在选择性注意期间，类似于7-14 Hz的α节律在早期感觉皮层中被调制，这表明这些动态在感知中的机械作用。在这里，我们调查了是否可以通过“正念”冥想（MM）来增强α调制，MM是一种训练练习者持续关注身体和呼吸相关感觉的计划。我们假设，与对照组的参与者相比，MM组的参与者将在初级体感新皮层的局部表征中表现出增强的α功率调制。健康受试者被随机分配到8周的MM训练组或对照组。使用脑磁图（MEG）记录SI手指代表，我们发现冥想者表现出增强的阿尔法功率调制响应线索。这一发现首次显示了持续注意力训练后增强的局部α调制，并暗示了这种形式的增强动态神经调节在冥想练习的行为效应中。(C)2011 Elsevier Inc.

During selective attention, similar to 7-14 Hz alpha rhythms are modulated in early sensory cortices, suggesting a mechanistic role for these dynamics in perception. Here, we investigated whether alpha modulation can be enhanced by "mindfulness" meditation (MM), a program training practitioners in sustained attention to body and breath-related sensations. We hypothesized that participants in the MM group would exhibit enhanced alpha power modulation in a localized representation in the primary somatosensory neocortex in response to a cue, as compared to participants in the control group. Healthy subjects were randomized to 8-weeks of MM training or a control group. Using magnetoencephalographic (MEG) recording of the SI finger representation, we found meditators demonstrated enhanced alpha power modulation in response to a cue. This finding is the first to show enhanced local alpha modulation following sustained attentional training, and implicates this form of enhanced dynamic neural regulation in the behavioral effects of meditative practice.
