Abstract
|
|
|
Objective : Recently many studies have showed the evidences of the effect of acupuncture treatment through scientific methods. We performed electro-acupuncture on Taixi(K3) and observed the change of brain activity using fMRI.
Methods : To see the effect of electro-acupuncture stimulation on Taixi(K30, the experiment was carried out on twelve healthy volunteers, using the gradient echo sequence with the 3.0T whole-body fMRI system(ISOL). After the needle insertion on K3, 2Hz of electric stimulation was given for 30 seconds, repeated five times, with 30 second´s intervals.
Result & Conclusions:
Unilateral electro-acupuncture stimulation on K3 increased the brain activity in Brodman Area 8,6,9,13,21,22,38,40,43,2,5,10,20,24,32,34,37,39,41,42. and decreased the brain activity in Brodman Area 9,13,38,22,31,3,6,10,21,25,29,30.
Group Averaged Brain activity induced by Unilateral Electro-acupuncture Stimulation on K3 was increased in Brodman Area 10,22,42,43,44 and was decreased inn Brodman Area 6 and pyrogen test of Bee venom.
Bilateral lectro-acupuncture stimulation on k3 increased the brain activity in Brodman Area 22,3,19,4,13,17,21,41,42,2,5,6,7,18,23,29,30,31,40 and decreased the brain activity in Brodman Area 18,6,39,4,13,2,10,19,36,40,45,46,47.
Group Average brain activity induced by Bilateral Electro-acupuncture Stimulation on K3 was increased in Brodman Area 22,13,4,3,29,38,43 and was decreased in Brodman Area 18,3,19,22,39.
Motor Stimulation activated Brodmann Area 6,43,18.
