ABSTRACT
The present study investigated the effect of extremely low frequency (8 mT, 50 Hz) electromagnetic fields (ELF-EMF) on avoidance learning in mice and compared the effect of an ELF-EMF in adult male and female mice. Learning was evaluated using a passive avoidance learning procedure in a standard wooden box, in which, despite their instinctive tendencies, mice learn to stay on a small platform to avoidant an electric shock. Before each learning session, the animals were exposed to an 8 mT, 50 Hz ELF created by a round coil. Immediately after 60 min exposure to the ELF-EMF, the mice were subjected to avoidance learning. The animals in the sham-exposed control group were placed in the coil for 60 min but were not exposed to the EMF and were subjected to the same behavioral procedures as the experimental group. The comparison of learned behaviors in the experimental and control groups showed that exposure to an 8 mT, 50 Hz ELF for 60 min significantly affected passive avoidance learning in both male (p < .023) and female (p < .015) mice.
