Electrical reaction of the rabbits cerebral cortex to various electromagnetic fields
Chizhenkova RA · 1967
1967 Soviet research showed electromagnetic fields cause measurable electrical changes in rabbit brain tissue, establishing early evidence of EMF neurological effects.
Plain English Summary
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.
Why This Matters
This research from 1967 represents pioneering work in understanding how electromagnetic fields interact with brain tissue at the cellular level. What makes this study particularly significant is that it used direct electrical measurements of brain activity, providing objective data about EMF's neurological effects rather than relying on behavioral observations alone. The fact that researchers were documenting measurable electrical changes in rabbit brain cortex over 50 years ago underscores how long scientists have recognized that EMF exposure can alter normal brain function.
The reality is that your brain operates through electrical signals, and external electromagnetic fields can interfere with these natural processes. While we don't have the specific field strengths or frequencies tested in this study, the research demonstrates that various types of electromagnetic exposure can produce detectable changes in brain electrical activity. This foundational work helped establish the biological plausibility for EMF effects on human neurological function that we continue to study today.

Exposure Context
This study used 40 mwatt/cm² for radio frequency:
- 4,000Mx above the Building Biology guideline of 0.1 μW/m²
- 66.7Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
This study used 460 oersteds for magnetic fields:
- 2.3Kx above the Building Biology guideline of 0.2 mG
- 460x above the BioInitiative Report recommendation of 1 mG
This study used 30 v/m for electric fields:
- 100x above the Building Biology guideline of 0.3 V/m
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.

Electrical reactions in the brain appear only under the action of electromagnetic fields on the animal's head. The EEG changes are not accompanied by a change in the respiratory and cardiac rates.
