基于正念的冥想练习涉及各种注意力技能，包括维持和集中注意力的能力。在简单的正念呼吸练习中，需要持续的注意力来保持对呼吸的关注，同时需要认知控制来检测走神。因此，我们假设定期、简短的正念训练将改善注意力的自我调节，并促进与注意力控制相关的神经元活动的变化。进行了纵向随机对照组脑电图研究。在基线 (T1) 时，40 名从未接触过冥想的参与者被随机分为等待组和冥想组，他们接受了三个小时的正念冥想训练。最终剩下二十八名参与者。在 T1、8 周后 (T2) 和 16 周后 (T3)，所有参与者执行计算机化 Stroop 任务（注意力控制的测量），同时记录 64 通道脑电图。在 T1 和 T3 之间，冥想者被要求每天冥想 10 分钟。事件相关电位 (ERP) 分析强调了在 16 周的正念训练过程中产生的两个组间效应。刺激后 160-240 毫秒左右后位点的早期效果表明冥想练习改善了注意力资源的集中。刺激后 310-380 毫秒在中央后部部位的第二个效应反映了冥想练习减少了物体识别过程中资源的募集，特别是对于不一致的刺激。头皮地形图和源分析（可变分辨率电磁断层扫描，VARETA）表明神经源的相关变化，早期效应涉及左侧枕颞内侧和外侧区域，后期效应涉及右侧枕颞和下颞区域。结果表明，正念冥想可能会改变认知资源分配的效率，从而改善注意力的自我调节。
Mindfulness-based meditation practices involve various attentional skills, including the ability to sustain and focus ones attention. During a simple mindful breathing practice, sustained attention is required to maintain focus on the breath while cognitive control is required to detect mind wandering. We thus hypothesized that regular, brief mindfulness training would result in improvements in the self-regulation of attention and foster changes in neuronal activity related to attentional control. A longitudinal randomized control group EEG study was conducted. At baseline (T1), 40 meditation naïve participants were randomized into a wait list group and a meditation group, who received three hours mindfulness meditation training. Twenty-eight participants remained in the final analysis. At T1, after eight weeks (T2) and after 16 weeks (T3), all participants performed a computerized Stroop task (a measure of attentional control) while the 64-channel EEG was recorded. Between T1 and T3 the meditators were requested to meditate daily for 10 min. Event-related potential (ERP) analysis highlighted two between group effects that developed over the course of the 16-week mindfulness training. An early effect at left and right posterior sites 160–240 ms post-stimulus indicated that meditation practice improved the focusing of attentional resources. A second effect at central posterior sites 310–380 ms post-stimulus reflects that meditation practice reduced the recruitment of resources during object recognition processes, especially for incongruent stimuli. Scalp topographies and source analyses (Variable Resolution Electromagnetic Tomography, VARETA) indicate relevant changes in neural sources, pertaining to left medial and lateral occipitotemporal areas for the early effect and right lateral occipitotemporal and inferior temporal areas for the later effect. The results suggest that mindfulness meditation may alter the efficiency of allocating cognitive resources, leading to improved self-regulation of attention.
