In Chinese medical thinking, Yin meridians do not pass through the brain leading to the belief that their stimulation would not yield brain activation. Yet, pericardium meridian, a Yin meridian, and brain functions constitute a functional unit. We postulate that stimulation of PE 6 in the pericardium meridian would induce brain activation. 14 normal right-handed male subjects were studied using fMRI with manual acupuncture and electrical acupuncture, respectively. We observed brain activation following stimulation of PE 6 in the superior temporal gyrus and superior longitudinal fasciculus bilaterally as well as in the medial area of the frontal gyrus.
