虽然针灸越来越多地用于医学治疗，但其作用机制仍不确定。我们使用经颅磁刺激技术来证明运动皮层兴奋性的侧化效应。右侧运动皮质兴奋性降低，左侧运动皮质兴奋性倾向相反。假针插入未引起运动皮质兴奋性的显著变化。这些发现为皮层兴奋性调节提供了新的神经生理学证据，补充了功能性神经影像学研究的结果。
Although acupuncture is increasingly utilized for medical therapy, its mechanism of action remains uncertain. We used transcranial magnetic stimulation to demonstrate lateralized effects of motor cortex excitability with this technique. Right-sided reduction in motor cortex excitability and a tendency to the opposite effect on the left side was seen with acupuncture. Sham needle insertions did not result in significant changes of motor cortex excitability. These findings provide new neurophysiological evidence of cortical excitability modulation complementary to findings derived from functional neuroimaging studies.
