View Original AbstractExposure to 3 Hz and 60 Hz ELF/EMF reduced locomotor activity and locus coeruleus firing rate in male rats, but did not affect anxiety-like behavior or short-term memory.
Plain English Summary
Researchers exposed male rats to 3 Hz and 60 Hz ELF/EMF using a protocol of two cycles of 2 hours per day for four days with a two-day interval. Immediately after exposure, locomotor activity was significantly lower in both exposed groups compared with sham-exposed rats. The exposure did not change anxiety-like behavior or short-term memory over the following two weeks. Electrophysiological recording showed a significant reduction in locus coeruleus firing rate after two hours of exposure. Proteomic analysis indicated global changes in the whole brain proteome after treatment.
Why This Matters
The study aimed to determine whether extremely low frequency electromagnetic fields at 3 Hz and 60 Hz could influence memory, anxiety, electrophysiology, and brain proteome in rats. Short-term memory and anxiety-like behavior were tested immediately and at one and two weeks after exposure.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 3 Hz and 60 Hz Duration: 2 cycles of 2 h/day exposure for 4 days separated with a 2-day interval
Study Details
In the present study, we investigated whether the exposures of ELF/EMF with frequencies of 3 Hz and 60 Hz can affect the memory, anxiety like behaviors, electrophysiological properties and brain’s proteome in rats.

Here, some evidence regarding the fact that such exposures can alter locomotor activity and neurons firing rate in male rats were presented.
