Comparing the Effects of Long-term Exposure to Extremely Low-frequency Electromagnetic Fields With Different Values on Learning, Memory, Anxiety, and β-amyloid Deposition in Adult Rats.
This animal study exposed adult male rats to 50 Hz ELF-EMF at 1, 100, 500, or 2000 μT for 1 hour/day over two months and assessed behavior and brain markers. The authors report increased memory retention (higher step-through latency) alongside increased anxiety-like behavior (reduced open-arm entries), particularly at higher intensities. No β-amyloid deposition was detected, while microglia counts increased in the 100–2000 μT groups.
Key points
- Fifty male adult rats were randomized into four exposure groups (1, 100, 500, 2000 μT) and a control group with no stimulation.
- Exposure was at 50 Hz for 1 hour per day for two months (8 weeks).
- Passive avoidance retention latency increased in the 100, 500, and 2000 μT groups compared with controls.
- Open-arm entries in the elevated plus maze decreased in exposed groups, especially at 2000 μT, consistent with an anxiogenic effect.
- No β-amyloid deposition was detected in the hippocampus in any group.
- Microglia numbers increased in the 100, 500, and 2000 μT groups compared with control and 1 μT.
- The authors conclude ELF-EMF induced oxidative stress, though specific marker results are not detailed in the abstract.
