Plain English Summary
Scientists exposed pregnant rats to 50 Hz electric fields from power lines and tested their offspring's brain responses as adults. The exposed rats showed delayed neural processing for vision and touch, plus increased brain damage markers, suggesting developmental electric field exposure causes lasting nervous system changes.
Why This Matters
This study reveals concerning evidence that extremely low frequency electric fields can disrupt normal brain development with effects lasting into adulthood. The 12 kV/m exposure level used here is higher than typical household environments but comparable to what you might encounter near high-voltage power lines or electrical substations. What makes this research particularly significant is that it demonstrates developmental vulnerability - the timing of exposure matters enormously, with effects persisting long after exposure ends. The researchers found clear evidence of oxidative stress, which provides a biological mechanism for how these fields might damage developing neural tissue. This adds to the growing body of evidence suggesting that our current safety standards, which focus only on heating effects, may be inadequate to protect developing organisms from non-thermal biological impacts of EMF exposure.

Study Details
The purpose of our study was to investigate the developmental effects of extremely low frequency electric fields (ELF-EFs) on visual evoked potentials (VEPs) and somatosensory-evoked potentials (SEPs) and to examine the relationship between lipid peroxidation and changes of these potentials.
In this context, thiobarbituric acid reactive substances (TBARS) levels were determined as an indica...
The latencies of VEP components in all experimental groups were significantly prolonged versus C gro...
In conclusion, alterations seen in evoked potentials, at least partly, could be explained by lipid peroxidation in the retina and brain.
