The 50 Hz (10 mT) sinusoidal magnetic field: effects on stress-related behavior of rats. med./bio.

Published in: Bratisl Lek Listy 2012; 113 (9): 521-524

Aim of study (acc. to author)

To examine potential behavioral changes in rats exposed to a 50 Hz-magnetic field (10 mT, sinusoidal).

Main outcome of study (acc. to author)

No differences between the exposed group and the control group were observed regarding locomotor activity and exploration behavior. However, in the exposed group, rats showed significantly more anxiety in the elevated plus maze when compared to the control group.
The authors conclude that exposure to 50 Hz-magnetic field (10 mT, sinusoidal) could promote anxiety-related behavior in rats.
