The effects of qi-gong and acupuncture on human cerebral evoked potentials and electroencephalogram.
Although a number of studies on traditional Chinese medicine, such as qi-gong (QG), acupuncture (AC), moxibustion and Chinese herbal drugs, have been reported in recent years, there are few reports on human cerebral evoked potentials (EPs), especially relating only to QG and AC. In the present study, we examined the changes in EPs and electroencephalogram (EEG) by QG, and by AC stimulation to the point called "Zusanli" on the left lower leg, with one healthy male adult. 1. With regard to the effect of QG, significant changes in EP-components originated from the cortex suggest both facilitating and inhibitory effects of QG on the cortex. However, no significant changes in EP-components originated from the subcortex and no significant changes in EEG power% suggest that QG does not affect the subcortex. 2. With regard to the effects of AC, significant changes in EP-components originated from the cortex suggest facilitating and inhibitory effects of AC stimulation on the cortex. Furthermore, it is suggested that AC stimulation has few effects on the somatosensory and the visual pathways up to the cortex, while it has complicated effects on the auditory pathway up to the cortex.
