Neural Regen Res:电磁场暴露对海马神经元放电和大鼠行为的影响

来源:EurekAlert! 2012-07-31 20:13

中国神经再生研究(英文版)》杂志于2012年7月19期出版的一项关于“916 MHz electromagnetic field exposure affects rat behavior and hippocampal neuronal discharge”的研究报告。

文章中,研究者经过916MHz、10W/m2电磁场环境暴露的大鼠完成八臂迷宫实验的平均时间和平均错误率升高,且大脑海马区神经元一直呈现不规则放电模式,在暴露第6-9周时海马神经元每秒放电次数明显减少。

文章作者认为,这项研究体现了916MHz电磁场作用在一定阶段上影响了大鼠的学习和记忆能力,但实验未观察到远期的明显效果。(生物谷Bioon.com)

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

Dongmei Hao1 , Lei Yang1 , Su Chen2 , Yonghao Tian2 , Shuicai Wu1

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.
