Wistar rats were exposed to a 916 MHz, 10 W/m(2) 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.
将Wistar大鼠每天暴露于916兆赫、10瓦/平方米的移动电话电磁场中,每天6小时,每周5天。在暴露4至5周后,暴露组大鼠在八臂放射状迷宫中的平均完成时间比对照组大鼠更长。在6周时,暴露组大鼠的错误率高于对照组大鼠。在实验过程中,暴露组大鼠的海马神经元表现出不规则的放电模式,并且与暴露2至5周后相比,在暴露6至9周时它们的尖峰活动减少。这些结果表明,916兆赫的电磁场在暴露期间会影响大鼠的学习和记忆,但长期影响并不明显。
