Abstract

The purpose of this experiment is to find the methods of visualizing the effects of acupuncture. The limbs are main five areas of Q´i. Therefore, the activation of Qi in these areas can have an effect on the trunk and the sensory gans. Ji-Eum(BL67) is known to have special relationship to the eyes and optical functions. Based on this theory. :hose 10 volunteers, first I compared visual activation and no visual activation, and next I look at the acupuncture imulation at BL67 and no acupuncture stimulation. The first experiment was conducted with light to the eyes using pecker board 8Flz flash and observed the time course data. Next I stimulated BL67 using the same time course iradigm as I did during the visual stimulation. The results of acupuncture stimulation were distinct and shoved much rilarity to the result of visual stimulation. The cerebral cortex is composed of almost only neuronal cell bodies, and e sensory signals at any part of the body are transferred along the nervous system to the brain. But the signal ranges at the visual cortex which were stimulated through acupuncture of BL67 cannot be explained through the mronal pathway of acupuncture pain signal. Therefore It suggests that this phenomenon occur due to another echanism which might give a hint to the still unknown mechanism of Meridian. As a control group, stimulation of )n-acupoint has been performed, but there were no clear changes at the brain cortex. This leads to the conclusion gat this stimulation of the visual cortex is done specifically through stimulation of BL67.
The results of This experiment are like this:
1. Visual stimulation through checker board 8Hz flash induced 6.940.74 % positive signal changes at the visual )rtex of the brain.
2. Acupuncture stimulation at BL67 induced 6.580.59% negative signal changes at the visual cortex of the brain.
3. Acupuncture stimulation at Non-acupoint did not induce any significant signal changes at the same area.
