916 MHz electromagnetic field exposure affects rat behavior and hippocampal neuronal discharge

摘要

Wistar rats were exposed to a 916 MHz,10 W/m2 mobile phone electromagnetic field for 6 hours a day,5 days a week.Average completion times in an eight-arm radial maze were longer in the exposed rats than control rats after 4-5 weeks of exposure.Error rates in the exposed rats were greater than the control rats at 6 weeks.Hippocampal neurons from the exposed rats showed irregular firing patterns during the experiment,and they exhibited decreased spiking activity 6-9 weeks compared with that after 2-5 weeks of exposure.These results indicate that 916 MHz electromagnetic fields influence learning and memory in rats during exposure,but long-term effects are not obvious.
