Research - MRI Acupuncture Research on Point Specificity

electro acupunctureResearchers from the Department of Medicine at the University of California, Irvine, recently noted that a hemodynamic study of acupoint P6 showed that this acupuncture point “decreased heart rate and increased the high-frequency HRV index of cardiac vagal modulation….”

In the report, it also concluded "Recent evidence shows that stimulation of different points on the body causes distinct responses in hemodynamic, fMRI and central neural electrophysiological responses. Brain imaging studies have shown that stimulation of different points elicits unique brain patterns that also are disease-specific. While fMRI studies show that different regions of the brain are activated, these studies do not show the pathways through which these changes occur. Laboratory studies of point specificity have demonstrated that stimulation of underlying neural pathways connecting variably to regions of the brain leads to differential physiological and clinical responses. However, because of our limited knowledge of the mechanisms underlying point specificity, further studies in this area are warranted."
