| 摘 要： | 本文对脑电主要机能试验之一——闪光诱发的理论依据及试验方法——作了进一步的探索,从而证实和丰富了控制论创始人之一Wiener的有关设想。作者应用数字谱分折技术研究正常人闪光诱发脑电信号,得出了清晰、明确的“节律同化”谱图及有关特征参数的数值范围,为进而研究各类病理状态打下了基础;为临床脑电图计算机化、为提高脑电图诊断的阳性率提供了依据.

| Abstract: | One of the main function tests in EEG (electroencephalography) is the flash stimulation. Its theory and experimental method are further explored in this paper. The postulation of Wiener-one of the originators of Cybernetics-is proved and enriched by our study. Authors of this paper studied EEG signals of normal persons under the condition of flash stimulation by using the digital spectral analysis technology. The clear and definite "rhythm synchronization" spectrum and digital range of the characteristic parameters are obtained. They provide the possible basis for studying the different pathological status of the patients. Our effort is paid for computerizing the clinical EEG data and increasing the positive diagnostic rate of EEG of the patients. |
