Electrical Characterization of Proposed Transpositional Acupoints on the Urinary Bladder Meridian in a Rat Model

Figure 1

Points investigated to determine the electrical characteristics on the back in a rat. The points include transpositional acupoints of the BL meridian on the back (red circles) and nonacupoints even though those were located on the path of the BL meridian on the back (blue squares). The electrical voltages were compared to values for corresponding reference points (X). C1: atlas, T1: 1st thoracic vertebra, L1: 1st lumbar vertebra, S: sacrum, Gray bar: vertebra from T1 to S (midline of the back), 1st (1st BL line, the longitudinal line extending from the middle point between the 2nd BL line and the midline of the back), 2nd (2nd BL line, the longitudinal line extending from the end of the atlas wing), and R (the line of reference points, 4 mm to the right of the 2nd BL line).
