Effects of exposure to extremely low-frequency magnetic field of 2mT intensity on Spatial memory and learning in rat
Annals of General Psychiatry volume 9, Article number: S144 (2010)
Background
Extremely low-frequency magnetic fields (ELFMF), have been reported to produce a variety of biological effects, interfere with the activity of the brain and may cause behavioral and cognitive disturbances. Some efforts have been made to investigate the incidence of ELFMF on human health and animal physiology and behavior.
Materials and methods
30 male rats were completely divided into 3 groups (2 experimental and control). Exp1, group that were exposed EMFs (50 Hz ferqency, 2 mT intensity) for 20 minutes. Exp2, group that were exposed EMFs (60 Hz frequency, 2 mT intensity) for 20 minutes. For similar conditions control group were situated into set of EMFs for 20 minutes. Sapatial memory was done with Morris water maze (6 days, 4 trails).
Results
The results show that exposed to EMFs(50 Hz&60 Hz frequency, 2 mT intensity) are significantly better in practice related to spatial memory in comparison with control group.
Conclusions
Our results demonstrate that exposed ELFMF are significantly better in practice related to spatial memory in comparison with control group.
