OBJECTIVE: To investigate the effects of manual acupuncture at Shenmen (HT7) or Taiyuan (LU9) on the attention function of the brain, and to lay an experimental foundation for researching brain function and integration mechanisms of the human brain in relation to acupuncture stimulation.
METHODS: Ten healthy young college students were selected as experimental subjects. P3a and P3b potentials were induced by novel stimulation and target stimulation with vision and were observed using Neuroscan event-related potentials system at time windows of ms 330-430 or 400-600 ms for observing the change of intensity distribution of P300 after manual acupuncture at HT7 or LU9.
RESULTS: The amplitude of P3a and P3b decreased significantly after manual acupuncture at HT7 or LU9, but the degree of decreases affected by the acupoints was different. The decrease of the amplitude of P3a due to acupuncture at HT7 was more significant than acupuncture at LU9 (P<0.05).
CONCLUSION: The attention function of the brain is affected by manual acupuncture at HT7 or LU9 and manual acupuncture at HT7 has a greater influence on the attention function of the brain.

1. I have to show appreciation to this wtrier just for bailing me out of this trouble. Right after browsing throughout the world-wide-web and coming across techniques which are not powerful, I assumed my life was well over. Being alive without the strategies to the problems you have resolved through your main blog post is a crucial case, and ones which could have badly damaged my career if I hadn't come across your website. Your primary mastery and kindness in taking care of the whole lot was invaluable. I don't know what I would have done if I had not come across such a thing like this. It's possible to at this moment relish my future. Thanks so much for your impressive and effective guide. I won't think twice to recommend your web sites to any individual who should get tips about this subject matter. (2012-5-13 0:00:00)
