集中注意力冥想（FAM）是一种基本的冥想练习，可以培养注意力控制和监控技能。横断面研究强调了经验丰富的冥想者的高认知能力和辨别性神经活动。然而，神经活动变化与冥想训练引起的注意力改善之间的直接关系仍有待阐明。为了调查这一点，我们进行了一项纵向研究，评估了非冥想者在进行 8 周 FAM 训练之前和之后的三刺激奇怪任务、静息状态和 FAM 期间的脑电图 (EEG) 结果。与对照组 (n = 20) 相比，FAM 训练组 (n = 17) 在奇怪的任务中表现出明显更高的 P3 振幅，并且对目标刺激的反应时间 (RT) 更短。此外，观察到 FAM 期间的 F4-Oz theta 带相位同步指数 (PSI) 与奇怪任务期间的 P3 振幅之间存在显着负相关，而 FAM 期间的 F4-Pz theta 带相位同步指数 (PSI) 与奇怪任务期间的 P3 振幅之间存在显着正相关。相反，在对照组中没有观察到这些相关性。这些发现提供了 FAM 训练有效性的直接证据，并有助于我们理解冥想对大脑活动和认知表现影响的机制。
Focused attention meditation (FAM) is a basic meditation practice that cultivates attentional control and monitoring skills. Cross-sectional studies have highlighted high cognitive performance and discriminative neural activity in experienced meditators. However, a direct relationship between neural activity changes and improvement of attention caused by meditation training remains to be elucidated. To investigate this, we conducted a longitudinal study, which evaluated the results of electroencephalography (EEG) during three-stimulus oddball task, resting state and FAM before and after 8 weeks of FAM training in non-meditators. The FAM training group (n = 17) showed significantly higher P3 amplitude during the oddball task and shorter reaction time (RT) for target stimuli compared to that of the control group (n = 20). Furthermore, a significant negative correlation between F4-Oz theta band phase synchrony index (PSI) during FAM and P3 amplitude during the oddball task and a significant positive correlation between F4-Pz theta band PSI during FAM and P3 amplitude during the oddball task were observed. In contrast, these correlations were not observed in the control group. These findings provide direct evidence of the effectiveness of FAM training and contribute to our understanding of the mechanisms underpinning the effects of meditation on brain activity and cognitive performance.
