Soviet researchers studied ship specialists exposed to microwave radiation and found symptoms resembling adrenal insufficiency, including weakness, fatigue, and low blood pressure. The study examined how the hypothalamic-adrenal system responds to prolonged microwave exposure. This suggests microwave radiation may disrupt the body's stress response system.
Chizhenkova RA · 1967
This 1967 Soviet research examined how rabbit brain tissue responds electrically to various electromagnetic field exposures, measuring changes in brain wave patterns (EEG). The study represents early scientific investigation into how EMF exposure affects neural activity in living animals. While specific findings aren't available, this research contributed to foundational understanding of electromagnetic field interactions with brain tissue.
R. A. CHIZHENKOVA · 1967
Soviet researchers exposed rabbits to magnetic fields and microwave radiation, then measured brain wave changes using EEG technology. They found that both constant magnetic fields (460 oersteds) and microwave frequencies caused distinct brain wave alterations, including increased 'spindles' and slow, high-amplitude waves. Even after surgically removing key brain structures, the electromagnetic effects persisted, suggesting direct brain stimulation rather than reflex responses.

This 1967 conference paper examined how diffuse electrical currents affect human physiological mechanisms, specifically investigating applications for electroanesthesia and electrosleep. The research explored using extremely low frequency electrical fields to induce unconsciousness and sleep states in humans. This represents early scientific investigation into how external electrical fields can directly influence brain function and consciousness.

Researchers in 1967 tested whether electrostatic fields could help monkeys relax before electroanesthesia procedures. They found that 750 volt per centimeter electrostatic fields produced relaxing and mild sleep-inducing effects in monkeys. This suggested a way to reduce the dangerous side effects of electrical anesthesia by using less current.
E. A. Drogichina et al. · 1966
Soviet researchers studied 100 workers exposed to microwave radiation for 10 years, finding progressive nervous system and heart problems. Early symptoms included fatigue, low blood pressure, and slow heart rate, with more severe changes developing over time. This landmark occupational health study demonstrated that prolonged microwave exposure causes measurable health effects in humans.
E. A. Drogichina et al. · 1966
Soviet researchers in 1966 studied 100 people chronically exposed to ultra-high frequency electromagnetic fields, documenting a progression of health effects from mild fatigue to severe cardiovascular problems. The study found that prolonged RF exposure caused increasingly serious symptoms including high blood pressure, blood vessel spasms, and coronary artery problems. This early research provided some of the first clinical evidence that chronic EMF exposure could cause measurable cardiovascular damage in humans.
V. N. Gur'yev, S. M. Kirov · 1965
This 1965 Soviet research examined diencephalic disorders (problems with the brain region controlling hormones and basic functions) in people exposed to prolonged superhigh-frequency electromagnetic fields. The study represents early documentation of neurological effects from microwave radiation exposure in humans. While specific findings aren't available, the research focused on brain dysfunction in the diencephalon, which controls critical functions like sleep, temperature regulation, and hormone production.
Z. M. Gvozdikova, V. M. Anan'ev, I. N. Zenina, V. I. Zak · 1964
This 1964 Soviet study examined how superhigh-frequency (SHF) microwave radiation affects brain activity in rabbits and cats using EEG measurements. Researchers found that microwave exposure caused measurable changes in brain electrical activity that depended on field strength, exposure time, and which part of the body was irradiated. The study established that the central nervous system shows high sensitivity to microwave radiation even at non-thermal power levels.
Klimkova-Deutschova E · 1964
This 1964 Czechoslovakian technical report examined how radiation exposure affects human brain wave patterns measured by EEG (electroencephalogram). The research represents early documentation of electromagnetic field effects on the nervous system from behind the Iron Curtain. While specific findings aren't available, this work contributed to the growing body of evidence that radiation can alter brain function.
C. I. Barron, A. A. Love, A. A. Baraff · 1956
This 1956 study examined 226 radar workers exposed to microwaves for up to 13 years, comparing them to 88 unexposed controls. Researchers found blood cell changes in 25% of radar personnel (decreased immune cells, increased other cell types) and subjective symptoms like fatigue and headaches, though no major pathology was detected.
L. Sinisi · 1954
This 1954 conference paper by Sinisi examined brain electrical activity (EEG) in humans after radar exposure. The research represents one of the earliest documented investigations into how microwave radiation from radar systems affects human brain function. This pioneering study laid groundwork for understanding neurological impacts of electromagnetic field exposure.

This research by F. Brown examined how terrestrial electromagnetic fields influence animal orientation and navigation behaviors beyond visual cues. The study investigated connections between natural geomagnetic fields, circadian rhythms, and biological orientation mechanisms. This work helps establish the scientific foundation for understanding how animals naturally detect and respond to electromagnetic fields in their environment.

Researchers exposed rabbits, guinea pigs, and rats to 2450 MHz microwave radiation (the same frequency used in microwave ovens) until their body temperature reached dangerous levels. They found that different parts of the brain heated up differently than the rest of the body, with the brain's surface getting significantly hotter than internal brain areas and rectal temperature. This demonstrates that microwave radiation creates uneven heating patterns in the brain that vary between species.

Researchers examined how radio frequency electromagnetic fields affect brain wave patterns in rabbits using electroencephalogram (EEG) recordings. The study focused on changes in spindle waves and other brain activity patterns when rabbits were exposed to RF radiation. This type of research helps scientists understand how wireless signals might influence normal brain function.

Researchers exposed rats to 2.45 GHz microwave radiation at 40 mW/cm² for 2 hours, with some rats also receiving thyroid hormone injections to increase their metabolic rate. The study found that microwave exposure significantly increased stress hormone (corticosterone) levels and disrupted thyroid function, with effects amplified when combined with elevated metabolism.
