摘　　要：目的比较电针刺激光明穴时对人体体表循经红外辐射轨迹(IRRTM)和大脑皮层第一体觉区(SI)功能活动的影响,探讨IRRTM与皮层体觉诱发电位地形图(CSEP)变化的内在联系。方法应用红外热像和脑诱发电位地形图技术,观察48名健康志愿者的IRRTM和CSEP的变化。结果①电针刺激对经脉循行线上的温度影响不大,但对轨迹的影响比较清楚,它可使IRRTM变得更加连续和规整;②电针刺激感传显著者,当循经感传沿胆经路线上传至头面部时,大脑皮层体觉诱发反应地形图除了在靠近中线的下肢代表显示1个红色高电位反应外,越过了上肢代表区,在外侧端的面部代表区又出现1个红色的高电位反应区。结论电针刺激光明穴产生的IRRTM及在大脑皮层所形成的CSEP,再次证实了外周动因激发是产生循经感传现象的决定因素。Objective To compare the changes of infrared radiant track along meridian courses （IRRTM） and functional activities of primary somatosensory area （SI） of cerebral cortex during electroacupunc- ture at Guangming （GB37） and explore the immanent relation between 1RRTM and cortical somatosensory e- voked potential （CSEP）. Methods 48 healthy adult volunteers were selected as observation objects, and the changes of IRRTM and CSEP were observed by infrared thermal imaging technique and topographical tech- nique of brain evoked potential. Results Electroacupuncture had little effect on the temperature of meridi- an, but had clear effect on IRRTM. E｜ectroacupuneture induced infrared radiant track to be more continuous and regular. For volunteers with remarkable sensation transmission along gall bladder meridian to head and face, high potential reactions in the lower limbs and face occurreded in the CSEP skipping the upper limbs. Conclusion IRRTM and CSEP occurred when GB37 is stimulated by electroacupuncture, and the results confirm again that peripheral tissue evoking is the decisive factor for transmission along the meridia.
