利用脑磁图初步探讨针刺足三里穴的脑功能变化

摘要

目的：探讨应用针刺足三里穴脑磁图成像的实验方法，寻找针刺足三里穴引起脑功能变化的实验依据。方法：通过对5例健康志愿者行针刺右侧足三里穴，记录脑磁图（ MEG）的变化，结合脑部核磁共振仪（ MRI）的定位，并与足三里穴旁非经非穴、刺前与刺后进行对照，观察针刺对脑神经生理功能的影响。结果：根据实时脑磁图及颅脑核磁共振图像定位资料，认为针刺足三里穴的体感刺激诱发脑部生物磁场源在大脑中央后回，并传导至边缘系统。结论：脑磁图检测对循经感传的经络研究具有一定特异性。%Objective:To study the experimental method of acupuncture at ST36( Zusanli) point by MEG,and to find the experimental basis of that for brain function changes.Me thods:Acupuncture was used to stimulate the right ST36 point among 5 healthy volunteers, recording the changes of MEG combined with the location of cerebral MRI, and compare the non-acupoint near ST36 point as well as before and after acupuncture,and then observe the effect of acupuncture therapy on cerebral physiological function.Results:According to the data of the MEG and the located portraits of the cerebral MRI, the brain biomagnetic field source was inducted by the feeling incitement of acupuncture and ST36 point was considered in the cerebral postcentral gyrus and it was conducted to limbic system.Conclusion:There are certain particularities that the MEG-examination is used for the study of SPM.
