Scalp acupuncture (SA) combines the concept of cerebral cortex organization with the principles of acupuncture. The SA stimulates sections of the cerebral cortex. We studied the functional modulation of the left hand sensorimotor area induced by SA in order to investigate the specificity of the SA-related functional effects of the middle 2/5 of the MS6 line of the left side, which corresponds to the upper limb motor segment of the primary motor area. To this purpose, we compared the pre- and post-SA functional activation patterns during an implicit motor imagery task (handedness decision in which participants simulated rotational hand movements) and an explicit manual motor execution task. Feet and mouth movements, and the fMRI changes in their respective representations were used as control conditions. Only SA on the hand area of the left side (as compared to the mouth and the foot representations which were used as control conditions) exerted a release effect on the right hand area. In addition, an increased activation of the superior parietal lobe was seen, which is involved in movement control and planning. Taken together, these preliminary findings may shed light on the SA effects and confirm a prolonged effect of SA even after cessation of needling stimulation.
头皮针疗法（SA）将大脑皮质组织的概念与针灸原理相结合。头皮针刺激大脑皮质的各个区域。我们研究了头皮针诱导的左手感觉运动区的功能调制，以探讨左侧MS6线中间2/5（对应于初级运动区的上肢运动段）与头皮针相关的功能效应的特异性。为此，我们比较了头皮针前后在一项隐性运动想象任务（参与者模拟手部旋转运动的利手判断）和一项显性手动运动执行任务中的功能激活模式。足部和口部运动及其各自表征的功能磁共振成像变化用作对照条件。只有左侧手部区域的头皮针（与用作对照条件的口部和足部表征相比）对右侧手部区域产生了释放效应。此外，还观察到顶上叶的激活增加，该区域参与运动控制和规划。综上所述，这些初步发现可能有助于阐明头皮针的效应，并证实即使在针刺刺激停止后头皮针仍有延长效应。
