Share:

Allan Frey's 1965 research established that electromagnetic fields can measurably affect brain function and behavior at non-thermal levels.

Plain English Summary

Summary written for general audiences

This 1965 review by researcher Allan Frey explored how electromagnetic energy affects behavior and brain function, examining multiple frequencies including UHF and infrared radiation. The study investigated the biological mechanisms behind electromagnetic field interactions with neural activity and brain tissue. This work helped establish the scientific foundation for understanding how EMF exposure can influence human behavior and brain function.

Why This Matters

Allan Frey's 1965 review represents pioneering work in understanding how electromagnetic fields interact with the human brain and nervous system. At a time when most scientists dismissed the possibility of non-thermal biological effects from EMF, Frey was documenting measurable changes in neural activity and behavior from electromagnetic exposure. This research laid crucial groundwork for what we now understand about EMF's ability to influence brain function at levels well below those that cause tissue heating.

The reality is that Frey's early observations about electromagnetic energy affecting behavior have been validated by decades of subsequent research. Today's ubiquitous wireless devices operate at many of the same frequencies Frey studied, yet regulatory agencies continue to rely on heating-based safety standards that ignore the behavioral and neurological effects his work helped identify. The science demonstrates that our brains are far more sensitive to electromagnetic fields than current safety guidelines acknowledge.

Study Details

To review research findings pertinent to psychologists and suggest lines of investigation regarding the influence of electromagnetic energy on behavior and the nervous system.

Though the areas of fingertip detection of color, neural emission of infrared energy, electron paramagnetic resonance techniques, and brain impedance shifts are in the embryonic stage of development, most are potentially of great significance in the understanding of the nervous system and behavior.

Quick Questions About This Study

Frey examined multiple electromagnetic frequencies including UHF (ultra-high frequency) and infrared radiation. His research investigated how different parts of the electromagnetic spectrum could influence neural activity and brain function, establishing early evidence for frequency-specific biological effects.
The study used brain impedance measurements and electron paramagnetic resonance techniques to detect changes in neural activity during electromagnetic exposure. These methods allowed researchers to observe biological responses in brain tissue that occurred without heating effects.
This research was groundbreaking because it challenged the prevailing belief that electromagnetic fields only affected biology through heating. By documenting behavioral and neural changes at non-thermal levels, it opened new understanding of how EMF could influence human health and brain function.
Frey concentrated on the nervous system, particularly neural activity and brain tissue responses to electromagnetic energy. His work examined how electromagnetic fields could alter brain impedance and influence behavioral patterns through direct effects on neural function.
Many of today's wireless devices operate at frequencies similar to those Frey studied, yet current safety standards ignore the behavioral and neurological effects his research identified. This early work provides scientific foundation for concerns about modern EMF exposure affecting brain function.
