研究の主なアウトカム(著者による)

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.
