Possible effects of different doses of 2.1 GHz electromagnetic radiation on learning, and hippocampal levels of cholinergic biomarkers in Wistar rats
Authors not listed · 2021
Rats exposed to 65 V/m of 2.1 GHz radiation for one week showed impaired performance on memory tasks and reduced hippocampal cholinergic biomarker levels.
Plain English Summary
Researchers exposed rats to 2.1 GHz radiation at 45 V/m or 65 V/m for one week and compared them to a sham-exposed group. They tested memory using object location and Y-maze tasks. Rats exposed to 65 V/m performed worse on both memory tasks. The same rats had lower hippocampal levels of the cholinergic biomarkers AChE, ChAT, and VAChT.
Why This Matters
The researchers also performed numerical dosimetry simulations and found that the 65 V/m exposure produced high simulated SAR values. They suggested that the stronger effect at 65 V/m might be because the rats' snouts were closest to the antenna. The authors noted this was the first report of dose-dependent effects of short-term 2.1 GHz exposure on behavior and cholinergic biomarkers, and called for further mechanistic studies.
Exposure Information
Specific exposure levels were not quantified in this study.
