EFFECTS OF 60 Hz ENVIRONMENTAL ELECTRIC FIELDS ON THE CENTRAL NERVOUS SYSTEM OF LABORATORY RATS
Authors not listed
Laboratory study investigated whether 60 Hz electric fields from power lines affect rat brain and nervous system function.
Plain English Summary
This technical report examined how 60 Hz electric fields from power lines affect the central nervous system of laboratory rats. The study investigated whether the electrical fields surrounding power transmission equipment could influence brain and nervous system function in animal models. The research contributes to understanding potential neurological effects from power frequency electromagnetic field exposure.
Why This Matters
This research addresses a critical gap in our understanding of power line EMF effects on brain function. While most studies focus on magnetic fields from power lines, this investigation specifically examined electric fields - the component that's often overlooked but equally present around electrical infrastructure. The 60 Hz frequency is precisely what flows through every power line, substation, and electrical system across North America. What makes this particularly relevant is that electric fields from power lines can be quite strong near transmission corridors, sometimes reaching levels of several kilovolts per meter. Unlike magnetic fields that easily penetrate buildings, electric fields are more easily shielded by structures, but they remain a significant exposure source for people living near power infrastructure. The focus on central nervous system effects is especially important given growing concerns about neurological impacts from EMF exposure, including effects on sleep, cognitive function, and neurological development.
Exposure Information
Specific exposure levels were not quantified in this study. Duration: 30 days
Study Details
To examine the effects of simulated high voltage AC power line fields on daily patterns of movement, renal functions, growth, organ weights and blood pictures on rats.
Groups of 19 male albino rats were exposed to vertical 60 Hz electric fields of 0 (ambient), 50, 500...

These effects were taken as indication 1) a possible 'on' effect associated with the 1000 V/m field, and 2) an enhanced sensitivity to external stimuli associated with the 1000 V/m condition. It was suggested that clearer effects of this class might emerge in larger experiments involving these and greater field gradients.
