磁刺激光明穴产生脑组织电信号的变化

SICENCE新闻发布作者：张欣稿号：NRR-34-13磁刺激光明穴产生脑组织电信号的变化中国河北工业大学所在课题组进行关于针刺、电刺激和磁刺激的一项研究，利用磁刺激线圈对正常人体左侧光明穴（GB37）进行重复脉冲磁刺激并观测脑电信号，与非穴位点磁刺激的脑电信号进行对比，并同时对比磁刺激光明穴前、中、后视觉刺激产生的脑电信号差异。结果显示磁刺激正常人光明穴对脑图电信号影响显著，其机制可能与顶区、中央区和右颞区脑图电信号样本熵值变化显著有关，样本熵值的变化可以有效的区分不同生理状态下的脑图电信号。实验结果数据发表在《中国神经再生研究（英文版）》杂志2014年3月第5期。正常人脑图电信号处理的样本熵信息图19通道分布图Article:Analysisoftheeffectofrepeated-pulsetranscranialmagneticstimulationattheGuangmingpointonelectroencephalograms,byXinZhang1,LingdiFu2,YuehuaGeng2,XiangZhai3,YanhuaLiu4(1TianjinPolytechnicUniversity,Tianjin,China;2Province-MinistryJointKeyLaboratoryofElectromagneticFieldandElectricalApparatusReliability,HebeiUniversityofTechnology,Tianjin,China;3DepartmentofOtorhinolaryngology,TianjinHuanhuHospital,Tianjin,China;4HebeiCollegeofIndustryandTechnology,Shijiazhuang,HebeiProvince,China)ZhangX,FuLD,GengYH,ZhaiX,LiuYH.Analysisoftheeffectofrepeated-pulsetranscranialmagneticstimulationattheGuangmingpointonelectroencephalograms.NeuralRegenRes.2014;9(5):549-554.欲获更多资讯：NeuralRegenResSICENCE新闻发布作者：张欣稿号：NRR-34-13Effectofrepeated-pulsetranscranialmagneticstimulationattheGuangmingpointonEEGsInarecentstudyreportedintheNeuralRegenerationResearch(Vol.9,No.5,2014),repeated-pulsetranscranialmagneticstimulationwasadministeredtohealthypeopleattheleftGuangming(GB37)andamockpoint,andcalculatedthesampleentropyofelectroencephalogramsignalsusingnonlineardynamics.Additionally,researcherscomparedelectroencephalogramsampleentropyofsignalsinresponsetovisualstimulationbefore,during,andafterrepeated-pulsetranscranialmagneticstimulationattheGuangming.Resultsshowedthatrepeated-pulsetranscranialmagneticstimulationattheGuangmingevokesdifferentpatternsofelectroencephalogramsignalsthanrepeated-pulsetranscranialmagneticstimulationatothernearbypointsonthebodysurface,andthatrepeated-pulsetranscranialmagneticstimulationattheGuangmingisassociatedwithchangesinthecomplexityofvisuallyevokedelectroencephalogramsignalsinparietalregions,centralgyrus,andtemporalregions.Distributionofthe19channelsusedtoplottheelectroencephalogramsignalsample-entropymap.Article:Analysisoftheeffectofrepeated-pulsetranscranialmagneticstimulationattheGuangmingpointonelectroencephalograms,byXinZhang1,LingdiFu2,YuehuaGeng2,XiangZhai3,YanhuaLiu4(1TianjinPolytechnicUniversity,Tianjin,China;2Province-MinistryJointKeyLaboratoryofElectromagneticFieldandElectricalApparatusReliability,HebeiUniversityofTechnology,Tianjin,China;3DepartmentofOtorhinolaryngology,TianjinHuanhuHospital,Tianjin,China;4HebeiCollegeofIndustryandTechnology,Shijiazhuang,HebeiProvince,China)ZhangX,FuLD,GengYH,ZhaiX,LiuYH.Analysisoftheeffectofrepeated-pulsetranscranialmagneticstimulationattheGuangmingpointonelectroencephalograms.NeuralRegenRes.2014;9(5):549-554.
