Effects of exposure to extremely low-frequency electromagnetic fields on spatial and passive avoidance learning and memory, anxiety-like behavior and oxidative stress in male rats

" During spatial reference memory test, animals in ELF-EMF exposure groups (100, and 2000 μT) spent more time in target zone (F (4, 55) = 5.699, P = 0.0007, One-way ANOVA). In PAL retention, the step through latency in the retention test (STLr) in ELF-EMF exposure groups (100,500, and 2000 μT) was significantly greater than control group (F (4, 55) = 29.13, P < 0.0001, One-way ANOVA). In EPM test, ELF-EMF exposure (500 and 2000 μT) decreased the percentage of the entries into the open arms (F (4, 55) = 26.31, P < 0.0001, one-way ANOVA). ELF-EMF exposure (100, and 500 μT) increased Malondialdehyde (MDA) concentration (F (4, 25) = 79.83, P < 0.0001, One-way ANOVA). Our results may allow the conclusion that exposure to ELF-EMFs can improve memory retention (but not acquisition) in the adult male rats. Although exposure to ELF-EMFs could be a factor in the development of anxious state or oxidative stress."
