Objective  

To observe the conditions of the activating areas in the brain evoked by needling Shenmen (HT 7) acupoint.

Methods  

Twelve healthy young volunteers were needled at Shenmen (HT 7) acupoint with rotating and twisting techniques. Functional magnetic resonance imaging (fMRI) was adopted to detect the brain activating areas, TR/TE/FA=3560 ms/50 ms/90°. After scanning, the images were dealt with SPM2.

Results  

Needling Shenmen (HT 7) primarily activated BA2 and BA1 of the gyrus postcentralis in right-sided frontal lobe, BA47 of left-sided inferior frontal gyrus and BA43 of left-sided gyrus postcentralis, and also activated BA40 of inferior parietal lobule in right-sided parietal lobe, BA22 of gyrus temporalis superior in left-sided lobus temporalis, and BA40 of right-sided insula; however, the sham acupoints could not activate these nucleus.

Conclusion  

Needling Shenmen (HT 7) can activate the relevant functional areas in the brain.

目的  

观察针刺心经神门穴的脑激活区情况。

方法  

选取健康青年志愿者12 例, 采用fMRI组块模式。 fMRI的主要参数为TR/TE/FA=3560 ms/50 ms/90°, 刺激为手法捻转行针。 扫描后图像使用SPM2 进行后处理。

结果  

神门穴主要激活了右侧额叶的中央后回BA2、 BA1, 左侧额下回BA47 和中央后回BA43, 其次为右侧顶叶的顶下小叶BA40, 左侧颞叶的颞上回BA22, 右侧脑岛BA40。 而假穴没有激活。

结论  

刺激神门穴能激活相应的脑功能区。
