正念冥想专注于当下的体验，让情绪和思想不加评判地传递，这种做法已经被证明对临床人群的各种结果都是有益的。然而，正念运作的基本神经机制以及与新手日常结果的关系仍然未被探索。集中注意力是一种常见的正念感应，从业者专注于特定的身体感觉，通常是呼吸。本研究探讨了这种常见的正念诱导新手从业者的神经机制。健康的新手参与者在功能性磁共振成像（fMRI）过程中完成了一项简短的任务，其中既有注意力[集中呼吸（FB）]，也有控制（非集中注意力）条件。相对于控制条件，FB招募了一个注意网络，包括顶叶和前额叶结构和特质水平的正念在此比较也与顶叶激活。结果表明，一个简短的正念诱导的神经机制与新手的注意过程和特质正念积极调节这种激活。
Mindfulness meditation-the practice of attending to present moment experience and allowing emotions and thoughts to pass without judgment-has shown to be beneficial in clinical populations across diverse outcomes. However, the basic neural mechanisms by which mindfulness operates and relates to everyday outcomes in novices remain unexplored. Focused attention is a common mindfulness induction where practitioners focus on specific physical sensations, typically the breath. The present study explores the neural mechanisms of this common mindfulness induction among novice practitioners. Healthy novice participants completed a brief task with both mindful attention [focused breathing (FB)] and control (unfocused attention) conditions during functional magnetic resonance imaging (fMRI). Relative to the control condition, FB recruited an attention network including parietal and prefrontal structures and trait-level mindfulness during this comparison also correlated with parietal activation. Results suggest that the neural mechanisms of a brief mindfulness induction are related to attention processes in novices and that trait mindfulness positively moderates this activation.
