目的：本研究的目的是利用静息态功能磁共振成像（rs-fMRI）研究为期8天的密集的三夜冥想计划对大脑功能连接的影响。研究方法：13名Samyama项目参与者（冥想者）和4名对照者在为期8天的住宅冥想项目前后接受了fMRI脑部扫描。受试者在休息时和集中呼吸时接受了血氧水平依赖（BOLD）对比的fMRI。评估了Samyama计划前后网络连接的变化。此外，经验证的心理指标与功能连接的变化相关。结果如下：冥想者在Samyama程序后显着增加了显着网络（SN）和默认模式网络（DMN）之间的网络连接（p <0.01）。SN内连接的增加与自我报告的正念分数的改善相关（p <0.01）。结论：Samyama是一种密集的沉默冥想计划，它有利地增加了显著性和默认模式网络之间的静息状态功能连接。在专注观察呼吸的过程中，冥想者在特定网络中的内部网络连接较低。此外，增加的网络内连接与Samyama后自我报告的正念改善相关。临床试验注册：[www.example.com]，标识符：[NCT 04366544]。于2020年4月17日注册。
Purpose: The purpose of this study was to investigate the effect of an intensive 8-day Samyama meditation program on the brain functional connectivity using resting-state functional MRI (rs-fMRI). Methods: Thirteen Samyama program participants (meditators) and 4 controls underwent fMRI brain scans before and after the 8-day residential meditation program. Subjects underwent fMRI with a blood oxygen level dependent (BOLD) contrast at rest and during focused breathing. Changes in network connectivity before and after Samyama program were evaluated. In addition, validated psychological metrics were correlated with changes in functional connectivity. Results: Meditators showed significantly increased network connectivity between the salience network (SN) and default mode network (DMN) after the Samyama program (p < 0.01). Increased connectivity within the SN correlated with an improvement in self-reported mindfulness scores (p < 0.01). Conclusion: Samyama, an intensive silent meditation program, favorably increased the resting-state functional connectivity between the salience and default mode networks. During focused breath watching, meditators had lower intra-network connectivity in specific networks. Furthermore, increased intra-network connectivity correlated with improved self-reported mindfulness after Samyama.
