A study on a new brain activating procedure using transcutaneous xenon light irradiation around the stellate ganglion

本研究的目的是探讨经皮氙灯照射星状神经节周围作为一种非侵入性脑激活程序的可能性。53名健康志愿者接受了两组实验：1)以合适的仰卧位（Xe-SGI）照射双侧星状神经节周围10分钟；2)在与Xe-SGI（对照组）相同的位置休息10分钟。结果，很明显，Xe-SGI不仅引起交感神经抑制，而且引起觉醒和注意力下降。综上所述，Xe-SGI不能作为一种非侵入性的脑激活程序。

The purpose of this study was to investigate the possibility of transcutaneous xenon light irradiation around the stellate ganglion as a non-invasive brain activating procedure. 53 healthy volunteers who were enrolled in this study underwent two experimental sessions : 1) 10-minute xenon light irradiation around the bilateral stellate ganglions in a suitable supine position (Xe-SGI); 2) 10-minute rest in the same position as Xe-SGI (control). As a result, it becomes obvious that Xe-SGI causes not only sympathetic suppression but also decreased arousal and attention. In conclusion, Xe-SGI can not be used as a non-invasive brain activating procedure.
