正念對心理健康之影響： 事件關聯電位與功能性磁共振造影之近期研究回顧

The Effects of Mindfulness on Mental Health: A Review of Recent Studies on Event-Related Potentials and Functional Magnetic Resonance Imaging

本研究目的在回顧近期有關正念對心理健康之研究，並進一步觀察事件關聯電位與功能性磁共振造影之影響。結果顯示在正念介入後或正念傾向較高的個體與較佳之心理健康有關。另在事件關聯電位之研究分析顯示正念不僅與行為表現有正向關聯，甚至在N1、N2、 P2、P3、LPP等大腦電位上亦有顯著影響。而在功能性磁共振造影上，經由正念介入後對於腦島、前扣帶皮質層等大腦結構亦有顯著效益。有鑒於此，正念對於神經電生理與大腦結構活化均有正向的關聯。相對而言，我國仍未探討正念對於神經電生理與大腦結構活化之影響，然而先前研究大多採用情緒相關認知測驗以觀察受試者之大腦電位潛在歷程與大腦活化狀態，因此期許未來能持續探討正念之不同類型課程、不同認知測驗之影響，並採用事件關聯電位或功能性磁共振造影持續探討其潛在機制。

 

The purpose of this study was to review the relationships of mindfulness and mental health on event-related potentials (ERP) and functional magnetic resonance imaging (fMRI). Results show that better mental health is consistently correlated with the effects of mindfulness interventions or higher individual dispositions of mindfulness. Studies demonstrate that mindfulness not only positively correlates with behavioral performance, it also has positive correlations with different ERPs (such as N1, N2, P2, P3, and LPP). Similar positive effects were also observed in activation of different brain structures, including the insula and the anterior cingulate gyrus. At present, our own research context (in Taiwan) has yet to more systematically explore the effects of mindfulness on neurophysiology or the activation of brain structures. However, previous research has often already used emotion-related cognitive tests to observe ERPs and conduct fMRI scans. Therefore, the authors suggest that future research should further explore different types of mindfulness interventions and cognitive tasks while continuing to use ERP or fMRI methods to research the underlying mechanisms.
