Laplace plane analysis of impedance between acupuncture points H-3 and H-4.

Reichmanis M, Marino AA, Becker RO.

The frequency dependence of the skin impedance between two acupuncture points (H-3 and H-4) was determined by Laplace plane analysis of the time domain response to an input voltage perturbation. Both the resistance and capacitance between the acupuncture points differed significantly from the corresponding controls, thus supporting the interpretation of the acupuncture system as an information transfer network.
