Russell L. Carpenter, Clair A. Van Ummersen · 1967
This 1967 study exposed rabbit eyes to microwave radiation at frequencies from 2.45 GHz to 10 GHz and found it caused cataracts in the lens. The location of the cataracts depended on how the radiation was delivered, and researchers noted the damage wasn't simply from heating but from some other property of the microwaves.
Ivanov-Muromskiy, K. A., Likhachev, A. I. · 1967
Soviet researchers in 1967 exposed human and rabbit heads to powerful 7000 gauss magnetic fields to study nervous system effects. They found the magnetic field decreased red blood cell sedimentation rates and hemoglobin while increasing white blood cell counts. In humans, brain exposure raised pain tolerance and reduced sensitivity to electrical stimulation.
D. P. Photiades, S. C. Ayivorh · 1967
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.
I. A. Kolomoitseva, G. D. Kusnetsova, M. S. Myslobodsky · 1967
Soviet researchers in 1967 studied how rabbit brain cortex responded to electromagnetic fields and light stimulation, finding that rhythmic electromagnetic exposure affected brain wave patterns and neuron activity.

This early research demonstrated that electromagnetic fields can directly influence brain electrical activity in living animals.
Ban K · 1967
Japanese researchers exposed 50 mice to microwave radiation at various power densities (6.8 to 43.4 mW/cm²) for 5 minutes daily over 7 weeks. Despite observing behavioral changes like face washing and avoidance behaviors at higher power levels, microscopic examination of organs showed no tissue damage. Only one mouse died during the study period.
S. F. Cleary, B. S. Pasternack · 1966
This 1966 study by Cleary examined eye lens changes in workers exposed to microwave radiation.

This was among the first studies to document potential eye damage from occupational microwave exposure.
Susan Korbel · 1966
This 1966 technical report examined how ultra high frequency radio waves affected rat behavior, representing early research into microwave radiation's biological effects. The study investigated behavioral changes in laboratory rats exposed to UHF radiation. This research contributed to the foundational understanding of how radio frequency energy might influence living organisms beyond just heating effects.
Bryan, Robert N. · 1966
Researchers in 1966 exposed rats to microwave radiation immediately after training them in a shock-avoidance task. Rats that received microwave exposure retained their learned response 24 hours later, but rats that were handled before the experiment lost this memory despite being capable of learning. This suggests microwave radiation may interfere with normal memory consolidation processes.
A. S. PETROV · 1966
This 1966 Soviet review examined how superhigh frequency (SHF) electromagnetic radiation affects the human body. The research found that microwave frequencies above 3000 MHz penetrate only about 1 cm into skin, while lower frequencies (1000-3000 MHz) can reach several centimeters deep, potentially affecting vital organs like the heart and brain.
Cleary SF, Pasternack BS · 1966
This 1966 study by Dr. S.F. Cleary examined biological effects of microwave radiation on humans, marking an early recognition that non-ionizing EMF could produce detectable biological changes. The research emerged as high-powered radar technology made it possible to generate microwave fields intense enough to study biological impacts. This was groundbreaking work establishing that lower-energy radiation like microwaves could affect living systems.
J. Richard Toleikis et al. · 1966
This 1966 study developed techniques to record individual brain cell activity in squirrel monkeys during electroanesthesia using 70 Hz electrical pulses. Researchers found they could measure how electrical current dramatically changed the firing patterns of single neurons in the brain's sensory-motor cortex. The work established methods for studying how electrical fields affect brain cell function at the most fundamental level.
J. A. Tanner · 1966
This 1966 study by J.A. Tanner examined how microwave radiation affects birds, investigating both thermal (heating) effects and behavioral changes.

This early work helped establish foundational knowledge about microwave radiation effects on living organisms.
Yu. A. Trifonov, I. A. Utina · 1966
This 1966 study examined L-type retinal cells in tortoises, finding that these cells produce electrical responses without changing their membrane resistance. Unlike typical nerve cells, these horizontal retinal cells showed electrical activity that didn't correlate with membrane potential changes, suggesting a unique mechanism of cellular response.
L. N. TUMARKINA, N. A. DUBROVSKII · 1966
This 1966 Soviet study examined how humans perceive amplitude-modulated signals (sounds that vary in loudness over time) using white noise and pure tones. Researchers investigated what auditory cues people use to detect these modulated signals and how training improves perception. The study explored fundamental mechanisms of how our hearing system processes information-carrying sounds.

Susan K. Eakin, William D. Thompson · 1965
Researchers exposed 20 male rats to UHF radio waves (300-920 MHz) for 47 consecutive days and tracked behavioral changes. The radiated rats initially became more active but grew less active over time, showed increased emotional responses, and took longer to recover from induced seizures. The study suggested these behavioral effects were non-thermal and related to changes in the nervous system.
