To investigate whether exposure to a pulsed high-frequency electromagnetic field (pulsed EMF) emitted by a mobile phone has short-term effects on the inhibitory control of saccades.
A double-blind, counterbalanced crossover study design was employed. We assessed the performance of 10 normal subjects on antisaccade (AS) and cued saccade (CUED) tasks as well as two types of overlap saccade (OL1, OL2) task before and after 30 min of exposure to EMF emitted by a mobile phone or sham exposure.
After EMF or sham exposure, we observed a slight but significant shortening of latency in the CUED and OL2 tasks. AS amplitude decreased as well as the saccade velocities in the AS, CUED, and OL1 tasks after exposure. These changes occurred regardless of whether exposure was real or sham. The frequencies of pro-saccades in the AS task, saccades to cue in the CUED task, and prematurely initiated saccades in the overlap (OL2) task did not change significantly after real or sham EMF exposure.
Thirty minutes of mobile phone exposure has no significant short-term effect on the inhibitory control of saccades.
The cortical processing responsible for saccade inhibition is not affected by exposure to EMF emitted by a mobile phone.
研究手机发射的脉冲电磁场（pulsed EMF）暴露是否对视动抑制产生短期影响。
采用双盲、交叉对照设计。我们评估了 10 名正常受试者在进行反扫视（AS）和提示扫视（CUED）任务以及两种重叠扫视（OL1、OL2）任务前后，在接受手机 EMF 暴露或假暴露 30 分钟后的表现。
在 EMF 或假暴露后，我们观察到 CUED 和 OL2 任务的潜伏期略有但显著缩短。AS 振幅减小，AS、CUED 和 OL1 任务中的扫视速度也降低。这些变化与暴露是真实的还是假的无关。在真实或假 EMF 暴露后，AS 任务中的前瞻性扫视频率、CUED 任务中的扫视到提示的频率以及重叠（OL2）任务中过早开始的扫视频率没有显著变化。
手机暴露 30 分钟对视动抑制的短期控制没有显著影响。
负责扫视抑制的皮质处理不受手机发射的电磁场暴露的影响。
