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 wate...
