View Original AbstractEMF exposure at everyday wireless device levels measurably altered cat brain wave patterns, suggesting our wireless environment may be continuously affecting neural function.
Plain English Summary
Russian scientists exposed cats to 980 MHz electromagnetic fields and monitored their brain waves. The EMF exposure shifted brain activity patterns from high frequencies to lower ones, mimicking effects of sound stimulation. This suggests electromagnetic fields may affect the brain through the same pathways as acoustic signals.
Why This Matters
This study provides compelling evidence that radiofrequency EMF exposure directly alters brain wave patterns at relatively low power densities. The 30-50 microW/cm² exposure level used here is well within the range of everyday wireless device emissions, making these findings particularly relevant for understanding how our constant EMF environment may be affecting neural function. What makes this research especially significant is the discovery that EMF appears to trigger brain responses through acoustic sensory pathways, potentially explaining why some people report hearing sounds or experiencing auditory sensations when exposed to certain EMF sources. The science demonstrates that even at these modest exposure levels, electromagnetic fields can measurably change how the brain operates, shifting fundamental electrical activity patterns that govern everything from attention to sleep.
Exposure Details
- Power Density
- 3- 5 µW/m²
- Source/Device
- 980 MHz
Exposure Context
This study used 3- 5 µW/m² for radio frequency:
- 300Mx above the Building Biology guideline of 0.1 μW/m²
- 5Mx 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.
Where This Falls on the Concern Scale
Study Details
The effect of modulated electromagnetic fields on the spectral parameters of bioelectric brain activity in awake cats was studied by registering the electroencephalogram from the skin surface in the vertex area using carbon electrodes
In the normal electroencephalogram, spectral components in the range above 20 Hz predominated. It wa...
The results suggest that there is a a common neurophysiological mechanism by which modulated electro...
