从情绪挑战中恢复和对负面影响的容忍度增加都是心理健康的标志。正念训练（MT）已被证明可以促进这些结果，但对其作用机制知之甚少。本研究采用功能性磁共振成像（fMRI）比较神经反应悲伤的挑衅参与者完成8周的MT和候补对照。悲伤导致大脑皮层中线沿着与自我参照过程相关的区域被广泛招募。尽管自我报告的悲伤程度相当，但MT参与者表现出明显的神经反应，右侧招募更多，包括与身体感觉相关的内脏和躯体感觉区域。MT组在诱发悲伤时观察到的更大的躯体募集与抑郁评分降低相关。恢复情感和感觉神经网络之间的平衡-支持基于概念和身体的情感表征-可能是正念减少焦虑反应脆弱性的一条途径。
Recovery from emotional challenge and increased tolerance of negative affect are both hallmarks of mental health. Mindfulness training (MT) has been shown to facilitate these outcomes, yet little is known about its mechanisms of action. The present study employed functional MRI (fMRI) to compare neural reactivity to sadness provocation in participants completing 8 weeks of MT and waitlisted controls. Sadness resulted in widespread recruitment of regions associated with self-referential processes along the cortical midline. Despite equivalent self-reported sadness, MT participants demonstrated a distinct neural response, with greater right-lateralized recruitment, including visceral and somatosensory areas associated with body sensation. The greater somatic recruitment observed in the MT group during evoked sadness was associated with decreased depression scores. Restoring balance between affective and sensory neural networks—supporting conceptual and body based representations of emotion— could be one path through which mindfulness reduces vulnerability to dysphoric reactivity.
