| 摘 要： | 目的：观察针刺健康志愿者右侧外关穴和非穴时不同脑区的激活情况。探讨针刺外关穴对脑的激活效应。方法：16例健康志愿者，随机分为外关穴组和非穴组，分别针刺右侧外关穴和非穴；同时，运用GE1．5T超导核磁共振系统完成脑部fMRI扫描，所得数据采用感兴趣区（ROI）法进行处理和分析。结果：针刺外关穴和非穴，对双侧顶叶、额叶、枕叶、颞叶、基底节区、扣带回、海马、小脑、脑桥等多个脑区分别有不同程度的激活；ROIs激活几率和激活点数比较表明，针刺外关穴对右侧小脑的激活大于非穴（P〈0．01）；激活强度统计表明，针刺外关穴与非穴对于各脑区的激活强度没有显著性差异（P〉0．05）。结论：与“非穴”比较，针刺外关穴能相对特异地激活小脑，该效应与外关穴临床功效的中枢机制有关。
