Electromagnetic waves are widely used in several applications. However, many unanswered questions remain about the effects of electromagnetic waves on living organisms. One of the investigations of such biological effects is the evaluation of behavior when a living body is exposed to electromagnetic waves. In a previous study, it was suggested that magnetic fields with a frequency of 400 kHz, exposure time of 24 hours, and magnetic field strength of 10 A/m may affect the behavior of mice. In the present study, we investigated the physiological significance of the influence on mice behavior under the same conditions. Mice with a locomotion meter implanted in their back were placed in a cage that generated magnetic field. We then compared the results with spontaneous brain substance in the absence of magnetic field exposure.
