外周刺激与磁经皮层刺激（PAS）的重复配对被广泛用于非侵入性地诱导人类运动皮层的可塑性变化。基于PAS诱导的皮质脊髓兴奋性增加与PAS诱导的脊髓F波大小增加之间的对比，人们普遍认为PAS诱导的可塑性起源于皮质。在这里，而不是F波，我们用H反射募集曲线来评估脊髓兴奋性，我们表明，PAS诱导皮质和脊髓兴奋性的平行变化。
Repetitive pairing of a peripheral stimulation with a magnetic transcortical stimulation (PAS) is widely used to induce plastic changes in the human motor cortex noninvasively. Based on the contrast between PAS-induced increase of corticospinal excitability and absence of PAS-induced increase of the spinal F wave size, it has been generally accepted that PAS-induced plasticity is cortical in origin. Here, instead of F waves, we used H reflex recruitment curves to assess spinal excitability, and we demonstrate that PAS induces parallel changes in cortical and spinal excitability.
