Mindfulness is an intervention that was used in many psychiatry treatments. In this study, the subject experienced two different states: (1) attention (i.e., listening to a podcast) and (2) mindfulness (i.e., meditation). Twenty-two students were included in a Mindfulness-Based Stress Reduction (MBSR) course with EEG recording sessions on week four and week six. Brain dynamics were investigated to elucidate the complexity and connectivity of the brain. The alpha PSD increased in all brain areas during mindfulness in both weeks. For complexity, Fractal Dimension (FD) increased significantly during meditation in the week six recording. When comparing the FD in the mindfulness state of week four and week six, we also witnessed a significant increase in the following week. The coherence of the interhemispheric frontal and temporal regions increased significantly in both weeks. In conclusion, the subject successfully transferred from attention to mindfulness, demonstrated by the alpha changes when going from podcast to meditating. An enhancement in brain complexity was found, suggesting an augmentation in cognitive function. Finally, the coherence exhibits strengthened connections in the frontal area.
正念是一种在许多精神病学治疗中使用的干预方法。在本研究中，受试者经历了两种不同状态：（1）注意力状态（即听播客）和（2）正念状态（即冥想）。22名学生参加了基于正念的减压（MBSR）课程，并在第四周和第六周进行了脑电图记录。研究脑动力学以阐明大脑的复杂性和连通性。在这两周的正念状态下，所有脑区的α频段功率谱密度（PSD）均增加。关于复杂性，在第六周记录的冥想过程中，分形维数（FD）显著增加。比较第四周和第六周正念状态下的FD时，我们也发现下一周有显著增加。在这两周中，半球间额叶和颞叶区域的相干性均显著增加。总之，受试者成功地从注意力状态转变为正念状态，从听播客转变为冥想时α波的变化证明了这一点。发现大脑复杂性增强，表明认知功能增强。最后，相干性表明额叶区域的连接增强。
