Methods： EA was applied at volunteers＇ right LI4 （of 9 subjects in the LI4 group） and facial non-acupoint points （of 5 subjects in the control group）, and whole brain 3-dimensional T1 anatomical imaging of high resolution 1 × 1 × 1 mm^3 used was performed with clustered stimulatory mode adopted by BOLD fMRI. Pretreatment and statistical t-test were conducted on the data by SPM2 software, then the statistical parameters were superimposed to the 3-dimensional anatomical imaging. Results： Data from 3 testees of the 9 subjects in the LI4 group were given up eventually because they were unfit to the demand due to different causes such as movement of patients＇ location or machinery factors. Statistical analysis showed that signal activation or deactivation was found in multiple cerebral areas in 6 subjects of LI4 group and 5 subjects of the control group （P〈0.01）. In the LI4 group, the areas which showed signal activation were： midline nuclear group of thalamus, left supra marginal gyrus, left supra temporal gyrus, right precuneous lobe, bilateral temporal pole, left precentral gyrus and left cerebellum; those which showed signal deactivation were： bilateral hippocampus, parahippocampal gyrus, amygdala body area, rostral side/audal side of cingulate gyrus, prefrontal lobe and occipital lobe as well as left infratemporal gyrus. In the control group, areas which showed signal activation were： bilateral frontal lobe, postcentral gyrus, Reil＇s island lobe, primary somato-sensory cortex, cingulate gyrus, superior temporal gyrus, occipital c展开更多
