, strengthened FC between the DAN and DMN and Salience network whereas it decreased FC between the DAN, dorsal medial PFC, and insula. Regression analyses revealed positive correlations between the number of years of meditation experience and msFC between DAN, thalamus, and anterior parietal sulcus, whereas negative correlations between DAN, lateral and superior parietal, and insula. These findings suggest that the practice of meditation strengthens FC within the DAN as well as strengthens the coupling between distributed networks that are involved in attention, self-referential processes, and affective response.
