摘要

主要目的是研究长期冥想练习对情感性图片观看过程中事件相关脑电位(erp)的影响。与对照组(N = 20)相反，冥想者(N = 20)在中潜伏期(200-400 ms)右半球的ERP阳性并没有表现出与觉醒相关的增加。我们还发现，在同一时间窗口中，无论图像效价如何，冥想者在中央区域都有更强的ERP负性。我们假设长期的冥想练习增强了前额自上而下的控制，而不是快速自动检测刺激的显著性。

[The Influence of Long-Term Meditation Practice on Early Emotional Processing in the Brain: an ERP Study].

The main aim was to study effects of long-term meditation practice on event-related brain potentials (ERPs) during affective picture viewing. The meditators' (N = 20), contrary to control (N = 20), did not demonstrate arousal-related increases in the mid-latency (200-400 ms) ERP positivity over the right hemisphere. We also found in the same time window stronger ERP negativity for meditators over central regions, regardless of picture valence. We assume that long-term meditation practice enhances frontal top-down control over fast automatic detection of stimulus salience.
