To investigate the effects of extremely low frequency magnetic fields on the motor coordination of prenatally and neonatally exposed mice.
Mice were divided into three groups (n=7-18 per group): 1.) exposure of dams and offspring for 7 days after birth, 2.) exposure of dams during the last 7 days of pregnancy and 3.) control group. Motor coordination experiments were performed with the offspring in the age of 12 to 13 weeks.

The motor coordination of mice that were neonatally exposed to an extremely low frequency magnetic field was significantly impaired compared to the control group. However, no significant difference was observed between the prenatally exposed group and the control group.
