K. MAJEWSKA · 1968
Polish researchers examined 400 people - 200 microwave-exposed workers and 200 controls - to assess eye damage from occupational microwave exposure. The study found evidence of harmful eye effects from microwave radiation at levels considered safe by workplace regulations, but only after prolonged exposure of 4-5 years or more. This 1968 research provided early evidence that regulatory limits might be insufficient for long-term protection.
Edelwein Z · 1968

The research was among the early investigations into whether microwave radiation could alter normal brain communication patterns in living animals.
H. W. Ludwig · 1968
This 1968 research by Ludwig proposed a theoretical mechanism for how natural electromagnetic pulses from lightning (called atmospherics) might be absorbed by the human nervous system. The study focused on extremely low frequency (ELF) electromagnetic fields and their potential interaction with neural tissue, particularly at synapses where nerve cells communicate.

Stanisław Barański, Zbigniew Edelwejn · 1968
This 1968 study exposed 65 rabbits to microwave radiation while administering various neurological drugs, measuring brain wave activity through electroencephalograms. Researchers found that microwaves altered how the brain responded to these drugs, changing tolerance levels and brain electrical patterns. The findings suggest microwaves can directly affect the brain's reticular formation, which controls arousal and consciousness.
Allan Fraser, Allan H. Frey · 1968
Researchers in 1968 discovered that active crab nerve cells emit electromagnetic radiation in the micron wavelength range (0.3-10 micrometers), while inactive and dead nerves do not. The study showed this emission comes from specific biological processes in functioning nerves, not just general heat radiation from living tissue.
LOBANOVA EA · 1968
This 1968 Soviet study examined how periodic microwave exposure affects mice, focusing on standardizing exposure protocols for safety research. The researchers investigated reflex responses and radiation effects to help establish maximum permissible exposure levels. This represents early foundational work in microwave safety standards development.
Willard E. Caldwell, Frank Russo · 1968
This 1968 exploratory study examined how AC magnetic fields affect the behavior of Italian honey bees, motivated by concerns about how space travel might impact living organisms when removed from Earth's natural magnetic environment. The researchers developed experimental methods to test magnetic field effects on animal behavior, though specific findings aren't detailed in the available abstract.
S. V. Nikogosyan, I. A. Kitsovskaya · 1968
Soviet researchers exposed rats to decimeter wave radiation (110 mW/cm²) for 60 minutes daily and found it decreased cholinesterase activity in the brain. Rats that were already sensitive to noise showed the most dramatic changes, suggesting pre-existing nervous system conditions may amplify EMF effects.
STANISLAW BARANSKI, ZBIGNIEW EDELWEJN · 1967
Polish researchers exposed 70 male rabbits to microwave radiation for 60 days, measuring brain wave activity and examining brain tissue under microscopes. They found that chronic microwave exposure at power levels that didn't heat the tissue still caused measurable changes in brain function and structure. Pulsed microwaves produced more pronounced effects than continuous waves.
Constant PC, Jr · 1967
This 1967 study investigated whether humans can actually hear electromagnetic waves, particularly microwaves, as some people had reported. The research aimed to determine if this auditory sensation was real and whether people could learn to detect EM radiation through hearing.
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.
Eustace F. G. Douglas et al. · 1967
Researchers applied 70 Hz electrical currents to macaque monkeys' heads to study how electroanesthesia affects brain responses. They found that increasing electrical current intensity gradually suppressed brain activity in key thalamic regions until responses disappeared completely at anesthetic levels. The study demonstrates that external electrical fields can directly interfere with normal brain function.
Itsuo Yamaura, Shiko Chichibui · 1967
Researchers exposed crayfish and prawn nerve clusters to 11 gigahertz microwave radiation at 300mW/mm² power density. The microwaves suppressed normal nerve firing patterns, with stronger radiation causing longer suppression periods. This 1967 study provided early evidence that microwave radiation can directly disrupt nervous system function in living organisms.
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.
Arthur S. Wilson, Sanford J. Larson, Anthony Sances, Jr. · 1967
Researchers tested squirrel monkeys' decision-making abilities after electroanesthesia (electrical current used for surgical anesthesia) to measure true recovery time. While monkeys could move almost immediately after the electrical current stopped, their cognitive performance remained impaired for about 30 minutes, revealing that apparent physical recovery doesn't equal complete neurological recovery.
Edward J. Zuperku et al. · 1967
Researchers applied 70 Hz electrical currents to squirrel monkeys' heads and measured how this affected their visual system's electrical responses. They found that these currents disrupted normal brain processing of visual information, with different parts of the visual pathway responding differently to the electrical interference. This demonstrates how external electrical fields can interfere with the brain's normal electrical activity.
Milton M. Zaret · 1967
This 1967 study by Dr. Milton Zaret examined how microwave radiation affects rabbit eyes, specifically investigating lens damage and cataract formation.

J. A. Tanner, C. Romero-Sierra, S. J. Davie · 1967
This 1967 study examined how microwave radiation affects birds, finding that chickens exposed to 'slightly thermal' microwave fields (20-50 mW/cm²) showed immediate escape and avoidance behaviors within seconds. The research demonstrated that microwave radiation produces both thermal effects (heating) and non-thermal effects (cellular changes) that can trigger rapid behavioral responses in animals.
John M. Davies, David I. Randolph · 1967
This 1967 US Army symposium examined flash blindness, a temporary vision impairment caused by intense light exposure. Researchers studied visual performance recovery in both cats and humans using electroretinography and behavioral testing. The research focused on understanding how bright flashes affect vision and how quickly normal sight returns.
Russell L. Carpenter, Clair A. Van Ummersen · 1967
This 1967 study exposed rabbit eyes to microwave radiation at frequencies from 2.45 to 10 GHz and found it caused cataracts in the lens. The researchers discovered that the location and type of cataract depended on how the eye was exposed, and that repeated shorter exposures could accumulate to cause damage. Importantly, the evidence suggested these cataracts weren't simply caused by heating effects.
P. C. Constant, Jr. · 1967
This 1967 conference paper by PC Constant Jr. explored the phenomenon of electromagnetic wave hearing, focusing on how humans can perceive microwave radiation as auditory sensations.
