The reliability of steady-state visual evoked responses (VER's) was determined for nine normal subjects using Fourier analyses with 1.0 and 0.25 Hz bin resolutions. No correlations were found between VER amplitudes and subjects' reports of attention, accommodation, fixation, or perceived organization of the stimulus. Across subjects, there was also no sustained amplitude modulation of the VER by any frequency (including alpha), and frequency drift of the VER did not contribute significantly to its amplitude variability. Modeling, using mixed sine waves to simulate different signal/noise (S/N) ratios, established that a significant portion of VER amplitude variability can be accounted for by noise which occurs at the same frequency as the VER and which is not removed by ensemble averaging.
使用具有1.0赫兹和0.25赫兹频段分辨率的傅里叶分析，确定了9名正常受试者的稳态视觉诱发电位（VER）的可靠性。未发现VER振幅与受试者关于注意力、调节、注视或对刺激的感知组织的报告之间存在相关性。在所有受试者中，也没有任何频率（包括阿尔法波）对VER进行持续的振幅调制，并且VER的频率漂移对其振幅变异性的贡献不显著。通过使用混合正弦波模拟不同的信号/噪声（S/N）比进行建模，确定VER振幅变异性的很大一部分可归因于与VER频率相同且未通过总体平均消除的噪声。
