[Measurement of the human skin electrical potentials in the tibial projection region]

Skin electrical potentials (EP) were measured in the region of the medial tibia projection in human subjects in the ordinary state and after 4 days of bed rest. The intent was to determine if there is an interaction of the slow electrical activity of visceral organs and tissues with the electrical activity of the basal epithelium which, according to the author's hypothesis, controls some of the mammalian body functions. EP values were found to depend on positioning of electrodes relative to the bone proximal epiphysis. This dependence yielded a non-linear curve. Individual EP curves were relatively stable. Evidence was obtained that 4-d bed rest caused a significant decline in the electrical activity in the region of the skin tibia projection.
