Positron emission tomography (PET) is used to observe the cerebral function widely and is a good method to explore the mechanism of acupuncture treatment on the central nervous system. By using this method, we observed the cerebral function of 6 patients suffering from ischemic stroke after receiving EA treatment at Baihui(GV20) and right Qubin(GB7). The results were: (1) the glucose metabolism changed significantly on primary motor area (M1), premotor cortex (PMC), and superior parietal louble (LPs) bilaterally, as well as the Supplementary Motor Area (SMA) on the unaffected hemisphere right after the first EA treatment. (2) The glucose metabolism on bilateral M1 and LPs changed significantly after three weeks of daily EA treatments. (3) The glucose metabolism on other areas such as insula, putamen, and cerebellum changed significantly. It demonstrated that EA at Qubin and Baihui couldactivate the cerebral structures related to motor function on the bilateral hemispheres.We concluded that EA was very helpful for the cerebral motor plasticity after the ischemic stroke. Also based on this study we assumed that the brain plasticity should be a network and that acupuncture participated in some sections of this course.
正电子发射断层扫描（PET）被广泛用于观察大脑功能，是探索针刺治疗中枢神经系统机制的一种很好的方法。通过这种方法，我们观察了 6 例缺血性中风患者接受电针治疗百会（GV20）和右曲鬓（GB7）后大脑的功能。结果如下：（1）第一次电针治疗后，大脑初级运动区（M1）、运动前区（PMC）和顶叶上回（LPs）双侧以及健侧辅助运动区（SMA）的葡萄糖代谢明显改变。（2） 经过三周的每日电针治疗，双侧 M1 和 LPs 的葡萄糖代谢明显改变。（3） 岛叶、壳核和小脑等其他区域的葡萄糖代谢也发生了明显变化。结果表明，电针曲鬓和百会可以激活双侧与运动功能相关的大脑结构。我们得出结论，电针治疗对缺血性中风后的大脑运动可塑性非常有帮助。也基于这项研究，我们假设脑可塑性应该是一个网络，而针刺参与了这个过程的一些部分。
