Soviet research showed human blood vessels can be conditioned to respond to electromagnetic fields, proving measurable physiological EMF effects.

Plain English Summary

Summary written for general audiences

Soviet researchers investigated whether humans could develop conditioned reflexes to high-frequency electromagnetic fields by measuring vascular responses using plethysmography. This study examined if blood vessel changes could be trained to occur in response to EMF exposure, suggesting the body's circulatory system can detect and respond to electromagnetic field changes. The research represents early evidence that EMF exposure triggers measurable physiological responses in humans.

Why This Matters

This Soviet-era research represents a fascinating early investigation into how the human body responds to electromagnetic fields at the vascular level. The fact that researchers could establish conditioned reflexes to EMF exposure suggests our circulatory system is far more sensitive to electromagnetic changes than previously understood. This has profound implications for modern EMF exposure, where we're constantly bathed in radiofrequency radiation from cell phones, WiFi, and wireless devices. If our blood vessels can be conditioned to respond to EMF changes, it raises important questions about how chronic, low-level exposure might affect cardiovascular function over time. The study's use of plethysmography to measure vascular responses provides objective evidence that EMF exposure creates detectable physiological changes, countering industry claims that non-thermal EMF effects don't exist.

In the tests described we obtained clear-cut conditioned-reflex conception of the vessels. However, can one affirm that the conditioned stimulus here was the change in electromagnetic field intensity and not an accompanying stimulus? Inasmuch as the subject was situated in an isolated chamber, concomitant contact stimuli were excluded in the same manner as visual and olfactory stimuli. Hence, the only channel for the arrival of a parasitic signal could be noise. The acoustic insulation of the chamber was not complete and the sound of the switched-on diathermy apparatus was perceived by the subject at the threshold of audibility. However, the supply of the stimulus -- rotation of the apparatus, application of the wire, and extension of the hand -- did not for practical purposes alter the pitch, volume or timbre of the sound emitted from the switched-on apparatus. At least the man sitting alongside the apparatus was unable to detect any changes in the nature of the sounds. Hence, the arrival of information along a sound channel can also be excluded with all likelihood. Temperature and electrical channels might also have indirectly carried a signal, i.e., with the change in field intensity on metallic objects (the copper coil, parts of clothing) electrical currents might have been induced which, in turn, could have evoked either a direct effect on the body or an elevation of temperature of metallic objects and a temperature effect. However, calculations indicate that temperature elevations of metallic parts with a change in field within the limits of 100 microvolts/m would be several orders less than the usual temperature fluctuations and the induced currents would be several times less than the subject's own biological currents and significantly below the level of the noises created by radio stations, industrial installations, and so on. Accordingly, analysis of all the possible pathways for the arrival of a signal leads to the conclusion that in these tests a change in the intensity of a high frequency electromagnetic field was evidently the conditioned stimulus. With respect to the mechanism for the reception of this signal, we can only express the hypotheses: 1) the receptors for the electromagnetic field are the end structures of known organs of sensation (the optic retina, skin endings, etc.); 2) there are specific receptors for it (for example, in the skin); 3) the electromagnetic field is perceived by any living cell, particularly, by nerve cells of the brain. It is also very possible that the field acts indirectly on the cells, by producing fine physico-chemical changes in the internal environment of the body, and secondarily affecting interoceptors. In this case, the mechanism for the reception of an electromagnetic field may be analogous to the perception of weak doses of ionizing radiation and the field assumes the role of a non-specific, inadequate stimulus. However, further research is necessary to elucidate the mechanism of its action.

Quick Questions About This Study

Yes, this Soviet research demonstrated that human vascular systems can develop conditioned reflexes to high-frequency electromagnetic field exposure, measured through plethysmography techniques that detect blood vessel changes.
Plethysmography is a measurement technique that detects changes in blood volume within blood vessels. In this study, researchers used it to objectively measure how electromagnetic field exposure affected human vascular responses.
A vascular conditioned reflex means blood vessels learn to automatically respond to a stimulus. This research showed human circulatory systems could be trained to react to electromagnetic field changes through repeated exposure.
Soviet researchers investigated whether electromagnetic fields could trigger measurable physiological responses in humans. Blood vessel changes provided objective evidence that the body detects and responds to EMF exposure at the circulatory level.
Yes, by demonstrating conditioned vascular reflexes to electromagnetic fields, this study provides early evidence that EMF exposure creates detectable, measurable changes in human physiology through the circulatory system.
