Plain English Summary
Researchers exposed rats to 2.45 GHz electromagnetic fields (the same frequency used in WiFi and microwave ovens) for 45 minutes and measured their anxiety levels using a standard behavioral test called the elevated plus-maze. The EMF exposure, at levels producing a specific absorption rate of 0.6-0.9 W/kg, did not change anxiety responses compared to unexposed control rats. This finding suggests that short-term exposure to this type of radiofrequency radiation does not affect anxiety-related behaviors in rats.
Study Details
In a first phase of this investigation, a validation of our elevated plus-maze apparatus was performed in male Sprague-Dawley rats
Testing anxiety response at various ambient light intensities (200, 30, 10 and 2.5 lux), as well as ...
As we made no a priori hypothesis on whether the effects would be anxiogenic or anxiolytic, part of ...
The present experiment demonstrates that exposure to EMFs, which was previously found to increase the number of benzodiazepine receptors in the rat cortex [Lai H, Carino MA, Horita A, Guy AW. Single vs. repeated microwave exposure: effects on benzodiazepine receptors in the brain of the rat. Bioelectromagnetics 1992;13(1):57-66], does not alter anxiety responses assessed in the elevated plus maze.
