Recently, electromagnetic fields around ultra-high voltage transmission lines have received considerable attentions for their potential biological effects. This study aimed to investigate the effects of static electric field (SEF) and power frequency electric field (PFEF) on cognition. Mice were exposed to SEF and PFEF with the same strength (35 kV/m) for 49 days, respectively. Behaviors in Morris water maze test and amino acid neurotransmitter levels in hippocampus were examined during exposure. Results indicated that the exposure of 35 kV/m SEF would not cause significant influences on learning and memory ability in mice, while the exposure of 35 kV/m PFEF would cause significant positive effects on learning and memory ability in mice on day 33. This difference in effects from SEF and PFEF on cognition was possibly induced by the difference in the degree of molecular polarization and ion migration in organisms under exposure of two kinds of electric fields with different frequency.
最近，超高压输电线路周围的电磁场因其潜在的生物学效应而受到相当多的关注。本研究旨在探讨工频电场（PFEF）和静电场（SEF）对认知的影响。将小鼠分别暴露于相同强度（35kV/m）的 SEF 和 PFEF 中 49 天。在暴露期间，通过 Morris 水迷宫测试和海马氨基酸神经递质水平来检测行为。结果表明，35kV/m SEF 的暴露不会对小鼠的学习和记忆能力产生显著影响，而 35kV/m PFEF 的暴露会在第 33 天对小鼠的学习和记忆能力产生显著的积极影响。SEF 和 PFEF 对认知的影响差异可能是由两种不同频率的电场作用下生物体内分子极化和离子迁移程度的差异引起的。
