溴氰菊酯分装工人脑电功率谱电子计算机分析

Computer Analysis of EEG among Workers Exposed to Deltamethrin in the Workplace

本文采用电子计算机对溴氰菊酯分装工人的脑电信号进行了功率谱分析。结果表明,该法与脑电图的目测分析相比有较多优点,它能够获得较多的脑电有效信息,还可以进行较细致的定量分析,精确度高,分析客观,从而使脑电信号中的有效信息得到了进一步的开发和利用。脑电信号的功率谱分析结果显示了接触组与对照组在一些指标上有差异。作者认为脑电信号的电子计算机功率谱分析,在进一步观察化学物质对脑功能的影响方面具有重要的参考价值。

The paper is to report that the computer analysis of electroencephalogram of 4 workers exposed to deltamethrin and 3 workers of control group were observed. The results primely showed that the computer analysic of workers, EEG power spectrum has more advantage than routine analysis of electroencephalogram. Many indices of EEG power spectrum were different between the exposed group and control group. It suggests that the computer analysis of electroencephalogram has significant value of reference in observing toxic effect of chemical substance on the function of brain.
