A recent study reported the results of an exploratory study of alterations of the quantitative sleep profile due to the effects of a digital mobile radio telephone. Rapid eye movement (REM) was suppressed, and the spectral power density in the 8-13 Hz frequency range during REM sleep was altered. The aim of the present study was to illuminate the influence of digital mobile radio telephone on the awake electroencephalogram (EEG) of healthy subjects. For this purpose, we investigated 34 male subjects in a single-blind cross-over design experiment by measuring spontaneous EEGs under closed-eyes condition from scalp positions C3 and C4 and comparing the effects of an active (0.05 mW/cm2) and an inactive digital mobile radio telephone (GSM) system. During exposure of nearly 3.5 min to the 900 MHz electromagnetic field pulsed at a frequency of 217 Hz and with a pulse width of 580 microseconds, we could not detect any difference in the awake EEGs in terms of spectral power density measures.
最近一项研究报告了一项探索性研究的结果,该研究探讨了数字移动无线电话的影响导致的定量睡眠状况改变。快速眼动(REM)睡眠受到抑制,且REM睡眠期间8 - 13赫兹频率范围内的频谱功率密度发生了改变。本研究的目的是阐明数字移动无线电话对健康受试者清醒时脑电图(EEG)的影响。为此,我们采用单盲交叉设计实验,对34名男性受试者进行了研究,通过在闭眼条件下从头皮C3和C4位置测量自发脑电图,并比较有源(0.05毫瓦/平方厘米)和无源数字移动无线电话(GSM)系统的影响。在暴露于频率为217赫兹、脉冲宽度为580微秒的900兆赫脉冲电磁场近3.5分钟的过程中,我们在清醒脑电图的频谱功率密度测量方面未检测到任何差异。
