However, the effect of EMF on human being is controversial. Several epidemiologic and experimental studies have shown that EMF has a harmful effect on central nervous system of animals. Previous research works in our laboratory, using light microscopes have shown that EMF could produce morphological changes in Cerebellum. The aim of the present study is to investigate ultrastructural changes of Cerebellum in EMF-exposed rats. Materials and Methods: 30 wistar rats were exposed to 3 mT EMF for 4 hours/day in a period of 4 months. After the experimental period rats in control and experimental groups were killed and tissue samples from their Cerebella were prepared for electron microscopic studies. Statistical analysis was performed by means of SPSS software and t-test. p M3 ER -
