Changes of electrodermal properties in the "acupuncture points" on men and rats.

Jakoubek B, RohlÃcek V.

The measurements of skin resistance to electrical current performed in rats and men indicated the occurrence of small skin areas, in which the conductivity for DC and AC was sharply increased. In healthy men, the anatomical localization of these areas of increased skin conductivity (AISC) corresponded to the localization of the so-called "acupuncture points" (AP). In patients, the AISC were also found outside the ordinary AP, mainly in areas of referred pain. The measurements of the size of AISC by multiple electrodes indicated the approximate size of AISC cca 350 microM in the rat, ccs 450 microns in man. The recording of skin conductivity were taken from : a) AISC in man and the rat, b) skin in the close neighbourhood of AISC, c) from the sweating human skin.
