Abstract : With the purpose of studying the effect of a high-frequency field on the nervous system, 34 persons (24 men and 10 women) working in an environment with strong sources of centimeter electromagnetic waves were examined plethysmographically. Vascular reactions were induced by stimulation in the standard combination: multiplication by heart, electrical skin touch, audio stimulation (bell), deep breath. Vascular reactions on the fingers were recorded by an electrocapacitive plethysmograph (2 plethysmograms from the contralateral fingers + a pneumogram). The results support the opinion that registered deviations in vascular-tonus control are caused by a long-time action of a high-frequency field on the neuro-vascular system.
