An attempt evaluation of the functional state of the cerebral synapses in rabbits exposed to the chronic action of microwaves
Edelwein Z · 1968
1968 rabbit study investigated chronic microwave effects on brain synapses, marking early scientific concern about EMF neurological impacts.
Plain English Summary
This 1968 study examined how chronic microwave exposure affects brain function in rabbits, specifically looking at the electrical activity of brain synapses (the connections between nerve cells) using electroencephalography. The research was among the early investigations into whether microwave radiation could alter normal brain communication patterns in living animals.
Why This Matters
This research represents pioneering work from an era when scientists first began questioning the biological effects of microwave radiation. What makes this study particularly relevant today is its focus on synaptic function - the fundamental communication system of the brain. The reality is that our current microwave exposure from WiFi, cell phones, and smart devices operates at similar frequencies but at power levels and durations that would have been unimaginable in 1968. While we can't know the specific findings without the full study, the very fact that researchers were investigating chronic microwave effects on brain synapses six decades ago suggests early recognition of potential neurological impacts. This type of foundational research laid the groundwork for understanding how electromagnetic fields might interfere with the delicate electrical processes that govern brain function.

Exposure Details
- Power Density
- 7 mW/cm²
- Exposure Duration
- 100-108 hours
Exposure Context
This study used 7 mW/cm² for radio frequency:
- 700Mx above the Building Biology guideline of 0.1 μW/m²
- 11.7Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.

Microwave radiation with impulse modulation and wavelength 10 cm at power density 7 mW/cm² affects the functional state of cerebral synapses. The action of d-tubocurarine is antagonistic to the effects of microwave radiation, suggesting that the microwave radiation's effect depends on the activation of synaptic activity. The results indicate that microwave radiation can influence the central nervous system through its effects on synaptic transmission.
